Динамика фотосинтетической активности листьев молодых неплодоносящих деревьев груши в зависимости от применяемого иммунокорректора

Abstract

This paper shows the results of experiments concerning the effect of foliar fertilization on the photosynthetic activity of pear tree leaves. It was tracked the dynamics of the photosynthetic activity of pear tree leaves, depending on variety, plant age and applied foliar fertilizer. As a result, there were identified the most effective options for the non-fruit-bearing pear trees.
