一、目的与材料方法 近年来,网纹甜瓜(Cucumis melo L.var.reticulatus Naud.)的生产在我国已有较快的发展,采后运输和贮藏保鲜等问题需要研究解决。据文献记载,甜瓜果实对低温较为敏感,因此贮藏中的冷害问题极为重要。关于甜瓜果实的冷害温度,因变种或品种不同而报道各异。例如‘Cantaloup’(欧美品种商品名)为 2～5℃;‘Honey Dew’(蜜露甜瓜)为7～10℃;‘炮台红’(哈密瓜品种名)为0～2℃等等。网纹甜瓜的品种类型繁多,但关于贮藏适温及其冷害方面的报道较少。本试验仅就‘87—1号’网纹甜瓜果实在贮藏期间冷害发生的规律进行了初步观察。 试验于1989～1990年进行。供试材料为本所温室春季生产的‘87—1号’网纹甜瓜,于1989年5月23日采收,约八成熟(人工授粉后44～48天),用克霉灵药剂在20℃下薰蒸(杀菌防霉)一昼夜,然后装筐覆盖塑料膜分别入1、4、7、10、13、20±0.5℃库贮藏。每一温度处理30个瓜。定期在各温度下测定呼吸强度和乙烯释放量,调查冷害发生情况。并每 First, the purpose and methods of materials In recent years, the production of muskmelon (Cucumis melo L.var.reticulatus Naud.) Has been rapid development in our country, post-harvest transport and storage and preservation and other issues need to be addressed. According to the literature, melon fruit is more sensitive to low temperature, so the issue of chilling damage in storage is extremely important. On the melon fruit chilling temperature, due to different varieties or reported different. For example, ’Cantaloup’ (European and American brand names) is 2 to 5 ° C; ’Honey Dew’ is 7 to 10 ° C; Forte Red is 0 to 2 ° C and so on. Reticulated melon variety of types, but less storage temperature and cold damage reported. This experiment only on the ’87’ No. 1 ’melon fruit stored in the cold during the occurrence of a preliminary observation. The experiment was conducted from 1989 to 1990. The tested materials were ’87-1’ netted muskmelon produced by our greenhouse in spring and collected on May 23, 1989, about eight mature (44-48 days after artificial pollination) ℃ fumigation (sterilization mold) a day and night, and then covered with plastic film basket into 1,4,7,10,13,20 ± 0.5 ℃ storage. 30 melons per temperature. Respiratory intensity and ethylene release were measured periodically at various temperatures to investigate the occurrence of chilling injury. And each
