BIOCHEMICAL CHANGES IN APRICOT TREES WITH VERTICAL ZONALITY
Our objective was to study the changes in carbohydrate, nitrogenous substances and enzyme contents in various organs of apricot trees grown at different altitudes above sea level.
We have established that biosynthesis and oxidation processes in leaves, shoots and roots of apricot are intensified in the foothill zone at an altitude of 1250 m, compared to the plain zone (870 m).
10 to 12% of sugars and 20 to 21% of dry substances are accumulated in apricot fruits.
Vitamins C, B1 and B2 contents are increased on the average by 10 to 13%.
Activation of biosynthesis and metabolite consumption processes demonstrates the biochemical adaptation mechanism of plants to high insolation and short vegetation period of the foothill zone, providing the energy and productivity of trees.
