Efficiency of introduction in culture of in vitro of high-quality material of the pear in depending on extent of his defeat by the necrosis

Different pear varieties shoots were tested for the presence of endophytic microbiota and necrosis extent of the plants under study. Individual response of pear plant genotype and dependence for introduction of varietal material in vitro conditions on the degree of adaptation to biotic stress factors was. Tested shoots of different pear varieties for the presence of endophytic microbiota, as well as the extent of damage the necrosis of the plants under study. Identified the individual response of the genotype of plants pears, the dependence of the introduction of varietal material in in vitro conditions on the degree of adaptation to biotic stress factors. Conducted testing different varieties of pear in sprouts the existence endophytic microbiota and the incidence of necrosis of the studied plants. Individual response identified genotype of plants pear, the dependence of the introduction of long material in vitro conditions the degree of adaptation to biotic stress factors. Held testing of escapes of various grades of a pear for existence of an endofitny microbiota, and also the accounting of extent of defeat by a necrosis of the studied plants. Individual reaction of a genotype of plants of a pear, dependence of introduction of high-quality material to in vitro conditions on extent of adaptation to biotic a stress factors is revealed.
