中文摘要：

研究了金艳猕猴桃似ctinidtachinensis×A．eriantha）4个不同采收期（I-IV）在常温[（23±1）oC]贮藏60d，以及低温（4℃）贮藏2、4、6个月后常温货架14d内果实品质和果肉色彩的变化。结果表明：采收期I和Ⅳ的果实在常温贮藏过程中呼吸高峰出现早、失重快，可滴定酸（TA）、维生素c（vc）含量和果肉硬度迅速下降；而采收期Ⅱ和Ⅲ的果实呼吸高峰出现晚，保持了较高的TA、vc含量和果肉硬度。4个采收期猕猴桃果实在常温贮藏期间，果实亮度p、色度C^＊和色彩角h显著降低；而在低温贮藏后常温货架期间，果实色彩角h相对于亮度L^＊和色度C^＊变化更加明显。研究表明，采收期Ⅱ和Ⅲ为金艳猕猴桃的适宜采收期，色彩角h可以作为适宜的指标反映猕猴桃果实的后熟与衰老，而低温贮藏6个月金艳猕猴桃仍能保持较好的食用品质和色彩。

英文摘要：

The changes in quality and flesh color of＇ Jin Yan＇ kiwifruits were investigated. ＇ Jin Yan＇ kiwifruits （Actinidia chinensis x A. ericantha） were harvested at four different times, and stored for 60 days at （23 ± 1 ） ℃ and for 2, 4, 6 months at 4℃, respectively, before maintained for 2 weeks at ambient temperatures [（23± 1）℃ ]. The results showed that the respiratory peaks of fruits harvested at Ⅰ and Ⅳ stages were earlier than those of fruits harvested at Ⅱ and Ⅲ stages, and the fruit weight loss were also faster, as well as the titratable acidity （TA）, vitamin C （Vc） content and flesh f＇wrnness rapidly decreased. Fruit lightness （L^＊）, chroma （C^＊） and hue angle （h） in fruits of the four harvest stages decreased significantly during ambient storage, nevertheless h changed more obviously than L^＊ and C^＊ in fruit maintained for 2 weeks at ambient temperature after cold storage. It suggested that the harvestⅡand Ⅲ stages were suitable for harvesting of ＇ Jin Yan＇ kiwifruit, and h could be used as an appropriate indicator of ripening and senescence of kiwifruit. In addition; edible quality and flesh color of ＇ Jin Yan＇ kiwifruit were well maintained even after cold storage for 6 months.
