Cornus officinalis (Cornaceae) has Chinese origin, its reintroduction at the M.M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine started in 1993.
The objectives of this research were: to investigate the biometric parameters of fruits and leaves of C. officinalis genotypes, C. officinalis × C. mas hybrid ‘Etude’ and genotype from the grafting C. officinalis on C. mas under cultivation in the M.M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine, and to determine the degree of adaptation of C. officinalis to the climatic conditions of Ukraine (in particular, Right-Bank Forest Steppe) for selection of promising genotypes for further breeding work.
Material and methods. We used: a) 26-year-old maternal plant obtained from a two-year-old seedling in 1993 received from the nursery “Northwoods Wholesale Nursery” Mollala (Oregon, USA), where it was grown as an ornamental plant; b) seedlings of the maternal plant; c) cultivar Etude, which is an artificial hybrid from crossing C. officinalis × C. mas; and d) genotype obtained from grafting C. officinalis on C. mas. In our experiment, the maternal plant is indicated as G-01, while other plants – as G-02–G-08 genotypes. We determined the biometric parameters of the fruit (length, diameter, and weight), endocarp (length, diameter, and weight), pedicel (length and thickness), leaf blade (length, width, and the number of lateral veins) and petiole (length, width, and thickness). We examined the dynamics of fruit and endocarp formation during the season (genotypes G-01–G-03 and G-05) and compared the biometric characteristics of the fruit of genotypes G-01–G-05 from crops of two years, 2010 and 2018, which were most favorable in weather conditions. We have processed quantitative data in the PAST 2.10 software. The differences between the samples were estimated using the Tukey-Kramer test. The degree of variability was determined by the coefficient of variation. To assess the level of variability, we used the classification of Mamaev (1975).
Results. We have found that the largest fruits in 2010 were observed in the genotype G-01 and the smallest – in the genotype G-03. The coefficient of variation of the linear parameters of the fruit and endocarp was in the range 5.7–10.1 %; the level of variability was very low or low. The variability of fruit weight and endocarp was high; the coefficient of variation was from 7.0 up to 28.3 %. The amplitude of the linear parameters of the leaf was wide (coefficient of variation was from 9.8 to 31.0 %). The cultivar Etude differed from other C. officinalis genotypes in size and weight of (M = 1800 mg, max = 2400 mg) and a much wider amplitude of variation in the length (17.9–22.6 vs. 14.3–18.2 mm) of the fruit. The largest leaves were in the genotypes G-08 and G-01, and the smallest – in the genotype G-02. The cultivar Etude did not differ so much by the mean leaf morphometric indices and number of veins, but it demonstrated one of the broadest leaf blades (51.5 mm).
Conclusions. The data obtained in this study is important for the commercial use of C. officinalis and the cultivar Etude as food and medicinal plant, as well as for breeding in climatic conditions of Ukraine and analysis of hybridization features in the genus Cornus in general. |

Abstract
In the context of global climate change, the current strategy of agroeconomics focuses on the introduction
of unique plant species and the selection of new commercially important cultivars adapted to the dramatic
weather changes. Cornus officinalis (Cornaceae) has Chinese origin, its reintroduction at the M.M. Gryshko
National Botanical Garden, National Academy of Sciences of Ukraine started in 1993.
The objectives of this research were: to investigate the biometric parameters of fruits and leaves of
C. officinalis genotypes, C. officinalis × C. mas hybrid ‘Etude’ and genotype from the grafting C. officinalis
on C. mas under cultivation in the M.M. Gryshko National Botanical Garden, National Academy of
Sciences of Ukraine, and to determine the degree of adaptation of C. officinalis to the climatic conditions
of Ukraine (in particular, Right-Bank Forest Steppe) for selection of promising genotypes for further
breeding work.
Material and methods. We used: a) 26-year-old maternal plant obtained from a two-year-old seedling
in 1993 received from the nursery “Northwoods Wholesale Nursery” Mollala (Oregon, USA), where it
was grown as an ornamental plant; b) seedlings of the maternal plant; c) cultivar Etude, which is an
artificial hybrid from crossing C. officinalis × C. mas; and d) genotype obtained from grafting C. officinalis
on C. mas. In our experiment, the maternal plant is indicated as G-01, while other plants – as G-02–G-08
genotypes. We determined the biometric parameters of the fruit (length, diameter, and weight),
endocarp (length, diameter, and weight), pedicel (length and thickness), leaf blade (length, width, and
the number of lateral veins) and petiole (length, width, and thickness). We examined the dynamics of
fruit and endocarp formation during the season (genotypes G-01–G-03 and G-05) and compared the
biometric characteristics of the fruit of genotypes G-01–G-05 from crops of two years, 2010 and 2018,
which were most favorable in weather conditions. We have processed quantitative data in the PAST
2.10 software. The differences between the samples were estimated using the Tukey-Kramer test. The
degree of variability was determined by the coefficient of variation. To assess the level of variability, we
used the classification of Mamaev (1975).
