To study the effect of different plant growth regulators on the transplanting survival ratio of Haloxylon ammodendron seedlings and parasitic ratio of Cistanche deserticola.
Different combinations of PDJ and rooting powder were used for rooting soaking with Haloxylon ammodendron seedlings, then the survival ratio of Haloxylon ammodendron and parasitic conditions of Cistanche deserticola were statistical analyzed by SAS software.
PDJ had promotable effect on the inoculating survival ratio of Haloxylon ammodendron and the parasitic ratio, parasitic number and size of Cistanche deserticola, but had no significant effect on the transplanting survival ratio. High concentration of PDJ (1 x 10(-5) mol/L) and rooting powder treatment improved the inoculation survival ratio, and low concentration of PDJ (1 x 10(6) mol/L) treatment improved the parasitic ratio of Cistanche deserticola, but PDJ with rooting powder treatment had inhibitive effect on the parasitism of Cistanche deserticola. Principal component analysis showed that the transplanting survival ratio, inoculating survival ratio, parasitic ratio and the parasited number of Cistanche deserticola could be taken to evaluate the effect of different plant growth regulators, and the comprehensive effect was the best with PDJ treatment.
Rooting soaking with PDJ can be used to improve the survival ratio of Haloxylon ammodendron seedling and parasitic ratio of Cistanche deserticola.
研究不同植物生长调节剂对梭梭幼苗移栽成活率及肉苁蓉寄生率的影响。
采用PDJ与生根粉的不同组合对梭梭幼苗进行浸根处理，然后用SAS软件对梭梭的成活率及肉苁蓉的寄生情况进行统计分析。
PDJ对梭梭接种成活率及肉苁蓉的寄生率、寄生数量和大小有促进作用，但对移栽成活率无显著影响。高浓度PDJ（1×10⁻⁵mol/L）与生根粉处理提高了接种成活率，低浓度PDJ（1×10⁻⁶mol/L）处理提高了肉苁蓉的寄生率，但PDJ与生根粉处理对肉苁蓉的寄生有抑制作用。主成分分析表明，梭梭移栽成活率、接种成活率、肉苁蓉寄生率及寄生数量可用于评价不同植物生长调节剂的效果，PDJ处理综合效果最佳。
用PDJ浸根可提高梭梭幼苗成活率及肉苁蓉寄生率。
