Changes in the assimilation apparatus and the conducting of root of woody plants in various environmental conditions

Abstract

The features of the development of tissues of the assimilation apparatus and the conducting roots of Scots pine (Pinus sylvestris L.), larch (Larix sukaczewii Dyl.), birch (Betula pendula Roth) and poplar (Populus balsamifera L.), growing in extreme forest conditions, are investigated. Adaptive species-specific changes in the anatomical and morphological organization of woody plants were revealed. The average values of growth of wood, bark, integumentary tissues and mesophyll were established. It is established that wood increments change depending on extreme forest growing conditions.
