摘要
目的:通过对不同品种的猕猴桃进行根施不同浓度的亚硒酸钠水溶液,研究外源硒处理对不同品种猕猴桃果实性状及硒含量的影响。方法:对9个品种猕猴桃分别进行3个含亚硒酸钠水溶液处理,亚硒酸钠浓度分别为:10mg/L(T1)、50mg/L(T2)、100mg/L(T3),于果实成熟期每株随机采10个果实于常温环境中保存,进行果实性状及硒含量的测定。结果:3个不同浓度的亚硒酸钠水溶液处理,9个品种猕猴桃单果重量、果实纵横径均显著增加,但对果实果形指数没有明显影响;在3个不同浓度硒处理中,100mg/L亚硒酸钠根施处理的猕猴桃果实综合品质最佳。结论:适当浓度的硒处理可以使猕猴桃可溶性固形物含量增加,提高维生素C含量,改善猕猴桃果实内在品质,提高固酸比,改善果实口感。
【Objective】Different varieties of kiwifruit were applied with different concentrations of sodium selenite aqueous solution to study the effects of exogenous selenium treatment on the fruit characteristics and selenium content of different varieties of kiwifruit.【Method】Totally 9 varieties of kiwifruit were treated with 3 aqueous solutions containing sodium selenite,and the concentrations of sodium selenite were 10mg/L(T1),50mg/L(T2),100mg/L(T3),respectively.Totally 10 fruits were randomly selected from each plant at the fruit maturity stage and stored in room temperature environment,and the fruit traits and selenium content were determined.【Result】Three different concentrations of sodium selenite aqueous solution significantly increased the weight and diameter of 9 varieties of kiwifruit,but had no significant effect on fruit shape index.Among the three different concentrations of selenium treatment,100mg/L sodium selenite root treatment of kiwi fruit comprehensive quality is the best.【Conclusion】Proper concentration of selenium treatment can increase the content of soluble solid,increase the content of vitamin C,improve the internal quality of kiwi fruit,improve the ratio of solid acid and improve the taste of fruit.
