| Abstract: | In order to study the best method for tissue culture and rapid propagation for Amelanchier alnifolia Nutt., stems with buds were chosen as explants. The results of in vitro culture showed that the shoot differentiation medium was MS+IAA 0.1 mg/L+6-BA 0.5 mg/L+KT 0.5 mg/L,the optimum medium for proliferation was MS+IAA 0.1 mg/L+6-BA 2.0 mg/L, GA_3 has no positive effect on the growth of shoot, the best medium for rooting was 1/4 MS without hormones, the rooting rate reached 87.9%. |
