STUDY OF LEAVES FACE MORPHOMETRIC PARAMETERS OF YARMOLENKO BIRCH

Abstract

Forests significantly influence the formation of climate, certain geographical regions and regions, regulate the balance of solar energy on the surface of the earth and in the atmosphere, the circulation of atmospheric heat and moisture, the water regime of lakes and rivers. One of the important functions of forests is that they are a valuable raw material for many sectors of the national economy. However, the usefulness of forests is not limited to wood products. Forests protect the soil from erosion, have sanitary, hygienic and recreational value, and have the ability to improve the environment. Forests provide shelter for many wild animals and positively influence the growth of many plants.

At present, forestry is entrusted with the protection of forests from fires, protection from pests and diseases, reforestation, conservation of biodiversity, control over the use of forests, that is, a complex of all activities related to the existence of forests. Rational development of forests, their reproduction, protection from fires and pests are the main tasks that are constantly set before foresters.

This article presents the results of a study of the morphometric parameters of the leaf blade of the Yarmolenko birch growing on the territory of the «Narynkol Forestry» KGA. Trial plots were laid in the forests, and a mass recount of trees was carried out. Taxation indicators were determined during the recalculation. As material for the study, model trees were randomly selected for collecting leaves, the morphometric parameters of the leaf plate were determined, and the results are presented in the form of tables and diagrams.
