摘  要:
研究不同贮藏温度下甜瓜果实的细胞膜透性变化及K+、Na+和Ca2+的外渗率。结果表明,甜瓜果实在2℃和5℃贮藏条件发生冷害,其细胞膜透性增加,且温度越低增加越大,表明对膜的伤害越严重。K+的外渗率随温度的降低而增大;Na+外渗率随贮藏时间的延长而增加,21d后贮藏温度越低Na+外渗率越大;Ca2+的外渗率极低,且温度和贮藏时间对其影响不大。

摘  要:
Membrane permeability,leakage of K+,Na+ and Ca2+ of Honey Dew,muskmelon stored at different temperatures were investigated.Results indicated that low temperature storage promoted membrane permeability.The leakage of K+ increased with the decrease of temperature,and the leakage of Na+ increased with the increase of storage time and the decrease of temperature after 21d.The leakage amount of Ca2+ was at a low level,and not affected by storage temperature or time.
