猕猴桃果实不同部位间果实品质的差异性分析

为探究猕猴桃果实不同部位间主要果实品质的差异,以猕猴桃品种'红阳'金果'金艳'为试材,通过套袋和未套袋处理,测定其果实不同部位间主要果实品质并进行差异性分析。结果表明:不同猕猴桃品种间果实主要品质存在较大差异,同一品种其果实不同部位的主要果实品质也存在较大差异;未套袋处理的'红阳'果实以其上部(果基)综合品质最佳,'金果'为下部(果顶),'金艳'为中部;套袋处理后,'红阳'以果实中部综合品质最佳,'金果'为上部,'金艳'为下部。据此,在对果实品质进行测定时,建议各部位均匀混合取样或者取相同部位的样品;套袋试验结果表明,套袋能增加'金果'猕猴桃干物质含量,提高'金艳'猕猴桃采摘期外果皮的硬度,且能促进'金果'和'金艳'猕猴桃软熟期的着色。

Difference Analysis on Fruit Quality Among Different Parts of Kiwifruit

In order to investigate the difference of main fruit quality between different parts of kiwifruit,the main planting materials,‘Hongyang’‘Jinguo’‘Jinyan’ were treated by bagging and unbagging.The main fruit quality of different parts of the fruit was determined and the difference was analyzed.The results showed that there were great differences in main fruit quality among different kiwifruit varieties,and there were also great differences in main fruit quality in different parts of the same variety.In the absence of bagging treatment,‘Hongyang’ had the best comprehensive quality inthe middle of the fruit,‘Jinguo’had the best comprehensive quality in the top of the fruit,and‘Jinyan’has the best comprehensive quality in the bottom of the fruit.After bagging treatment,the best comprehensive quality in the middle of the fruit was‘Hongyang’,the top of‘Jinguo’,the bottom of‘Jinyan’.Therefore,in the determination of fruit quality,it was suggested that all parts should be mixed evenly or take samples from the same parts.The results of bagging test showed that bagging could increase the dry matter content of ‘Jinguo’,increase the hardness of exocarp during picking period of‘Jinyan’,and promote the coloring of‘Jinguo’and‘Jinyan’kiwifruit at soft ripening stage.
