毛花猕猴桃果实发育过程中理化性质的变化研究
摘要
为深入了解猕猴桃果实生长发育规律及果实商品价值,本研究以四川地区野生毛花猕猴桃果实为材料，采用田间取样和实验室测定相结合的方法测定其果实发育过程中理化性质变化.结果显示果实重量、纵横径和干物质积累呈单‘S’型曲线.果实淀粉积累时间短，果糖和葡萄糖从盛花期（DAA）105 d开始急剧上升，果实成熟时生成少量的蔗糖和麦芽糖.苹果酸和柠檬酸浓度整体呈上升趋势，而奎宁酸在90 DAA前保持相对恒定,105 DAA时下降到最低,后保持稳定.VC含量高，整体呈下降趋势.以上结果说明毛花猕猴桃果树园艺性状好，其果实有机酸含量高，特别是VC，是天然维生素库.

Abstract
In order to further explore the Actinidia fruit development and fruit commercial value, the fruit of a wild A. eriantha (found and cultivated in Sichuan, China) was used as the material to measure the dynamic changes of Physicochemical properties by combining field sampling and laboratory measurement.The results showed that flesh weight, vertical and horizontal diameter, as well as dry matter (DM) accumulation showed a sigmoidal increase trend during the fruit development. The period of starch accumulation was short, fructose and glucose concentration rose sharply after 105 DAA, and a small amount of sucrose and maltose were formed in the fruit physiology mature stages. The concentration of malic acid and citric acid showed an overall upward trend, while quinic acid remained relatively constant before 90 DAA, and rapidly decreased to the minimum at 105 DAA, and then remained relatively stable after words. The VC concentration was high and showed a decreasing trend. The A. eriantha fruit had excellent horticultural characters, and its fruit has a high content of organic acid, especially VC, which was a natural vitamin pool.
