Effect of ultrafine metal particles and their oxides on antioxidant enzyme activity, spike productivity and grain quality of spring soft wheat

Abstract

The results of field experiments in the scope of studying the effect of various options of ultrafine metal particles, their combinations, oxides on the content of antioxidant enzymes (catalase, malondialdehyde) as well as carotenoids in the tillering phases, stem elongation and spring wheat ear stage are presented. The influence of the above options on the formation of spike productivity (number of grains and grain weight per spike) and grain quality indicators (hardness, unit, gluten amount) are considered.
