不同甜瓜品种在采后贮藏过程中生理与品质变化

摘要

The changes in fruit physiology and quality of three melon varieties during storage were studied.The results indicated that there was great difference in the physiology and quality of post-harvest fruits among 3 melon varieties.In comparison with other 2 varieties,Hamilv melon showed better storability during the whole storage: the respiratory peak value of its fruits appeared latest (21 days after harvest);the decrease in its fruit hardness,water content,soluble sugar content,soluble solid content and vitamin C content was the slowest;the decay rate of its fruits was the lowest.Therefore,the fruits of Hamilv melon are suitable for long-time storage.%以3个不同品种甜瓜为试材,研究了其在不同贮藏期间各品种甜瓜果实生理和品质的变化情况,结果表明:不同的甜瓜品种对采后果实的生理与品质影响较大,与其他2个品种相比,哈密绿甜瓜在整个贮藏过程中表现出较好的耐贮性,果实的呼吸高峰值出现最晚,为21 d,果实硬度、含水量、可溶性糖、可溶性固形物和维生素C含量下降速度缓慢,腐烂率最低,适合较长时间贮藏.
