Effect of KT on anthocyanin content in callus of brier grape (Vitis davidii Foёx)

Using the long-term maintained and purplish red callus of brier grape as test material, the effect of different KT concentration on its anthocyanin and proanthocyanidinscontent was investigated in this paper. The result showed that the anthocyanin and proanthocyanidins synthesis of brier grape callus could be regulated effectively by KT. The optimal medium was MS+2,4-D 1.0 mg/L+KT 0.05 mg/L, the anthocyanincontent and proanthocyanidinscontent were up to 66.95 μg/g(FW) and 3947.50 μg/g(FW), and they were 2.44 times and 1.68 times as control respectively.
