Некоторые особенности строения побеговых систем и кроны молодых генеративных деревьев Tilia platyphyllos Scop. в умеренно континентальном климате в разных условиях биотопа

Abstract

The structure of the upper part of the crown of young trees of generative Tilia platyphyllos Scop. was investigated in temperate continental climate in the two biotopes with differnt lighting conditions. The architectural approach leads to revealing five types of biennial shoots systems in the apical branches: growth I and its transformations growth II, transitional, filling branching and filling nonbranching type. These types are quite different in terms of their morphological characteristics, duration of existence in the crown, their role in the axis system and the functions to perform. The article identifi es the changes in the growth systems of I type that adapts the brunch structure to the lighting conditions: an increase in the angle of the shoot branching and an increasing number of short-life lateral shoots. The features of the formation of more or less dense crowns in different lighting conditions were showed.

Структура верхней части кроны молодых генеративных деревьев Tilia platyphyllos Scop. исследована в умеренно-континентальном климате в двух биотопах, различающихся условиями освещенности. На основании архитектурного подхода в верхушечных ветвях выделено пять типов двулетних побеговых систем: ростовой I и его трансформации ростовой II, переходный, заполняющий ветвящийся, заполняющий неветвящийся. Выделенные типы различаются по морфологическим характеристикам, длительности существования в кроне, положением в системе осей и выполняемой функции. Выявлены изменения в ростовых системах I типа, адаптирующие структуру ветви к условиям затенения: увеличение угла ответвления боковых побегов и увеличение количества короткоживущих боковых побегов. Показаны особенности формирования более или менее плотной кроны в разных условиях освещенности.