Results. We have found that the largest fruits in 2010 were observed in the genotype G-01 and the
smallest – in the genotype G-03. The coefficient of variation of the linear parameters of the fruit and
endocarp was in the range 5.7–10.1 %; the level of variability was very low or low. The variability of fruit
weight and endocarp was high; the coefficient of variation was from 7.0 up to 28.3 %. The amplitude of the
linear parameters of the leaf was wide (coefficient of variation was from 9.8 to 31.0 %). The cultivar Etude
differed from other C. officinalis genotypes in size and weight of (M = 1800 mg, max = 2400 mg) and a much

Introduction
Modern climate change is related to rising
temperatures, increasing carbon dioxide
concentrations, the widespread melting
of snow and ice, and raising the world’s
ocean level (Schneider, 2004; Shindell,
2007; Ceccarelli et al., 2010). Droughts have
increased in Ukraine over the past 15 years,
both in intensity and frequency, that affected
yields. Further climate change may result in
increased temperature extremes, especially
in the southern part of Ukraine (Fileccia
et al., 2014). One of the ways of adaptation to
adverse climate changes is the minimization
of the risk of crop losses by the introduction
of new plant species and the selection of
new cultivars resistant to sudden weather
changes, heat shock and drought (Crossa et al.,
2017; Taunk et al., 2017; Ortiz, 2018). In this
aspect, Cornus L. species, the introduction,
and acclimatization of which have already
begun in the M.M. Gryshko National Botanical
Garden of the NAS of Ukraine (NBG) are very
promising (Klymenko et al., 2017a, b).
The genus Cornus includes nearly 60
species, distributed mainly in the northern
boreal and temperate regions, as well as in
the tropical and subtropical (rarely) mountains
of America, Eurasia, and Africa (Murrell &
Poindexter, 2016). This genus has always
attracted the attention of botanists and
breeders. The structure of inflorescences (Feng
et al., 2011; Zhang et al., 2013), morphology and
anatomy of fruits (Morozowska et al., 2013;
Woźnicka et al., 2015; Moradi et al., 2019) and
leaves (Klymenko & Klymenko, 2017), general
biological features (Weaver, 1976; Reed, 2004;
Prevéy, 2020) and reproductive biology
(Cornescu & Cosmulescu, 2017), systematics
(Wangerin, 1910; Hutchinson, 1942; Takhtajan,
1987), species composition in different regions
of Europe (Poyarkova, 1950, 1951; Klimenko,
2004), Asia (Xiang & Boufford, 2005) and North
America (Ferguson, 1966; Murrell & Poindexter,
2016), phylogenetic relationships (Murrell,
1993; Xiang et al., 2006; Yue et al., 2018), the
evolution of morphological characters (Eyde,
1988), peculiarities of evolution (Manchester,
2010; Atkinson, 2016; Stockey et al., 2016) and
biogeography (Xiang et al., 2006; Call et al.,
2015) were widely investigated. The family
Cornaceae Bercht. et J. Presl, including the
genus Cornus, is also the object of molecular
studies (Yu et al., 2017; Fu et al., 2017; Li et al.,
2020). Much attention has been recently paid
to the study of the chemical composition
and antioxidant activity (Kryvoruchko &
Kryvoruchko, 2018; Klymenko et al., 2019),
pharmacological (Hosseinpour-Jaghdani
et al., 2017; Huang et al., 2018) and medicinal
application (Dinda et al., 2016; Yue et al.,
2018; Czerwińska, & Melzig, 2018) of Cornus
species, as well as their commercial value
(Krośniak et al., 2010; Kazimierski et al., 2019).
Cornus species contribute to the diversity of
wild genotypes and serve as potential for the
breeding of the new varieties (Brindza et al.,
2007; Cornescu & Cosmulescu, 2017; Jaćimović
& Božović, 2017; Szot et al., 2019).
The genus Cornus is relatively uniform
in flower structure and leaf morphology,
but very heterogeneous in the structure of
inflorescences and morphology of bracts
and fruits (Murrell, 1993; Zhang et al., 2013;
Murrell & Poindexter, 2016). This fact results
in the delimitation of four to ten sections and
subgenera, which sometimes are considered
as separate genera (Wangerin, 1910; Poyarkova,
1951; Takhtajan, 1987).
Cornus s. str. comprises four species:
C. chinensis Wangerin (native to Central China),
C. sessilis Torr. ex Dur. (naturally growing in
the western part of North America (California
and Oregon), C. officinalis Siebold et Zucc.
(aboriginal to the north of Central and South-
Eastern China, where occurs in forested areas
at 400 to 1500 (2100) m altitude; also cultivated
in Japan and Korea) and C. mas L. (the natural
range includes Southern and partly Central
Europe to the Balkans, Asia Minor, and the
Caucasus). In Ukraine, C. mas grows naturally
Conclusions. The data obtained in this study is important for the commercial use of C. officinalis and the
cultivar Etude as food and medicinal plant, as well as for breeding in climatic conditions of Ukraine and
analysis of hybridization features in the genus Cornus in general.

