摘　　要：以成熟的‘河套’蜜瓜果实为试材,在自然贮藏条件下,观测果实采后外部形态、营养品质及与果实成熟衰老相关指标变化。结果表明:贮藏2d时,‘河套’蜜瓜果实特有的颜色、风味、质地逐渐形成,并持续至贮藏第6天;之后,随着贮藏时间的延长,果实外观品质显著下降,表现为果面粗糙,香气变淡,质地变软,同时伴有病斑出现,直至贮藏第12天时果肉溃败腐烂。贮藏期间,可溶性固形物、可溶性蛋白质、有机酸含量均呈现先升高后降低的变化趋势;总糖含量较高并呈下降趋势。贮藏期间,果肉硬度呈下降趋势;相对电导率及丙二醛含量呈上升趋势;乙烯表现为单峰变化趋势,在贮藏第10天达到峰值后迅速下降。因此,进行采后生理调控对保持优良果实品质具有重要意义。With post-harvest Cucumis melo L. ＇ Hetao＇ as materials, the changes of external feature, nutritional quality and fruit ripening and senescence related index in post-harvest Cucumis melo L. ＇Hetao＇ stored in natural conditions were studied. The results showed that in natural conditions,the colour,flavor and character built up after stored 2 days in post- harvest fruits. After 6 days, the exterior quality declined, showed rough, thin frangrance, softening and got rot at stored 12 days. Soluble solid,soluble protein and organic acid content showed a trend of decline and then rising. Total sugar content declined and kept higher level. The hardness of pulp declined while the relative electrical conductivity and MDA content increased;Ethylene appeared unimodal curve changes, and declined from 10 days. Therefore, post-harvest physiology regulation was of great significant to maintain good fruit quality.
