病原侵染对采后葡萄激素水平的影响

摘要

外源ABA处理采后葡萄可显著促进乙烯释放和抑制IAA的生成,加重葡萄落粒。乙烯利对ABA促进作用不明显,但显著抑制IAA和GA_(3)的生成。葡萄感病后组织内源激素水平发生了变化:ABA含量显著增加,乙烯释放率增大,IAA含量显著减少,这种变化趋势在果梗中尤为突出。

Changes of endogenous hormones in postharvest grape after infected with pathogenic fungi

Abstract

The ethylene evolution rate of grape was markedly intensified while the IAA content in grape was decreased, after the grape was treated by exogenous ABA. Postharvest grape berry drop was promoted by exogenous ABA. It was found that ethephon had little affect on the ABA content in grape, but it inhibited the production of IAA and GA_(3). The ABA content and ethylene evolution rate in grape were markedly increased and IAA content was markedly reduced after the grape was infected by fungi.
