INFLUENCE OF REMOTE CHERRY HYBRIDS ON ITS GROWTH AND DEVELOPMENT IN THE GARDEN

Abstract

In the experimental garden of All-Russian Research Institute of Fruit Crops Breeding (VNIISPK) for 2017-2020 were studied scion-rootstock cherry combinations of the institute selection. Years of tree planting are 2013-2014, scheme is 5x2 m, density - 1000 trees / ha. The objective of the research is to assess the influence of distant cherry hybrids on its growth and development in the garden. The influence of rootstock forms Novella and Turgenevka plants varieties is presented. The general condition of cherry plants was good and varied from 4.2 to 5.0 points, the degree of flowering was at the level of the control variant. During the years of study, the indicator of the fruiting degree in the Novella variety was higher. The Novella variety trees on forms 74324, 74363, Ts-8-101 are medium-grown. Restrained growth of Turgenevka variety plants was observed in combinations with rootstock forms 74324 and 74340; medium-grown plants – 74322, 74332, 74336, 74363, Ts-8-1014; tall – growing – 82987. Plants of the Turgenevka variety in combinations 74324 and 74336 showed incompatibility, breaking off at the place of grafting concretion. The greatest value of the length of the one-year shoot was noted in Novella variety on the rootstock 74340, and the smaller one was in Ts-8-101. In cultivar Turgenevka a longer one-year shoot length was noted on forms 74332 and 74363, the smallest - 74336. The best rootstock forms among those studied in terms of growth and development for cultivar Novella are 74322, 74332.74340, 82987, Turgenevka – 74322, 82987.