in the Crimea, as well as on the narrow
Transnistria strip from the western border
of Ivano-Frankivsk to the northern part of
the Odesa region. In addition to the Crimean
range, C. mas is distributed in mountain
forests and hillsides in Transcarpathia. One
such locality is in the vicinity of Botar village
and covers the area of about 30 hectares.
It is one of the largest natural populations of
C. mas not only in Ukraine but also in Europe
(Fodor, 1974). In some areas of Cherkasy and
Kirovograd regions, there are isolated natural
locations, and relict ‘cornelian cherry hills’
have been preserved along the Dnipro River
(Kleopov, 1990).
Cornus chinensis and C. sessilis are difficult
for cultivation and are almost not applied
in selection work (Weaver, 1976). However,
C. chinensis is used in Chinese folk medicine in
the same way as C. officinalis (Xiang & Boufford,
2005). C. mas is one of the most studied species
of the genus and, at the same time, one of the
most valuable fruiting representatives of the
Cornaceae family (Klymenko et al., 2017a, b,
2019). Its cultivated habitat covers almost
all Europe, partly North America and other
regions. C. mas is widely cultivated in private
farms in Austria, Italy, France, Poland, Czech
Republic, Slovakia, and especially in Bulgaria.
It has been used for hundreds of years as a
medicinal plant in Bulgaria, and many varieties
have already been created there (Klimenko,
2004; Klymenko et al., 2017a, b).
In Ukraine, cornelian cherry trees are
common in the private and farm gardens of
Zakarpattia, Ternopil, Vinnytsia, Cherkasy,
Zaporizhia, Khmelnytskyi, Poltava, and Kyiv
Oblasts and Crimea. The northern border of
the successful fruiting cornelian cherry passes
through Chernihiv – Hlukhiv. In Ukraine, the
cultivars of C. mas are widely introduced in
horticulture (Klimenko, 2004). In particular,
the most significant gene pool of cultivars
and forms of this species (30 cultivars and
about 100 forms) was collected at the NBG.
Hence, the most cornelian cherry assortment
in Ukraine consists of cultivars that originated
from NBG breeding.
Asian-originated species C. officinalis is
not widespread outside the natural range. In
Korea, and especially in Japan (locally called
sandzaki), medicinal cornel is cultivated for
edible fruits and as a medicinal plant (Cao
et al., 2016; Li et al., 2012). Since the 1870s, it
has also been cultivated, mostly in botanical
gardens, in Europe (Czerwińska & Melzig, 2018)
and North America (Ferguson, 1966; Xiang &
Boufford, 2005). It is interesting that in the
UK, C. officinalis is more frequently cultivated
as a garden plant than C. mas (Klymenko et al.,
2017a).
In China, C. officinalis has been grown
and widely used in traditional medicine for
thousands of years (Czerwińska & Melzig,
2018). And now, it is cultivated there as a
nationally protected medicinal plant thanks
to its medical and commercial importance
(Li et al., 2012). In Japan, plantings of seedlings
of wild and cultivated genotypes are used
to harvest medicinal raw materials. The
cultivation of plants beyond their natural
growth is of great importance. It is based
on the individual variability of these plants.
Therefore, valuable forms were selected from
nature and transferred to the culture. The
diversity of the chosen forms is explained
by the fact that the plantations in amateur
gardening are mostly represented by seedling-
derived material, which is heterozygous.
Taking into account that cornelian cherries
are cross-pollinated plants, the seeds of the
original forms usually do not preserve in such
collections.
Pharmacological studies showed that
vegetative raw materials of C. officinalis
have neuroprotective, anti-diabetic, anti-
inflammatory, antioxidant, and cardiovascular
effects. The biochemical composition and
medicinal properties of C. officinalis fruits have
been extensively studied, especially in Japan,
Korea (Krośniak et al., 2010; Kryvoruchko
& Kryvoruchko 2018) and China (Cao et al.,
2016; Ji et al., 2019). There was almost no
breeding work for this species. Only in China
explorations on the phenotypic and genetic
diversity of local cultivars and wild genotypes
are conducting (Li et al., 2012). Before the
1990s, the collection, evaluation, conservation,
and use of C. officinalis germplasm had a
high scientific priority. The Laboratory of
Development of Endangered Chinese Raw
Narcotic Resources (North-Western China) has
now collected 73 samples of nine germplasm
types. Morphology and phytochemistry
confirmed the differences among these
germplasm types (Li et al., 2012), and, hence,
are promising tools for their investigation.
