Biological peculiarities of cherry growth and fructification on seedling and clonal rootstocks

Abstract

Cherry is a stone fruit crop which is valued for early raping, yield capacity, fruit eating qualities. The drawback is growth of trees, absence of short rootstocks for cultivating in Central chernozemic region. The Faculty of Agricultural Science conducts research on the selection of compatible cultivars and rootstocks with high winterhardiness of the above-ground part and roots for their introduction into commercial orchards in the Voronezh region. Biometrical attributes of cultivar growth and development, crown parameters, weak-, medium, active plantings of the cherry on seedling and clonal rootstocks have been determined by the study. The effects of cultivar-rootstock combinations on the cherry yield have been determined. The content of sugar, organic acids, dry basis, and vitamin C have been determined. The cultivars for introduction and study have been suggested for intensive commercial orchids of the Voronezh region.
