摘要:研究了不同浓度二氧化氯(Cl O_2)对‘徐香’猕猴桃贮藏过程中呼吸及代谢的影响,以期为南方猕猴桃的贮藏提供理论依据和技术参考。以浙江省江山市主产的‘徐香’猕猴桃为试材,分别用0、20、50、80 mg·L^(-1)的二氧化氯溶液浸泡猕猴桃果实20 min,在(3±1)℃条件下贮藏,每隔20 d取样测定其呼吸强度及生理代谢的指标变化。与其他处理相比,50 mg·L^(-1)二氧化氯处理有效抑制了猕猴桃果实的相对电导率和丙二醛(MDA)含量的上升速率,较好保持了超氧化物歧化酶(SOD)和过氧化物酶(POD)的活性,降低猕猴桃的呼吸强度,有效保持了猕猴桃果实的贮藏品质,延缓其后熟衰老速率。
The study researched the postharvest physiology and metabolism of ‘Xuxiang' kiwifruit,and to provide theoretical and technical reference for the south kiwifruit 's storage. The test material was ‘Xuxiang' kiwifruit which planted in Zhejiang province,the chlorine dioxide,which concentrations were 0,20,50,and 80 mg·L^(-1),were used before storage at(3±1) ℃. The kivifruit's hardness,respiratory intensity and physiological metabolism were measured regularly. Compared with the orther groups,50 mg·L^(-1) chlorine dioxide inhibited the relative electrical conductivity and malondialdehyde(MDA) content of kiwi fruit 's,maintained superoxide dismutase(SOD) and peroxidase(POD) activity,hold the espiratory intensity of ‘Xuxiang ' kiwifruit effectively,hold the better quality and postpone its ripening and senescence of ‘Xuxiang' kiwifruit.