For Ukraine, C. officinalis is a new and
28 Plant Introduction • 85/86

promising food and medicinal plant. It is
cultivated only in the botanical gardens, in
particular in the O.V. Fomin Botanical Garden
of Taras Shevchenko National University of
Kyiv. The introduction of C. officinalis in the
NBG is closely related to the establishment of
the collection of Cornaceae at the Dendrology
Department, considering the possibility
of its comprehensive application (i.e., as
fruiting, medicinal, ornamental and timber
plants). C. officinalis was a part of the first
batch of Cornus species, the mass planting of
which began in early 1949. Unfortunately, in
subsequent years, this collection, including
C. officinalis, died due to an incorrectly
selected planting place and lack of irrigation (at
the early stages it is essential), which caused
insufficient winter hardiness and, finally,
death of plants. Later, in 1993, C. officinalis
was successfully reintroduced at the NBG.
Since then, comprehensive and intensive
introductory, biological and ecological
studies of this species are carrying out at the
Department of Acclimatization of Fruit Plants.
The morpho-biological features of
C. officinalis and C. mas are similar, with
differences in leaves and fruits. The fruits are
similar in shape and color. However, fruits of
C. officinalis are smaller but remain on the
plant for a long time after full ripening. The
leaves of C. officinalis are glossy, dark green,
rounded, or rounded ovate with elongated-
pointed and often twisted apex, wedge-shaped
base, and tufts of brown hairs in the corners of
the largest lateral veins. In C. mas, leaves are
bluish-green, oval, or elliptical with a gradually
pointed apex and a rounded or wedge-shaped
base and tufts of colorless hairs in the corners
of the largest lateral veins.
The NBG is currently breeding this species
to use the results of spontaneous intraspecific
variation in the selection of the most promising
forms. The work is focused on obtaining the
interspecific hybrids of C. officinalis × C. mas
that produce large long-maturing fruits.
In particular, at the NBG, C. officinalis plants
were artificially pollinated with C. mas pollen
(a mixture of pollen of ‘Lukyanovsky’ and
‘Olena’ cultivars) and thus obtained a cultivar
Etude.
For the mass vegetative propagation
of cultivars of cornelian cherry, different
species of the Cornaceae family were tested
as rootstocks. The best compatibility for
vegetative propagation has been found
in C. mas and C. officinalis. Ideal growth
of grafted components of both C. mas on
C. officinalis and C. officinalis on C. mas
(85–90 %) was observed, which is explained
by their close phylogenetic affinity. Other
Cornaceae species (C. kousa Bürger ex Miq,
C. florida L., C. nuttallii Audubon, Swida spp.)
were found incompatible with C. mas and
C. officinalis.
At the NBG, C. officinalis plants and
cultivar Etude bloom profusely and produce
fruits. They are undemanding to cultivation
conditions, grow successfully on various soils
(from acidic to alkaline), and are characterized
by high winter resistance. These plants are
also highly decorative (Klymenko et al., 2017a).
The introduction experiment on the
acclimatization of C. officinalis in Ukraine
continues. Present work aimed: a) to
investigate the biometric parameters of
fruits and leaves of C. officinalis genotypes,
C. officinalis × C. mas (cv. ‘Etude’) and genotype
from the grafting C. officinalis on C. mas under
cultivation in NBG; and b) to determine the
degree of adaptation of C. officinalis to the
local climatic conditions (in particular, Right-
Bank Forest Steppe of Ukraine) and selection
of promising genotypes for future breeding
work.
Material and methods
Biological material
For the study we used: a) 26-year-old
maternal plant obtained from a two-year-old
seedling received in 1993 from the nursery
“Northwoods Wholesale Nursery” Mollala
(Oregon, USA), where it was grown as an
ornamental plant; b) seedlings of the mother
plant; c) cultivar Etude, which is an artificial
hybrid from crossing C. officinalis × C. mas;
and d) genotype obtained from grafting
C. officinalis on C. mas. In our experiment, the
maternal plant is indicated as G-01, while other
plants as G-02–G-08 genotypes respectively
(Table 1).
Biometric analysis
The following quantitative traits were used to
test selected genotypes: length, diameter, and
weight of the fruit and endocarp; length and

width of pedicel; length, width, and a number
of lateral veins of the leaf blade; length, width,
and thickness of the petiole. We examined
the dynamics of fruit and endocarp formation
during the season (for genotypes G-01–G-03
and G-05) and compared the biometric
characteristics of the fruit of genotypes
G-01–G-05 from crops of two years, 2010
and 2018, which were the most favorable
in weather-climatic conditions for fruiting
plants. The morphometric parameters of the
leaf were examined in the same genotypes
with the exception of G-04.
Statistical analysis
We have processed quantitative data using
the free data processing software PAST 2.10
(Hammer et al. 2001). We used the main
descriptors to characterize all the samples:
the arithmetic mean and its error (M ± m),
the minimum and maximum values (min-
max), and the coefficient of variation (CV, %).
The differences between the samples were
estimated using the Tukey-Kramer test. The
degree of variability was determined by the
coefficient of variation. To assess the level
of variability, we used the classification of
Mamaev (1975).
