摘要
感染冰核细菌溃疡病的杨树树皮内源生长素(IAA)和玉米素(ZR)含量要高于未被感染的健壮杨树,而感染冰核细菌溃疡病的杨树树皮内源赤霉素(GA4)和脱落酸(ABA)含量要低于未被感染的健壮杨树。内源激素的变化最终导致感染杨树患病部位肿茎形态结构的形成、略变活跃的生理状态以及抗寒能力的降低。
The content of endogenous phytohormone like auxin and zeatin （a kind of cytokinesin） was higher in infected bark than that of in healthy bark, while the content of endogenous giberellin and abscisic acid droped in the diseased bark. The changes of endogenous phytohormone finally resulted in the development of swollen stem, slightly more active physiological state and decrease of the resistance to cold.
