Research rate of in vitro proliferation Malling apple (Malus domestica) rootstocks cv. M26 and cv. MM106

Apple belong to Malus Miller genus. Today, more of 10000 varieties known in the world, some of varieties are economic , resistance to diseases and sexual proliferation of ability. The vegetative rootstock (M26 and MM106) are early harvesting, yield is high and effect on quality of fruits. The subject of project is research kinds vegetative rootstock of varieties and number of subculture on rate of in vitro proliferation. The basal medium culture MS (Murashige , Skoog, 1962) supplemented with BAP (2 mg/l) and IAA (0.5 mg/l) have prepared. In M26 rootstock, length of stem (1.11 cm) increased during the second and third subcuktures. In mm106 and M26, maximum number of leaves (18.7 and 9.2) produced in two subculture and such as, length of stem elongated during the first subculture. The length of shoot and number of leaves increased with repetitive subcultures but on effected on branching.Apple belong to Malus Miller genus.