Results and discussion
Fruit biometric parameters
Genotypes of C. officinalis (Table 2; Fig. 1).
In 2010, the average length of fruits varied
from 13.8 to 16.5 mm, and diameter from 7.7
to 10.5 mm. The average length of endocarp
was 12.2–13.5 mm, and average diameter –
4.6–5.4 mm. The average length of pedicels
was 7.7–10.2 mm, and average width – 0.2–
0.6 mm. During October 2010, in G-01–G-03
genotypes, the mean value of fruit size and
endocarp increased by increasing the number
of large fruits. At the end of the autumn season
of 2010 (03.11.2010), the largest fruits were
in the maternal plant (genotype G-01), and
significantly smallest – in the genotype G-03.
Under favorable weather conditions, fruits of
G-01, G-02, G-03, and G-04 genotypes were
even larger, and the amplitude of traits shifted
toward higher values (Table 2). The linear

dimensions of the fruit and endocarp were
stable. Their coefficient of variation (CV)
in most genotypes did not exceed 7 %,
which corresponds to a very low level of
variability. Rarely CV varied from 7.1 % to
10.1 %. The average values of fruit weight and
endocarp of the C. officinalis genotypes were
600–1000 and 200–300 mg, respectively.
The amplitude of variation in fruit weight in
2010 was 400–1800 mg, and in 2018 it shifted
toward larger values, but the magnitude
of variation was smaller, 1000–1700 mg.
Endocarp weight varied within 100–400 mg.
The lowest weight, 200 mg, was fixed for the
genotype G-02. In 2010 (03.11.10), CV for the
fruit weight was 11.8–20.1 % (mean variability),
and in 2018 (01.11.18), it decreased significantly
to 8.4–9.4 % (low variability). The smallest
variation was observed in fruit weight, while
endocarp weight was characterized by a
high level of variability with a CV reaching
7.0–27.9 %.
The cultivar Etude, within average values
of the size and weight of its fruits, was almost
indistinguishable from maternal plant and
seedlings of C. officinalis (Table 2). However,
the fruits of ‘Etude’ in 2018 were much larger
(length reached 19.9 mm, and diameter –
11.1 mm) than those of the maternal plant and
seedlings. The cultivar Etude significantly
differed by increased variation in fetal length
(17.9–22.6 vs. 14.3–18.2 mm), but was almost
stable by fruit diameter (Table 2). The mean
weight of the fruit was 1800 mg; the minimum
and maximum values shifted toward higher
values. The level of variability in fruit size
was very low (the highest CV = 5.75 %). The
maximum value of the coefficient of variation
of fruit mass in 2010 was 12.3 %, in 2018 –
12.8 %, hence, the level of variability was
intermediate. Statistical indicators, including
the coefficient of variation, size, and weight
of the endocarp, were similar to those of the
C. officinalis genotypes. The mean length of the

pedicels in the cultivar Etude varied from 12.4
to 14.0 mm, while in genotypes of C. officinalis
– from 9.0 to 11.6 mm. The pedicels of ‘Etude’
were slightly thicker.
Biometric parameters of leaves
Genotypes of C. officinalis (Table 3, Fig. 1). The
largest leaf blades had the genotypes G-08
and G-01, and the smallest – the genotype
G-02. Genotype G-02 had the smallest
span of variation in linear dimensions of
leaf length and width, 25.3 and 19.7 mm,
respectively. Corresponding leaf indices of
other C. officinalis genotypes varied within
38.6–49.9 and 26.1–43.1 mm, respectively.
The width of the leaf varied more than the
length (ranges were 7.2–13.5, and 9.8–18.9 mm,
respectively). The mean values of the number
of veins were 12.9–14.0 pieces per one leaf, and
the min-max values in the studied genotypes
were 10–18 pieces. The longest petioles had
the leaves of genotype G-08, and the shortest
– the leaves of genotype G-02. The level of
variation in length was low or intermediate.
The coefficient of variation was in the range
of 10.3–18.1%. Comparing to the length, the
width and thickness of the petiole were more
variable, and CV reached 26.7 and 31.0 %,
respectively.
Cultivar Etude (Table 3, Fig. 1). The
mean, minimum and maximum values and
CV of leaf blade size and petiole did not
differ significantly from respective values
of C. officinalis genotypes. However, the
variation of the width was much larger (with
registered 51.5 mm), whereas G-01 has only
35.4 mm, and G-07 – only 43.1 mm. The
number of veins on the leaf blade of ‘Etude’
also did not go beyond the amplitude of
variation designated for other genotypes.
Leaves of C. officinalis and cultivar Etude
were found relatively more variable in size,
with a low or intermediate level of variation.
The leaves of genotype G-08 had the highest
length and width and low CV. The genotype
G-05 was characterized by medium-sized
leaf blades and petioles with low or medium
variability, compared to other C. officinalis
genotypes.
