- 摘要:
- 以“密本”鲜嫩南瓜为试材，研究了3、5、7、9、11℃低温贮藏对鲜嫩南瓜生理特性的影响。结果表明：鲜嫩南瓜在3、5、7、9℃低温下贮藏均有冷害发生，贮藏期间冷害指数、失重、细胞膜透性、黄色素及MDA含量均逐渐升高；叶绿素、可溶性蛋白质含量逐渐下降；11℃下贮藏未有冷害发生，生理活动受到明显的抑制，有效维持了鲜嫩南瓜的营养品质。
- Abstract:
- Taking fresh pumpkin as material,the effect of different low temperatures with 3,5,7，9，11℃ on physiology in postharvest during safe storage period were studied.The results showed that the fresh pumpkin chilling injury occured at 3,5,7,9℃.The index of chilling injury，weight loss，cell membrane leakage，flavochrome and MDA content in fresh pumpkin were increased gradually，chlorophyll content and soluble protein content were decreased in the whole storage.There were no chilling injury in fresh pumpkin at 11℃ and the physiological metabolism of fresh pumpkin was obviously inhibited，the nutritional quality was effectively maintained.
