Enzymatic activity of spring wheat plants in the treatment of seeds with biostimulants and UFP of metals

Abstract

The results of field experiments on the influence of different options of ultrafine metal particles, their oxides, their combinations, and biostimulants on the antioxidant activity of SOD, the content of malonovodialdehyde, and the amount of photosynthetic pigments in arid conditions are presented. The positive effect of the studied options of ultrafine metal particles and their oxides on the content of both types of chlorophyll is noted. There are phase of exit into the tube and the reduction of the type of chlorophyll b in the variants of the UFP of iron and silicon oxide and their combination. In the earing phase, an increase in the proportion of chlorophyll a over chlorophyll b was observed in most variants of the experiment. The amount of SOD enzyme under the action of metals UFP and their oxides increased, a positive effect among the biostimulant options was obtained by Agroverm and Siliplant. Biofertilizer Blago3 contributed to the reduction of the amount of malonovodialdehyde.
