摘要: 对梅果采后及采后不同处理后的细胞超微结构进行了观察,发现采后梅果叶绿体数量由多变少,有色体出现,线粒体降解,液泡破裂,胞间层增溶,微纤丝排列松懈,最终导致果实的软化。20mg/L GA3、2%CaCl2、1.0g/kg 乙烯吸收剂处理有利于维持果实胞间层和液泡结构完整,热空气2d处理对细胞质的影响大于细胞壁。

Abstract: Cell ultrastructure of postharvest green mume being both treated and untreated were investigated.Reduction in chloroplast,appearance of chromoplast,degradation of mitochondria,rupture of vacuole,dissolution of middle lamella and relaxation of microfiber array caused the in softening of the fruit.The treatment of 20mg/L GA3,2%CaCl2 and 1.0g/kg ethylene absorbent aided in keeping middle lamella and vacuole intact respectively,while hot air 2d treatment had more effects on cytoplast than on cell wall.
