Abstract

Abstract: Calcium at various concentrations was applied to litehee fruits at postharvest.The changes of peptinesterase,polygalacturonase and cellulase activity of fruits were determined in order to find out an optimum calcium concentration to delay the ripening and deeaying of litehee fruits.4%.calcium treatment was found to be able to retard the activity of these enzymes,delay the appearance of peaks of enzyme activity or even disappear,thus delaying the decay of fruits.

Key words: Calcium, Litchee fruit, Pectinesterase, Polygalacturonase, Cellulase

摘要： 用不同浓度的Ca(Ⅱ)对荔枝果实采后处理,测定果实中的果胶酯酶、多聚半乳糖醛酸酶和纤维素酶的活性变化,发现用4%的钙处理,对上述各酶活性都有一定的抑制作用;在冷藏条件下,还能推迟这三种酶活性高峰的来临,甚至使之不出现,从而延缓了果实的衰老。
