Walnut (Juglans Regia) Damage Indicators Under The Cold Air Flow In The Western Tyan-Shan Mountain System

Abstract

Walnuts are important among deciduous forests in mountainous areas. Soil protection and water management properties of these forests contribute to the various economy sectors development. In earlier times, walnut forests occupied a large area. But anthropogenic impacts: deforestation and livestock grazing are leading to a decline in the natural forests regeneration. As a sharp drop result in weather, trees are more susceptible to frost damage. In mixed forests, frost damage was less common on the side and lower branches of the walnut tree, mainly on the upper branches.
