Analysis of modern technologies for growing cherry varieties in temperate climates

Abstract

The research relevance is predefined by the need to optimise fruit crop cultivation systems considering weather conditions. The research aims to test the grafting technology of intensive sweet cherry plantations on small and medium-sized rootstocks. The leading method in achieving the research goal was a field experiment. The main results of this study are as follows: the leading technologies for increasing the yield of sweet cherry varieties depending on the impact of environmental stress factors are presented; the use of clone rootstock technology in sweet cherry plantations in temperate climates is substantiated. According to a set of indicators of productivity formation, the yield of plantations of different designs was predicted. Namely, the scheme of variety-rootstock combinations of intercalary placement, its length, and parameters of the growth complex for plants were revealed; indicators of physiological activity, growth, productivity, fruit quality, and economic efficiency in intensive sweet cherry plantations were determined. It has been established that the application of this technology will increase yields and improve the quality parameters of sweet cherry fruits by developing varieties with compact crowns, which will allow to compact the plantations. It has been analysed that climatic conditions are the main factor in the process of harvest formation. A list of stress factors of temperate climate that affect the yield of sweet cherries has been identified. It is proved that the introduction of clonal rootstock technology is the most effective for growing intensive plantations of sweet cherries in a temperate climate. Practically, the research aims to determine and test a set of elements of physiological indicators of the potential yield of sweet cherry plantations of different designs, to introduce them into production and use them in further breeding
