摘　　要：软枣猕猴桃为雌雄异株植物,适配雄性品种较少。为探究花粉直感效应对软枣猕猴桃果实品质的影响,科学配置授粉雄性品种,以长江1号软枣猕猴桃为母本,采集20个不同雄株的花粉进行人工授粉,分析长江1号当年坐果率及其果实品质,并基于主成分分析法综合评价其果实品质,筛选适配雄株。结果表明:长江1号软枣猕猴桃存在花粉直感效应,花粉对当年坐果率、单果重、果形指数、可溶性固形物含量、可滴定酸含量、固酸比、维生素C含量、多酚含量、黄酮含量、总氨基酸含量和总矿物质含量存在不同程度的影响,其中黄酮含量可提高103.45%,为影响最显著的指标;编号分别为SNXS005、SNXS003、SNXS020、SNXS014和SNXS017的雄株花期均与长江1号吻合,授粉后当年坐果良好且果实综合品质优异,具有作为长江1号适配雄株的潜力。研究结果可为软枣猕猴桃雄性品种的选育提供科学参考。Actinidia arguta is dioecious plant with few suitable male plants.In order to explore the influence of xenia effect on fruit quality,pollinating male plants were scientifically allocated.Using Actinidia arguta ‘Changjiang1' as the mother,20 different male plants were collected for artificial pollination,the changes of fruit setting rate and fruit quality were analyzed,and fruit quality was evaluated comprehensively based on principal component analysis,and suitable male plants were screened.The results showed that xenia effect on fruit setting rate,fruit weight,fruit shape index,soluble solid content,titrable acid content,solid acid ratio,vitamin C content,polyphenol content,flavonoid content,total amino acid content and total mineral content.The flavonoid content was increased by103.45%,which was the most significant index;the flowering period of SNXS005,SNXS003,SNXS020,SNXS014and SNXS017 male plants were consistent with ‘Changjiang 1',and the contemporary fruit set rate was good and the comprehensive fruit quality was excellent after pollination,which had the potential as suitable male plants for‘Changjiang 1'.This study provides scientific reference for the breeding male plants of Actinidia arguta.
