Establishment of regeneration system in Cerasus xueluoensis

A plant regeneration system via adventitious shoot formation from leaf explants of Cerasus xueluoensis was established. Several factors such as explant sterilizing time,hormone concentration and concentration of sucrose and so on were explored to optimize the regeneration system in virto. The result showed that the fully unfold leaves were selected as the most appropriate explant in spring. And the best basic medium is MS. With 6- BA(1. 0 mg / L) + NAA(0. 5 mg / L)+ Vc(20 mg / L) was the optimum medium for callus proliferation. And 20 mg / L Vc was best to inhibit C. xueluoensis callus from browning. MS + 6- BA(2. 0 mg / L) + NAA(0. 1 mg / L) + TDZ(2. 0 mg / L) + Vc(20 mg / L) was the optimum medium for shoot differentiation. And 3 /4MS + NAA(0. 1 mg / L) + sucrose(15 g / L) was the optimum medium for root differentiation. The rooting percentage was 100% after 27 days.
