摘要
以加拿大紫荆‘森林火焰’(Cercis canadensis‘Forest Pansy’)当年生嫩枝为试验材料,探讨不同培养基和植物生长调节剂如6-BA、IBA、NAA、TDZ对试管苗增殖以及生根的影响。结果表明:最适增殖培养基为DKW+TDZ0.03mg/L+PVP0.5mg/L;生根培养基为1/2MS+IBA25mg/L+AC0.6mg/L。此体系中增殖系数可达4.27,生根率73.3%。
Young stem sections with buds ofCercis canadensis‘Forest Pansy’were used as explants for experiment. The effects of culture mediums and PGRs such as 6-BA,NAA,IBA,TDZ on proliferation and rooting of test-tube plantlets were discussed. The results showed that the medium suitable for proliferation was DKW＋TDZ 0.03 mg/L＋PVP 0.5 mg/L,the optimum rooting medium was 1/2 MS＋IBA 25 mg/L＋AC 0.6 mg/L. In this system,the highest propagation coefficient was 4.27 and the rooting rate was 73.3%.
