Abstract
Abstract In short-term vegetative experiment studied the effect of the different combinations of nitrogen and zinc fertilizers on the chlorophyll content in the leaves of spring wheat plants of the Zlata variety. It is established that application of nitrogen fertilizers together with zinc in most combinations contributed to stabilization of synthesis processes of chlorophyll grains in the leaves of wheat. It is shown that in conditions of optimal water supply and in the conditions of ecological stress caused by drought the most optimal combinations were ammonium sulfate with zinc and urea with zinc. With optimal water supply in variants where were applied ammonium sulfate with zinc and urea with zinc was obtained an increase of the amount of chlorophyll (a + b) compared with control variant without zinc, as a result of the growth of the content of both chlorophylls a and chlorophyll b . In the conditions of named ecological stress, the amount of chlorophyll (a+b) was increased in the variant with the addition of ammonium sulfate mainly due to chlorophyll a. In the variant where was applied urea with zinc the amount of chlorophylls (a+b) increased as a result of growth of chlorophyll a and chlorophyll b. It is shown that in conditions of drought in the specified variants had been increasing the ratio og chlorophyll a and chlorophyll b due to growth of chlorophyll b which indicates about improvement of water balance inside of the plant cells and increasing a photosynthetic activity due to normalization of processes of photolysis of water.
