摘要
以枣树组培苗及田间苗为试材,利用高效液相色谱法分析了感病株与健康株(对照)内源激素含量水平的差异。结果表明:感病植株内源生长素(IAA)含量明显低于健康植株,内源玉米素(ZT)、赤霉素(GA)、脱落酸(ABA)含量有所提高,且与发病程度呈正相关。同时得出抗病品种较易感病品种健康植株内源游离生长素(IAA)、脱落酸(ABA)含量水平高,玉米素(ZT)、赤霉素(GA)含量水平低,该研究有助于从分子角度阐明病原与寄主植物的互作机制。
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.
