摘　　要：为探讨葡萄品种间贮藏特性差异,采用质地多面分析和整果穿刺法对6个葡萄品种(红玛斯卡特、亚历山大、夏黑、红地球、金手指、红宝石无核)的质地参数进行测定分析。结果表明,葡萄不同品种间质地差异显著,夏黑果肉硬度、咀嚼性最大,果肉弹性、内聚性、回复性和果皮韧性均最小;亚历山大果皮强度和果皮韧性均最大;红玛斯卡特果肉内聚性和回复性最大。贮藏过程中葡萄果肉硬度、咀嚼性、弹性、内聚性、回复性和果皮强度逐渐下降,而果皮韧性则呈上升趋势。贮藏14 d时,夏黑果肉硬度、内聚性、咀嚼性和果皮韧性降幅显著大于其他品种;贮藏35 d时,红玛斯卡特果肉弹性、内聚性、咀嚼性、果皮强度、果皮韧性均变幅较小,金手指果肉硬度、咀嚼性、果皮强度变幅较大。综合分析认为,6个葡萄品种中夏黑可短期贮藏,红玛斯卡特更耐贮藏,金手指较不耐贮藏,其他3个品种贮藏特性居中。本研究通过比较6个葡萄品种贮藏过程中质地参数变化差异,为葡萄品种筛选及新品种选育提供了一定的理论依据。In order to evaluate storage characteristics of six grape cultivars,named as Red Alexander,Alexandria,Summer Black,Red Globe,Golden Finger,Ruby Seedless,texture profile analysis and whole-fruit puncturing test were used for the texture property analysis during storage. The results showed that texture propertly were significant different among six cultivars. Summer Black had the highest hardness and chewiness,along with the lowest springiness,cohesiveness,resilience,and skin toughness. The highest skin hardness and skin toughness were found in Alexandria,however the highest cohesiveness and resilience was found in Red Alexander. During storage,the hardness,chewiness;springiness, cohesiveness, resilience, and skin hardness were decreased; however, skin toughness increased.Hardness,cohesiveness,chewiness and skin toughness of Summer Black decreased more rapidly than those of other cultivars after 14 days of storage. Springiness,cohesiveness,chewiness,skin hardness,and skin toughness of Red Alexander,decreased at a low level,while hardness,chewiness,and skin toughness of Golden Finger decreased remarkably after 35 days of storage. It was concluded that the order of six cultivars by their storage time was as Red Alexander,Alexandria,Red Globe,Ruby Seedless,Golden Finger,Summer Black. The results of this study would be beneficial for grape quality screening and breeding.