As a result of the study, the biometric
parameters of the fruits, endocarp, and
pedicel were established in four genotypes
of C. officinalis and the cultivar Etude, and
leaf blade and petiole – in six genotypes of
C. officinalis and the cultivar Etude (Tables
2 & 3).
It is known that for the selection of
promising cultivars of fruiting plants, a
complex of indicators is applying. In particular,
fruit parameters play a crucial role in the
selection process. However, leaves, which in
the process of photosynthesis, ensure the
existence of the plant and accumulation of
nutrients in the fruits, are also important.
Quantitative traits are especially convenient
to control the condition of plants at all stages
of introduction and breeding – from initial
testing to variety testing, naturalization, and
‘complete’ acclimatization.
At the NBG, investigations of biometric
characteristics of fruits and leaves of non-
traditional species of fruiting, medicinal,
ornamental, and other commercially important
plants are conducting. These investigations are
mostly aimed at the evaluation of prospective
ways of cultivation of the new plant varieties in
conditions of temperate continental climate of
the Right-Bank Forest Steppe (Klymenko et al.,
2017a, b, c; Rakhmetov, 2018). In particular,
statistical indicators of variability have been
an integral part of bioecological research of
C. mas and its numerous cultivars and forms,
including those created at the NBG (Klimenko,
2004; Klymenko et al., 2019). Morphometric
characteristics of the fruit were examined in
different genotypes of Ziziphus jujuba Mill.
(Grygorieva et al., 2014), Elaeagnus multiflora
Thunb. (Grygorieva et al., 2018a), Mespilus
germanica L. (Grygorieva et al., 2018b),
Diospyros virginiana L. (Grygorieva et al., 2017),
Cydonia oblonga Mill. (Monka et al., 2014), as
well as in Persica Mill. taxa (Holubkova, 2017).
The obtained biometric data showed that the
fruits of the studied C. officinalis genotypes and
the cultivar Etude have no notable variability.
In most cases, the coefficient of variation
corresponded to a very low or low level of
variation (Mamaev, 1975). The most variable
sign was endocarp weight (Table 3). Hence,
we attribute endocarp weight to the category
of selectively important traits required for
the selection of new forms of C. officinalis.
Genotypes of C. officinalis and cultivar Etude
have responded favorably to weather and
climate conditions in 2018. According to

Airport (Zhuliany), Kyiv), 2018 was marked
by the optimum of precipitations in
May and August and significantly higher
monthly rainfalls in June. This indicates that
C. officinalis genotypes respond very well to
moisture. These indicators are important for
the development of agricultural measures for
the cultivation of C. officinalis in Ukraine.
There is still very little information on
the biometric indices of C. officinalis fruits
and leaves. This is probably because the
introduction and breeding of this species
are not widespread so much. The data about
the size and weight of the fruit of nine types
of germplasm, selected from 73 naturally-
occurring growth specimens in North-
Plant Introduction • 85/86 35
Biometrics of Cornus officinalis genotypes in the M.M. Gryshko National Botanical Garden
Western China (collection of the Laboratory
of Development of Endangered Chinese Raw
Narcotic Resources) were reported (Li et al.,
2012). The comparison shows that the limits of
variation of the mean fruit size in Chinese and
Kyiv genotypes are quite similar. The smallest
size of the fruit is practically the same, and
the maximum is larger in Chinese genotypes.
In particular, the maximum length of the
mature fruit in the G-04 was 16.7 mm, and in
the two Chinese genotypes – 19.1 mm. The
same tendency has been observed for fruit
weight. According to the Flora of China (Xiang
& Boufford, 2005), the fruits of C. officinalis
wild individuals may reach 12–18 mm long and
5–6 mm in diameter. The length of the fruits of
investigated genotypes is within the reported
range of variability for the wild species. Still,
in most cases, it is closer to the upper limit
of variation. However, the diameter of the
investigated fruits is almost twice higher in
comparison with wild species. Consequently,
the fruits of the introduced plants, both
Chinese and Kyiv, vary more in diameter than
in length. The fruits of the cultivar Etude,
which we examined, exceeded those of all nine
Chinese germplasm types by the size (e.g.,
length 19.9 mm vs. 19.1 mm, respectively) and
weight (1.8 mg vs. 1.6 mg, respectively). This
indicates the prospect of further breeding
work with ‘Etude’ in order to produce large-
fruited forms with long-fading after ripening
fruits.
The variability in leaf quantitative traits
is resulted from both their plasticity and
genotype variation, and thus reflects the
relationship between plant and climate
(Royer et al., 2008). Our current research
has confirmed this statement. We found that
the quantitative parameters of leaves of the
studied C. officinalis genotypes demonstrate
higher variation comparing to the fruits. The
biometric indices of the leaves, as well as the
fruits, in the studied genotypes were closer
(or beyond) to their variation in the wild
species reported by Xiang & Boufford (2005).
