Abstract: Kiwifruits were treated with calcium at postharvest preiod. The changes of ethylene production, respiratory rate and peroxidase (POD) activity of fruits were determined in order to find out an optimum calcium concentration to delay the ripening and decaying of kiwifruits. 2% calcium treatment was found to be able to inhibit ethylene production, respiratory rate and POD activity, and thus delayed the decay of fruits.

Key words: Kiwifruit (Actinidia chinensis), Calcium treatment, Peroxidase, Respiratory rate, Ethylene

摘要： 对中华猕猴桃果实采后进行钙处理,结果表明,适当提高果实钙含量,可以抑制过氧化物酶(POD)活性,降低呼吸率及乙烯生成量,延缓果实衰老。本实验以2% CaCl₂处理效果最佳。
