Solation of plum scion-rootstock combinations for cultivation in arid conditions of the Northern Caspian sea

Abstract

Biological features of growth and fruiting of plum varieties of domestic and foreign selection were investigated, on the dwarf basement ВВА-1. It was established that at the age of 4 years the largest parameters of the crown were the trees of the varieties Burbank, Great Blue and Angelina (6.6–7.4 m3), smaller - varieties Bogatyrskaya, Volgograd and Kubanskaya early (3.5–4.2 m3), which allows to place these trees more. According to the speed, there were large-scale combinations of varieties Bogatyrskaya, Volgograd and Angelina, in which flowering was observed in the first year after landing in the garden. The highest productivity from the unit of section area and crown volume, in three years of fruiting, on the basement of the ВВА-1, was allocated varieties Bogatyrskaya, Volgograd and Kubanskaya early, which are suitable for cultivation according to intensive technologies. The maximum weight of the fruit is observed in Angeline variety -79.3 g.
