【摘要】 以茎段营养芽为材料,进行了角茎野牡丹的快速繁殖研究。结果表明:培养基MS+BA 0.3 mg.L-1+NAA 0.01 mg.L-1最适宜芽增殖,增殖系数达到3.1倍;在培养基1/2MS+NAA0.3 mg.L-1上无根苗培养7 d生根率85.0%,20 d生根率100%,每苗平均根数6.3条。试管苗移植成活率95.0%。更多还原

【Abstract】 The rapid propagation of Tibouchina granulosa by using stem segment as materials was studied.The results showed that the optimal medium for inducing adventitious buds was MS+ BA 0.3 mg·L-1+ NAA 0.01 mg·L-1 and the proliferation of multiples was 3.1.After cultured 7 days on the medium of 1/2 MS+NAA0.3 mg·L-1,the rooting rate of shoots was 85.0% while after 20 days the rate reached 100% and the average number of roots was 6.3 The survival rate of the transplanted test-tube plantlets was 95.0%.更多还原
