Micropropagation of some grape varieties in Kazakhstan

The article shows the improvement of the process of initiation into in vitro the culture and the clonal micropropagation of grape varieties. The optimal culture media for the initiation and cloning of grapes in vitro have been selected. During initiation on Murashige and Skoog, agar medium with ½ or ¾ concentration of macroand micronutrients and hormones (0.5 mg/l BAP and 0.1 mg/l IBA) is optimal. For micropropagation is suitable MS medium modified by some elements of mineral nutrition: 825 mg/l NH4NO3, 166 mg/l CaCl2, 15 mg/l ferrum chelate; best hormonal composition depends on variety: a) 0.5-1 mg/l BAP and 0.1-0.5 mg/l IBA; b) 0.5 mg/l 2-iP and 0.5 mg/l GA3