This fact, again, indicates that the genotypes
of C. officinalis introduced into the NBG
were sufficiently adapted to the temperate
continental climate of the Right-Bank Forest
Steppe of Ukraine. The leaves of cultivar Etude
were almost indistinguishable from the leaves
of C. officinalis genotypes. There was also no
significant change in the number of largest
lateral veins of the leaf because the wild
individuals of C. officinalis and C. mas are quite
similar in this respect. The leaves of C. mas
are characterized by 6–10 (12) lateral veins
(Poyarkova, 1951; Murrell & Poindexter, 2016),
and the leavevs of C. officinalis – by 12–14 veins
(Xiang & Boufford, 2005). Interesting was the
nature of inheritance of other morphological
features of the leaf blade by cultivar Etude.
The shape of the leaf, especially its apex
(gradually narrowed) and color (colorless, not
brown) of trichomes in the cultivar Etude, are
similar to C. mas. However, the number of
lateral veins in ‘Etude’ is closer to the maternal
species, C. officinalis. Thus, the cultivar Etude
is characterized by the combined inheritance
of leaf features.
Hybridization between Cornus taxa is still
a poorly investigated phenomenon. Having
nearly 60 species (Xiang & Boufford, 2005;
Murrell & Poindexter, 2016), this genus includes
only a few known species producing hybrids.
Both in natural conditions and botanical
gardens, C. florida, C. kousa, and C. nuttallii
from the subgenus Kraniopsis Raf. (Molnar,
2018) can hybridize with each other. Some
natural hybrids were also described between
C. racemosa Lam. and C. rugosa Lam. (Wagner,
1990). Prospective natural hybrids were also
reported between C. mas and C. officinalis
(Morozowska et al., 2013) and between
C. controversa Hemsl. and C. alternifolia L. f.
(Gawrońska et al., 2019). Thus, the data we
have obtained about the cultivar Etude
is important not only for clarifying the
characteristics of industrial use, but also to
investigate the peculiarities of hybridization
and to characterize the inheritance of traits in
the genus Cornus in general.
Conclusions
The value of biometric parameters of fruits and
leaves in the adaptation strategy of C. officinalis
plants and its hybrid under the conditions of
introduction were evaluated. Important and
indifferent signs for breeding work to obtain
promising productive varieties for industrial
cultivation were determined. Among the
cultivated at the NBG, the cultivar Etude and
genotypes G-03 and G-04 of C. officinalis
were the most noteworthy. Cultivar Etude is
promising for large-fruited forms with fruits

that do not fade long after ripening. The data
obtained indicate the strong potential of
C. officinalis for commercial use in Ukraine.
The results of this study are also important for
the investigation of hybridization in the genus
Cornus. Biometric characteristics of the fruit,
endocarp, and leaf were found determining
the degree of adaptation of C. officinalis to
the current climate conditions of Ukraine
(in particular, the Right-Bank Forest Steppe)
and essential for further breeding work.

за умов культивування в Національному ботанічному саду імені M.M. Гришка НАН України, для
з’ясування ступеня адаптованості виду до сучасного клімату України (зокрема, Правобережного
Лісостепу) і відбору перспективних генотипів для селекційної роботи.
Матеріали і методи. У дослідженні було використано 26-річну материнську рослину, отриману
дворічним саджанцем у 1993 році з розплідника “Northwoods Wholesale Nursery” (м. Молалла,
Орегон, США), де рослини цього виду вирощували як декоративні; сорт Етюд – гібрид від
схрещування C. officinalis × C. mas; генотип від щеплення C. officinalis на C. mas. У нашому дослідженні
материнську рослину позначено як G-01, а решту генотипів як G-02–G-08. Для цих рослин було
вивчено біометричні параметри плоду (довжина, діаметр і маса), ендокарпу (довжина, діаметр
і маса), квітконіжки (довжина і товщина), пластинки листка (довжина, ширина і кількість бічних
жилок) і черешка (довжина, ширина і товщина). Також було досліджено динаміку формування плоду
та ендокарпу протягом сезону (генотипи G-01–G-03 і G-05) та порівняно біометричні характеристики
плодів генотипів G-01–G-05 урожаю за два роки, 2010 та 2018. Ці роки було обрано, оскільки вони
вирізнялися дуже сприятливими для плодових рослин погодними умовами. Кількісні результати
було опрацьовано методами варіаційної статистики, з використанням безкоштовного програмного
забезпечення для наукового аналізу даних PAST 2.10. Мінливість показників було визначено за
допомогою коефіцієнта варіації. Різницю між зразками оцінено за допомогою тесту Тукі-Крамера, а
рівень мінливості – відповідно до класифікації Мамаєва (1975).
