摘要

葡萄采后施用外源ABA可显著刺激其呼吸速率和乙烯释放率,ABA对呼吸的促进作用大于C_(2)H_(4);当葡萄被交链孢和灰霉葡萄孢侵染后,呼吸和乙烯释放均加强。交链孢侵染的葡萄呼吸速率在孢子形成后2d达最大值,而灰霉葡萄孢侵染的葡萄呼吸速率在孢子形成时即达最大值。葡萄感病后,落粒现象加重,组织内源ABA和C_(2)H_(4)含量增加,IAA和GA_(3)含量减少。

Abstract

The respiration and enthylene evolution rates in harvested grapes were markedly stimulated by exogenous ABA, and increased after being infected by fungi. The respiration rate stimulated by ABA was higher than that by C_(2)H_(4). The levels of endogenous ABA and C_(2)H_(4) in grapes were increased and those of endogenous IAAm GA_(3) decreased after the grapes were infected by funqi.
