Abstract

Gooseberry is one of the common berry crops in Siberia. But despite its merits, the gooseberry is characterized by a weak development of plant phytomass when propagated by stem cuttings, and as a result, a decrease in the quality of planting material. The results of studies of various backgrounds of non-root fertilizing showed that the variant using exogenous treatments of Zn 1% + Cu 1% + 6 micronutrient elements showed an increase in the area of the leaf blade to 12.9 cm². The accumulation level of copper, zinc, manganese and cobalt on plots using leaf fertilizing exceeded the control. Non-root feeding of Zn 1% + Cu 1% + 6 micronutrients of gooseberry when growing planting material by the green cuttings method increases the level of micronutrient accumulation (Zn, Co, Mn) in the leaves and activates growth processes – contribute to the development of assimilation surface.