Результати. Було визначено біометричні параметри плода: довжина 13,8–19,9 мм, діаметр 7,7–
11,2 мм, маса 600–1800 мг; ендокарпу: довжина 12,1–13,8 мм, діаметр 4,5–5,4 мм, маса 200–300 мг;
квітконіжка: довжина 9,0–14,0 мм, товщина 0,2–0,6 мм; листової пластинки: довжина 73,5–117,1 мм,
ширина 73,5–75,2 мм, кількість бічних жилок 12,9–14,3; черешка: довжина 9,4–11,4 мм, ширина
1,3–2,1 мм, товщина 1,1–2,0 мм. У 2010 році найбільші плоди мав генотип G-01, а найменші – G-03.
Коефіцієнт варіювання лінійних параметрів плода та ендокарпу становив 5,7–10,1 %, що відповідає
дуже низькому або низькому рівню мінливості. Варіювання маси плодів та ендокарпа було більшим;
діапазон коефіцієнта варіювання від 7,0 до 28,3 %. Амплітуда лінійних параметрів листка широка.
Найбільші листки мали генотипи G-08 та G-01, найменші – генотип G-02. Сорт Етюд відрізнявся від
генотипів C. officinalis розміром та масою плодів врожаю 2018 року (М = 1800 мг, max = 2400 мг) та
значно ширшою амплітудою варіювання їхньої довжини (17,9–22,6 проти 14,3–18,2 мм). Сорт Етюд
за середніми морфометричними показниками листка та за кількістю жилок, у цілому, не відрізнявся
від досліджених генотипів C. officinalis, але ширина листкової пластинки була значно більшою і
становила 51,5 мм проти 35,4 мм (G-01) і 43,1 мм (G-07).
Висновки. Отримані дані важливі для комерційного використання C. officinalis та сорту Етюд як
харчових і лікарських рослин, а також для подальшої селекції сортів в погодно-кліматичних умовах
України і аналізу особливостей гібридизації у роді Cornus.

Гришка НАН України Klymenko, S.V. Ilyinska, A.P. In the context of global climate change, the current strategy of agroeconomics focuses on the introduction of unique plant species and the selection of new commercially important cultivars adapted to the dramatic weather changes. Cornus officinalis (Cornaceae) has Chinese origin, its reintroduction at the M.M.&nbsp;Gryshko National Botanical Garden, National Academy of Sciences of Ukraine started in 1993. The objectives of this research were: to investigate the biometric parameters of fruits and leaves of C.&nbsp;officinalis genotypes, C. officinalis × C. mas hybrid ‘Etude’ and genotype from the grafting C. officinalis on C.&nbsp;mas under cultivation in the M.M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine, and to determine the degree of adaptation of C. officinalis to the climatic conditions of Ukraine (in particular, Right-Bank Forest Steppe) for selection of promising genotypes for further breeding work. Material and methods. We used: a) 26-year-old maternal plant obtained from a two-year-old seedling in 1993 received from the nursery “Northwoods Wholesale Nursery” Mollala (Oregon, USA), where it was grown as an ornamental plant; b) seedlings of the maternal plant; c) cultivar Etude, which is an artificial hybrid from crossing C. officinalis × C. mas; and d) genotype obtained from grafting C.&nbsp;officinalis on C.&nbsp;mas. In our experiment, the maternal plant is indicated as G-01, while other plants – as G-02–G-08 genotypes. We determined the biometric parameters of the fruit (length, diameter, and weight), endocarp (length, diameter, and weight), pedicel (length and thickness), leaf blade (length, width, and the number of lateral veins) and petiole (length, width, and thickness). We examined the dynamics of fruit and endocarp formation during the season (genotypes G-01–G-03 and G-05) and compared the biometric characteristics of the fruit of genotypes G-01–G-05 from crops of two years, 2010 and 2018, which were most favorable in weather conditions. We have processed quantitative data in the PAST 2.10 software. The differences between the samples were estimated using the Tukey-Kramer test. The degree of variability was determined by the coefficient of variation. To assess the level of variability, we used the classification of Mamaev (1975). Results. We have found that the largest fruits in 2010 were observed in the genotype G-01 and the smallest – in the genotype G-03. The coefficient of variation of the linear parameters of the fruit and endocarp was in the range 5.7–10.1 %; the level of variability was very low or low. The variability of fruit weight and endocarp was high; the coefficient of variation was from 7.0 up to 28.3 %. The amplitude of the linear parameters of the leaf was wide (coefficient of variation was from 9.8 to 31.0 %). The cultivar Etude differed from other C. officinalis genotypes in size and weight of (M = 1800 mg, max = 2400&nbsp;mg) and a much wider amplitude of variation in the length (17.9–22.6 vs. 14.3–18.2&nbsp;mm) of the fruit. The largest leaves were in the genotypes G-08 and G-01, and the smallest – in the genotype G-02. The cultivar Etude did not differ so much by the mean leaf morphometric indices and number of veins, but it demonstrated one of the broadest leaf blades (51.5&nbsp;mm). Conclusions. The data obtained in this study is important for the commercial use of C. officinalis and the cultivar Etude as food and medicinal plant, as well as for breeding in climatic conditions of Ukraine and analysis of hybridization features in the genus Cornus in general.
