| description | Introduction
The components of the crown phytomass play a key role in the plants life as they synthesize organic substances and take part in the gas interchange processes CO2 deposition and production of O2. Scots pine (Pinus sylvestris L.) is the main coniferous forest-forming species within the Northern Steppe of Ukraine.
The aim of the study was to develop the regulatory reference which can be applied to estimate the phytomass of the crown components of Scots pine trees within the Northern Steppe of Ukraine.
Materials and Methods
To investigate the aboveground components of the crown phytomass we used the data obtained on 20 temporary sample plots within the territory of Dnipropetrovsk Region. We also assessed the crown phytomass fraction of a tree by means of the Lakyda method (2002). In addition, the working mass data of biometric indicators for the sample trees were formed. It included age, diameter at breast height, tree height, the mass of tree greenery, the mass of branches, needle mass and relative density of stands. To calculate the phytomass of the crown components, we applied regression equations.
Results
In this article, we provide the results of the basic statistics calculation for the crown phytomass components for sample pine trees. The correlation analysis showed that there was a direct relationship between all crown components and all biometric indexes. We found out that the strongest relationship was between the mass of tree greenery, branches, and needles with a diameter at breast height.
Furthermore, we provide the equation of dependence of the crown phytomass fractions on the tree diameter and height, as well as on the crown diameter and length, the tree age and relative stand density. We discovered that a connection of crown components with different influencing factors can be described by the allometric regression equations with R2 from 0.41 to 0.80. Higher determination coefficients are noted for the equations used to calculate the phytomass of tree greenery and needles, whereas for branches phytomass they are less significant. All calculated mathematical models had a negative coefficient for the tree height which confirms the decrease in the concentration of phytomass of assimilating organs with the aging of stands. Accordingly, there was a negative correlation between the crown components phytomass accumulation and the height of the stand.
We calculated and provided in the article the fragment of standards to estimate the phytomass crown components for Scots pine trees. Thus, the phytomass of tree greenery, branches and needles grew with an increase of diameter at breast height. At the same time, we found out that the higher the trees of the same diameter, the less their analyzed parameters are. We also revealed the results of calculating the crown phytomass of pine trees in an absolutely dry state. A comparative analysis of the obtained results on the phytomass of pine tree greenery and branches with the data obtained for this species in Polissya, Forest-Steppe of Ukraine, Russia, and Kazakhstan was carried out.
Conclusions
The developed regulatory reference describes the components of crowns phytomass of Scots pine trees in detail. We concluded that it can be used to estimate the products of the species’ crown components within the Northern Steppe of Ukraine.

Представлено результати моделювання фітомаси компонентів крони дерев сосни звичайної, що формує штучні лісові насадження на території Північного Степу України. Наведено результати кореляційного аналізу та основні статистичні характеристики розподілу компонентів фітомаси крони модельних дерев. Виявлено тісний прямий кореляційний зв’язок між масами деревної зелені, гілок і хвої та значенням діаметра стовбура дерев. Розроблено математичні моделі, що описують фітомасу досліджуваних компонентів залежно від таксаційних ознак дерев сосни звичайної. Отримані регресійні моделі залежності компонентів крони від біометричних параметрів демонструють вищі коефіцієнти детермінації для рівнянь розрахунку фітомаси деревної зелені та хвої, тоді як для фітомаси гілок вони є менш значущими. Наведено результати розроблення нормативно-довідкового забезпечення для оцінювання компонентів фітомаси крони дерев сосни звичайної в абсолютно сухому стані. Значення фітомаси деревної зелені, гілок і хвої збільшується зі збільшенням значення діаметра, тоді як зі збільшенням висоти стовбура для всіх досліджуваних компонентів крони виявлено їхнє зменшення.
