苹果采后软化过程中糖类物质代谢的研究进展

Research Progress of Sugar Metabolism in the Process of Post-harvested Apple Softening

苹果果实的后熟软化是一个复杂的生理过程,受多种因子调节。本文综述了细胞壁多糖在软化过程中的代谢变化和它对果实后熟软化生理的重要调节作用;可溶性糖和淀粉的代谢变化不仅对于果实风味品质的形成有重要作用,更是维持果实细胞膨压的重要因素,可能是果实软化的另一个关键因素。

The fruit ripening and softening of apple is a complex physiological process,which is regulated by a number of factors.Metabolic change of cell wall polysaccharides during softening and its important role in regulating fruits＇ softening physiology were analyzed.Metabolic changes of soluble sugar and starch played a crucial role not only in the formation of fruit flavor quality,but also in cell turgor pressure maintenance,and may be another key reason for fruit softening.
