Abstract
With the cultivar of Tianfu 1 as test material,the effects of calcium fertilizers on antioxidant enzymes in apple during storage period were studied.The results showed that there was a temporal synchronization for both the activities of SOD and CAT to reach the peak in fruit stored under 0℃.It suggested that SOD and CAT cooperated as main antioxidant enzymes to protect the cytomembrane system from active oxygen and peroxy radical during the early storage period.After 60 days of storage,the activity of POD significantly increased,and the concentration of MDA also showed the same trend,so POD was the main active enzyme in the late storage stage.The activities of SOD and CAT were significant improved and the concentration of MDA was significant decreased by spraying of calcium fertilizers,in which the effect of functional foliar fertilizers was more effective than that of nutritional ones.The activities of SOD and CAT were the highest under the treatment of amino acid chelate,followed by Handilong humic acid.Therefore,amino acid chelate was selected as the best calcium fertilizer for prolonging fruit storage,and Handilong humic acid was suitable to the orchards in arid areas because of its drought-resistant ability.
