摘要
通过对加工桃果实采前30d喷钙处理,研究不同浓度钙处理对贮藏期间加工桃果实生理和品质变化的影响。结果表明,采前喷施不同浓度的钙处理均能够抑制细胞膜透性的增大,降低呼吸强度和乙烯释放量,抑制多酚氧化酶(PPO)的活性,保持果实硬度和品质。其中,采前喷施1.0%和1.5%钙处理能够明显地提高加工桃果实的硬度,对延缓加工桃贮藏期间果实后熟、减轻果肉褐变和保持果实品质的效果最好。
With pre-harvest treatment of different calcium concentrations, the changes in physiology and quality attributes of peach fruits for processing during storage periods were investigated. The results showed that the calcium treatment with different concentration 30d before harvest decreased the respiration rate and ethylene production, inhibited PPO activity, and maintained fruit firmness and quality. The spraying of 1.0% and 1.5% Ca（NO3）2 is the best effective treatment which significantly improved the fruit firmness, delayed senescence during storage periods, reduced flesh browning and maintained the quality of peach fruits.
