摘　　要：【目的】研究涂膜处理对采后石榴品质和生理的影响,筛选适合石榴贮藏保鲜的涂膜剂,为石榴贮藏提供理论依据及方法。【方法】以皮亚曼石榴和大籽甜石榴为试验材料,采用高分子化合物对石榴进行涂膜处理,贮藏于冷库中,研究涂膜处理对石榴失重率、腐烂率、可溶性固形物、电导率、呼吸强度及乙烯释放的影响。【结果】涂膜处理显著降低石榴贮藏过程中的腐烂率,抑制果实失重及细胞膜渗透率的增加;涂膜处理果实可滴定酸含量显著高于对照,可溶性糖与可溶性固形物含量无显著差异;涂膜处理抑制石榴乙烯的产生速率,对呼吸强度无显著影响。【结论】涂膜处理降低石榴腐烂率,抑制水分蒸发,保持果实品质。[ Objective ] This paper studies the effect of coating - treatment on postharvest qualities and physiology of pomegranate to select the better coating- agent for maintaining qualities during its storage. [Method] Pomegranate fruits were used to investigate the effect of coating - treatment on weight loss, decay rate, soluble solids content, respiration rate and ethylene production during low temperature storage. [ Result] The coating - treatment could effectively reduce the decay rate, inhibit the increasing of weight loss and cell membrane permeability. The coating - treated fruits had higher titratable acid content than that of the control, but the soluble solid content didn＇t change significantly. The coating- treatment inhibited the ethylene production rate, and had little inhibition of the fruit respiration during storage. [ Conclusion] Coating- treatment could depress the decay, maintain qualities of pomergranate fruit during cold storage.
