Effect of complex chelate fertilizer on root tissue functional activity and performance grain of wheat soft winter
Abstract
The article is devoted investigations the effects of foliar treatment complex fertilizers with chelates оn functional activity in tissues of roots in connection with redox potential of cells and kinetics of release of protons from the root cells, as well as enzymatic activity: catalase, peroxidase, ATPase in tissues of roots and grain productivity of plant winter wheat varieties Smuglanka. Study shows that non-leaf feeding complex fertilizers chelates Fiziozhivlin+P, Breksil Mix, Master 18.18.18 and Plantafol 5.15.45 regulates the metabolism of a plant, including affecting the functional capacity of the tissues of roots, as reflected in the increasing activity of redox potential of cells and inhibition of the kinetics of release of protons from the root cells. Increasing the ATPase activity of the root tissues indicates a growing share and maintaining active biosynthetic and regulatory of processes under the influence of chelated fertilizers, in particular, of biosynthesis of organic molecules, that associated with increased the biomass of wheat plants according from the data obtained. Determination of the activity of the antioxidant ferments: catalase and peroxidase showed increased activity of catalase (І.ІІ.І.6) under foliar fertilizer processing Fiziozhivlin+P and of peroxidase (І.ІІ.І.7) on 32 % in contrast of the control roots plants. Our studies have shown increase in grain productivity with by foliar treatment of chelate complex fertilizers: Fiziozhivlin+P, Breksil Mix, Master and Plantafol that increased by 5,9; 6,4; 6,0 and 5,1 t/ha, respectively. Thus, treatment of complex chelate fertilizer improves the functional activity of the tissues of roots, promoting the growth of their potential absorption capacity, supporting high plant energy balance of the body, promotes the resistance of wheat to the effects of pathogenic factors and eventually leads to an increase of grain productivity.
