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.
