摘要
Taxus plants were a kind of important vegetative resources due to that their bark and leaves contain an effective anticancer component taxol. It is very necessary that Taxus planting base was set up,because Taxus population was rare in the natural communities. The cuttings of annual twigs of Taxus mairei without any hormone treatment grow out roots slowly,more than 5 months after have being cut,and their rate of growing roots is lower,only about 30%. In contrast,the cuttings treated with 100～200 mg·L -1 of rooting powder ABT 1 and ABT 2 can significantly increase 12%～14% of survival rate,83%～98% of rooting rate (percentage),more 60%～107% of rooting number and 60%～103% of total rooting length per rooting cutting.
