摘要/Abstract

摘要： 为探讨钙元素对桃果实品质、耐贮藏性的影响,确定最佳的叶面喷施钙元素的浓度,研究了喷施钙后,桃果肉组织中钙元素的分布特征、叶片叶绿素的含量以及对果实可溶性固形物含量(SSC)、大小、硬度和耐贮藏性的影响。结果表明,果肉中Ca2 的含量随着喷施钙元素浓度的提高而增加,当喷施CaCl2浓度为0.5%时叶绿素的含量最大,当喷施CaCl2浓度为1%时,SSC、果实大小和果肉硬度达到最大值；当喷施CaCl2浓度为2%时,放置3天后果实硬度最大。本研究确立了最佳的喷施浓度,为深入研究果实钙离子浓度梯度在果实品质形成方面的作用提供了依据。

Abstract: To address the effect of calcium element on peach fruit and keeping quality, and establish the optimum leaf spraying concentration, we investigate the calcium distribution in fruit flesh, leaf chlorophyll content, and its effect on SSC, weight, size, flesh firmness and keeping quality of fruit. The results indicate the content of Ca2 in flesh increase with the spraying concentration of calcium. The concentration of Ca2 in flesh is positive consistent to the change of spraying level. The Chlorophyll content is up to the highest lever when spraying 0.5% CaCl2, while the SSC, fruit size, fruit firmness and storage quality are up to the maximum when spraying 1.0% CaCl2. In addition Spraying 1.5% CaCl2 is benefit to the fruit firmness after storage for 3 days. In the Present study, we established the appropriate spraying concentration of CaCl2, and the result will provide information for investigating the effect of Ca2 on fruit quality.
