摘要/Abstract

摘要： 通过从采后落粒的葡萄果实上分离的7属病原真菌, 分别回接健康果实的方法, 比较分析了各种病原真菌对果粒脱落的影响。结果表明: 灰霉菌(Botrytis cinerea) 、链格孢菌(Alternaria ssp. ) 和镰刀菌(Fusarium sp. ) 是引发葡萄果实采后落粒的主要病原。通过田间与采后的防菌措施对葡萄采后脱落进行了控制处理, 进一步证明了病原真菌在葡萄采后果粒脱落中的重要作用。

Abstract: Abscission of grape berries during the storage is aserious factor that affects the quality of grape. The abscission is caused physiologically or as a result of the damage from fungal infection. In the present study, some fungi were isolated from grape berries dropped and inoculated into healthy fruits to verify their involvement in the postharvest abscission of grape berries during the storage. Of seven fungi isolated, Botrytis cinerea, Alternaria ssp. and Fusarium sp. were shown to be the pathogens causing the postharvest abscission of
the inoculated berries. Moreover, the fungicide treatment of the postharvest berrieswas effective for preserving the berrieswithout abscission. These results strongly suggest the involvement of some pathogenic fungi in the
postharvest abscission of grape berries during the storage.

Key words: Grape, Abscission, Pathogenic fungi, Postharvest disease, Botrytis cinerea
