摘要： 以硬肉桃新品种‘双久红’和常规品种‘川中岛白桃’（对照）果实为试材，分别对两品种果实成熟前后20d内的果实硬度、MDA、相对电导率及ABA、GA含量进行了测定。结果表明，自成熟前15d开始，‘双久红’果实的MDA、相对电导率、ABA含量均极显著低于‘川中岛白桃’的（P <0.01）；而前者的GA含量则是极显著高于后者（P <0.01）。相关性分析表明，两品种桃果实硬度与MDA、相对电导率、ABA含量呈极显著负相关（P <0.01）； 而GA含量与前者呈极显著正相关，与后者仅达到显著正相关水平（P <0.05）。

Abstract: Peach fruits of ‘Shuangjiuhong’ and ‘Kawanakajima Hakuto’ (control) were used to study the effects of MDA、relative conductivity、ABA and GA contents related to fruit firmness during 20 days before & after ripening. The results showed that MDA content、relative conductivity and ABA content of ‘Shuangjiuhong’ were significantly lower than these of ‘Kawanakajima Hakuto’ (P<0.01); however, GA content of the former was significantly higher than that of the latter since the 15th day before ripening (P<0.01). Correlation analysis showed that it was fearfully marked negative correlation among the fruit firmness, MDA content、relative conductivity and ABA content in two cultivars (P<0.01)；it was fearfully marked positive correlation between the fruit firmness and GA content in ‘Shuangjiuhong’, and marked merely positive correlation between the fruit firmness and GA content in ‘Kawanakajima Hakuto’ (P<0.05).
