Abstract:
Taking tissue culture seedling and field seedling of Ziziphus jujube as materials，the variations of endogenous hormone levels in Ziziphus jujube which associated with susceptible and healthy plants were measured using HPLC.The results showed that the IAA level of diseased jujube was much lower than that of healthy ones，on the contrary，the ZT，GA，ABA level were much higher than healthy plants，and was positively related with the degree of disease.And at the same time，the IAA，ABA levels of jujube which were easily associated with susceptible were higher than the resistant ones，and the ZT，GA levels on the contrary.The study was helpful to illustrate the mechanism of pathogeny and autoeciousness plants through molecule aspect．
