The result of HPLC to the endogenous hormone in different jujube varieties fore-and-aft inoculated the phytoplasma indicated that the content of IAA in the resistant materials was higher than that in the sensitive varieties and the difference reached significant level,while different resistances inoculated pathogeny contained lesser IAA than the healthy CK and the difference was also remarkable.The content of ZT in the sensitive jujubes was higher than that in resistant species and the difference reached 5% significance.The content of ZT in jujube inoculated was higher than the one not inoculated and the difference reached remarkable level.
