1985、1986两年对西瓜采后呼吸强度的变化、贮藏温度对西瓜的影响、品种间耐藏性差异及防腐措施等进行了初步研究。试验结果表明:(1)供呼吸强度测定的郑州3号、中育10号、少籽(黑枚×郑州3号)、中育6号4个品种中,以采收时达9～10成熟的中育10号西瓜采后无明显的呼吸高峰。(2)西瓜贮藏的冷害阈值温度不低于12.5℃。但3.5～12.5℃的低温不伤害瓜瓤品质,因此,建议在西瓜贮运中,应根据不同贮运期及经济效益选用适当的温度。(3)西瓜品种间耐贮性差异显著,在供试的中育10号、丰收2号、蜜桂、新澄、浙蜜、中甘9号、苏蜜、8155、湘蜜及石红1号1个品种中,中育10号、丰收2号及蜜桂品种耐贮性较强。(4)用克霉灵熏蒸西瓜是一种简便易行、安全经济的防腐方法。(陶辛秋等)
In 1985 and 1986, the respiration intensity of postharvest watermelon, the effect of storage temperature on watermelon, the difference of storage resistance among varieties and the anti-corrosion measures were studied. The results showed as follows: (1) Among the three cultivars of Zhengzhou No. 3, Zhongyu No. 10, Xiaowei (Hei Mei × Zhengzhou No.3) and Zhongyu No.6 for respiration intensity, Of the No.10 watermelon postharvest no significant respiratory peak. (2) Chilling injury threshold of watermelon storage temperature of not less than 12.5 ℃. However, the low temperature of 3.5 ~ 12.5 ℃ does not harm the quality of melons, therefore, it is suggested that the appropriate temperature should be selected according to different storage and transportation and economic benefits. (3) There were significant differences in storage resistance among watermelon cultivars. Among the tested cultivars, Zhongyu 10, Fengkeng 2, Miui, Xincheng, Zhemi, Zhonggan 9, Sumei, 8155, Xiangmi and Shihong 1 No. 1 varieties, Zhongyu 10, harvest No. 2 and honey varieties strong storage durability. (4) Ketjidine fumigation watermelon is a simple, safe and economical method of preservation. (Tao Xinqiu, etc.)
