title: [Effect of different plant growth regulators on transplanting survival ratio of Haloxylon ammodendron seedling and parasitic ratio of Cistanche deserticola].
abstract: OBJECTIVE
  To study the effect of different plant growth regulators on the transplanting survival ratio of Haloxylon ammodendron seedlings and parasitic ratio of Cistanche deserticola.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Rooting soaking with PDJ can be used to improve the survival ratio of Haloxylon ammodendron seedling and parasitic ratio of Cistanche deserticola.
