| 摘 要： | 为探究采前喷施脱落酸(ABA)对欧李果实品质的影响,本研究选择农大6号和农大7号2个欧李品种为试验材料,在喷施不同浓度和不同次数的ABA后测定成熟果实的单果重、可溶性固形物含量、可滴定酸含量、类黄酮含量、总酚含量以及抗氧化能力。结果表明,喷施不同浓度和不同次数的ABA后,农大6号欧李果实可滴定酸含量、类黄酮含量、总酚含量以及抗氧化能力降低,对于可滴定酸含量而言,喷施2次比喷施1次的降酸效果明显,而类黄酮含量、总酚含量以及抗氧化能力受ABA浓度和喷施次数的变化影响不大。各处理下农大7号欧李果实的单果重和可溶性固形物含量均得到了升高,类黄酮含量、总酚含量以及抗氧化能力受ABA浓度和喷施次数的变化影响较大。根据主成分分析进行排名可知,不同浓度不同次数的脱落酸处理后农大6号欧李果实综合评分均低于对照,果实综合品质下降,农大7号欧李果实综合评分均高于对照,当脱落酸浓度为25 mg·L-1,喷施次数为1次时对果实综合品质的提升效果最好。本研究为提升欧李果实品质选取喷施适宜浓度和次数的ABA提供了理论基础。

| Abstract: | In order to study the effects of abscisic acid(ABA) on fruit quality of Cerasus humilis, two cultivars of Nongda 6 and Nongda 7 were used as experimental materials by spraying different concentrations and different times of ABA to determine the single fruit weight, soluble solid content (SSC), titratable acid content (TAC), total phenol content (TPC), total flavonoid content (TFC) and antioxidant capacity. The results showed that the content of TAC, TFC, TPC and antioxidant capacity of Nongda 6 fruit were all decreased by all treatments. For TAC, the effect of decreasing acid was more obvious after sprayed twice than that of sprayed once. However, TFC, TPC and antioxidant capacity were not affected by the changes of ABA concentration and sprayed times. The single fruit weight and SSC of Nongda 7 fruit were increased under all treatments. The TFC, TPC and antioxidant capacity of Nongda 7 fruit were greatly influenced by the changes of ABA concentration and sprayed times. After ranking according to principal component analysis, the comprehensive score of Nongda 6 fruit after different concentrations and different times of ABA treatment was lower than that of control group(CK), and the fruit comprehensive quality decreased. The comprehensive score of Nongda 7 fruit was higher than that of CK. When the concentration of ABA was 25 mg·L-1and sprayed once, the improving effect on fruit quality was the best. This study provided a theoretical basis for selecting the appropriate concentration and times of ABA spraying for improving the quality of Cerasus humilis fruit. |
