The application of foliar nutrition for perennial fruit planting has a positive effect due to ability to absorb the water together with dissolved ions and molecules through cuticle of leaves. The article presents the results of two years investigations of foliar nutrition by complex fertilizers in combination with Novosil and Epin bioactive substances and its effect on leaves structure and chlorophyll content in apple-tree vegetative shoots of the Prikubanskoe (scheme of trees location — 4.0×1.2 and 4.0×0.6 m) and Zarnitsa (scheme of trees location — 5×2 m) grades. At the summer period, in the conditions of insufficient humidity and negative action of higher air temperature, the foliar nutrition promotes to a rise of apple-tree adaptive resistance: the increase of mesoxerophytic properties of foliar apparatus and the content of chlorophyll (a + b) in leaves. The combination of mineral fertilizers with Novosil preparation was efficient both on thinned out trees location and on compact planting. The application of fertilizers together with Epin preparation was more effective on the thick planting.
Keywords: apple-tree, fertilizers, foliar fertilizing, chlorophyll, leaf anatomy.
