The Department of Dendrology traditionally conducts research on the biology, ecology, breeding, and cultivation of introduced and native woody plants, with an emphasis on their stability. Observations are carried out on a stationary basis in the systematic collections of the Arboretum of the M.M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (NBG) and in the plantings of Kyiv. The scientific direction “Geobotanical Park Science” involves the assessment of certain types of garden and park landscapes by comparison with native forests, based on which, or in place of which, the park was created. In the direction of developing the theory of the phytogenic field, new data were obtained on its communication aspect and impact on morphogenetic processes. A collection policy was developed to outline the directions of development of the Arboretum collections. Based on many years of phenological observations, it was found that changes in average annual temperature over the last climatic period shifted the dates of the onset of the initial phases of development in model plants. Studies of reproductive biology have revealed that the largest number of juniper seeds are aborted during the pollination-fertilization stages; that the quality of pine seeds depends on the number of trees in a single-species group; and that forsythia seeds in the NBG collection are produced in small numbers due to the predominance of clones with long staminal filaments. The result of the department’s breeding programs is the production of complex high-yielding hybrids of the genus Salix L. for the needs of renewable energy, landscaping and phyto-amelioration; dwarf seedlings of the fruit-bearing form of Chinese lilac (Syringa × chinensis f. fructiferum Gorb.), which have significant prospects for becoming a dwarf rootstock for varieties of common lilac; decorative cultivars of the genera Pinus L. and Picea A.Dietr. Biotesting of soils at a site with perennial cultivation of Syringa vulgaris L. plants showed higher soil toxicity in areas with intensive anthropogenic load. A comprehensive assessment of the resistance of plants of the genus Hamamelis Gronov. ex L. revealed that H. mollis Oliver is more resistant to insufficient moisture levels. For Rutaceae Juss. representatives, there is no clear fixation of a single reproductive system; a wide range of forms characterizes them, from hermaphroditic to dioecious, with numerous intermediate states. Comprehensive studies of this family have revealed species- and sex-specific differences in metabolite accumulation and drought resistance.
