The result showed that treatment of 500 mg·L -1 IBA or 500 mg·L -1ABT is better than other treatments. It also showed that the biennial cuttings treated with 500 mg·L -1IBA are more active than the annual cuttings with same treatment, and its rooting rate reaches to 100%. But the rooting rate of the annual cuttings is higher than that of the biennial cuttings treated with 500 mg·L -1 ABT, the rooting rate reaches to 90%.展开更多
从曼地亚红豆杉(Taxus x media)树皮内表皮中分离得到1株产紫杉醇的内生真菌O60B1,并通过高效液相色谱法(HPLC)和质谱法(MS)分析其发酵产物,其紫杉醇产量为2.5～3.0μg/g(紫杉醇/菌丝干重),并通过形态学特征和18 S rDNA序列分析,将其初...从曼地亚红豆杉(Taxus x media)树皮内表皮中分离得到1株产紫杉醇的内生真菌O60B1,并通过高效液相色谱法(HPLC)和质谱法(MS)分析其发酵产物,其紫杉醇产量为2.5～3.0μg/g(紫杉醇/菌丝干重),并通过形态学特征和18 S rDNA序列分析,将其初步鉴定为毛霉属(Mucor sp.)真菌。展开更多
