摘要
猕猴桃魁蜜７９－５于５月中旬坐果，１０月上旬采收。其中果实膨大期为５０～５５ｄ，迅速膨大期约为３５ｄ。白色的果心，黑色的种皮，淡茶栗色的外果皮和淡黄棕色茸毛可作为确定采收期的形态指标。种子成熟半月后是最佳采收期。此时果体密度稳定，果体体积、质量达最大值，可溶性糖１．１９５０ｇ·ｋｇ－１，还原糖３．４３４５ｇ·ｋｇ－１，也是结实期内最大值，蛋白质生成量达６．５％，是第２次峰值，维生素Ｃ虽降至５３２．０ｍｇ·ｋｇ－１，但有机酸总量也降至较低值１．０５％。文中还讨论了果体形态、营养生理代谢、果体生长量、密度变化之间的相互关系。
Kiwiberry Kuimi 79 5 set fruits in mid May and its fruits could be picked in early October The enlarging period of fruits lasted 50～55 d White fruit hearts,dark seed coats and high brown exocarps could be indicators for collection The most suitable period for harvesting was 15 days after seed maturation when the fruits had the maximum size and wight and a stable species gravity,and contained the most soluble sugar of 1 195 0 g·kg -1 and reducing sugar of 3 434 5 g·kg -1 The protein reached 6 5%,and Vitamin C and organic acid went down to 532 0 mg·kg -1 and 1 05% respectively The relations between fruit shape,nutritive metabolism,fruit growth and specific gravity were discussed
