| Taxus chinensis(Pilger)Rehd is a natural medication resistant to cancer and garden plants with tremendous value in the field of economic, society and science. Due to long time dormancy and low propagation rates, There are some difficulty in utilization and rapid propagation.We have researched the distribution, resource and its biological, ecological habit, At the same time, We studied the selection and cutting. The good method of propagation had been achieved.This research got the total resource in Ning-shan country, The distribution character had been cleared out. The standards of selection had been set down and 7 good trees had been got. Its prepared the material for propagation and cultivation. The mechanism about Taxus chinensis(Pilger)Rehd is in severe danger was analyzed, Some strategies had been brought forward.It show from the research on propagation that 20 mg·L-1 GGR6 can improve promote survival rate and growth. Its better than 2.4-D and NAA at the same concentration. The method with GGR6 is not more better more long time, Its reduce when the material was deal in high concentration for long time, The accumulation of GGR6 in plant maybe restrain the growth. Different preceding method influence the function of GGR6, The effect of GGR6 after the spike is disposed with glide is better than the effect of GGR6 after the spike is embed with wet sand. It may reduce the effect of GGR6 after the spike is dealed with Duojunlin before insert. Generally speaking, As the non-hormone, GGR6 can adjust the hormone content in plant, It can improve the synthesize of the relatively hormone, enzyme, amic, hydroxybenzene. It can adjust metabolism, improve the growth and shengthen resistance of plant, It also can improve germination, the survival in cutting and transplant. But these function bring into play only in some condition. So It can be used in practice carefully.
