The growing peculiarities of pear tree planting material in conditions of Her-Her community of Vayots Dzor region

Abstract

The current work pursues production goals, particularly from the prospect of expansion of pear tree nurseries. In our republic the great part of pear tree nurseries dries out due to the bacterial leaf blight, improper selection of rootstock and scion (grafter) varieties, as well as to the random selection of rootstocks. Analyses on the planting stock quality have been conducted during the work implementation in the nursery farm of Herher community considering the inosculation results of various rootstocks. Application of different rootstocks in the nursery farms promotes the establishment of saplings with high survival rate and productivity. It is impossible to develop the branch of horticulture in the Republic of Armenia without the operation of nuresery farm system and sustainable production of healthy, purebred, reliable and high quality planting material. It is relevant to use the seed plants of Willow-leaf pear tree and quince tree rootstock for the pear tree varieties investigated by our research group. Propagation via shrubs has been singled out as an efficient method for clonal rootstock propagation.
