The optimal medium for the leaf of Zuoshan-1 was MS+BA 5. 0 mg/L+NAA 0. 1 mg/L,and the inducing rate of adventitious buds was 2. 5%. The most effective medium for inducing adventitious buds from the petioles of Pingli-7 was MS+BA 7. 0 mg/L+NAA 0. l mg/L,and the inducing rate was 1. 95%. The optimum mediu...
