Berry bushes in the landscape architecture of urban megacities

Abstract

Along with traditional and popular berry crops in private gardens, there are few common types and decorative forms. The purpose of the research was to expand the range of ornamental shrubs in the landscaping of large Metropolitan areas and to popularize knowledge about new or little-known types of berry bushes. As a result of studies on the value of the adaptation coefficient, the studied shrub species were divided into three groups according to the degree of prospects. The most promising group consisting of 65% of samples was the first, whose representatives were characterized by high winter hardiness and the ability to complete seed propagation, decorative. The average prospective second group includes 20 % of the studied samples. This includes plants that remain decorative during the growing season, are able to reproduce by seeds, but they are less promising than the representatives of the 1st group, due to the inability to maintain decorativeness in the growing season and do not give offspring by self–seeding. The third group, which was not promising, included 15 % of samples. Species of shrubs belonging to this group are quite hardy, have the ability to seed propagation.
