Вплив позакореневого підживлення комплексними мікродобривами на фотохімічну активність листків пшениці м’якої

Abstract

In greenhouse experiments was shown, that foliar treatment of plants of soft wheat varieties Zymoyarka of flag leaf stage (39) by complex of macro- and micronutrients contributes to enrich PS II photochemically active centers, reduce non-renewable Qb-complexes that do not participate in the linear electron transport and increase the intensity of assimilation carbon. The efficiency of PS II activation depends on the composition and balance macro and microelements in fertilizer, particularly nitrogen, phosphorus and potassium.
