Abstract
The far-east forests are unique forest formation. One of the representatives of these forests is Manchurian apricot (Armeniaca mandschurica (Maxim.) B. Skvorts.). Because of its minor stocks it is listed in the Red Book and it is a subject to the protection and breeding. Last decades growth stimulants are used while growing planting material. The study of the possibility of their use while growing Manchurian apricot, which is one of the valuable tree species, has scientific and national economic significance. The goal of this research is the study of the influence of fertilization of apricot seedlings by growth stimulants of chemical and natural origin which were not used while growing of planting material of the family Rosaceae. The research was carried out on the nursery of Gornotaeshnoe station DVO RAN. Root and outside root fertilization of year- old apricot seedlings by solution of growth stimulants: appin, zircon, krezatcina and fumar were used. The efficiency of fertilization was identified. The work was carried out by conventional forestry techniques. Growth rates of year-old seedlings meet the requirements of the standards only at feeding by zircon. Root fertilization led to strong active growth of year- old seedlings using all the stimulants, but the most effective are appin and zircon. When growing planting material of Armeniaca mandschurica (Maxim) B. Skvorts., zircon and appin may be recommend as the most effective tree growth stimulating factors.
