| 摘 要： | 介绍了果实成熟衰老过程中呼吸作用、乙烯释放量、细胞壁超微结构和组分变化,以及与果实软化有关的细胞壁酶的活性变化。多数果实软化是由于细胞壁的破坏,细胞中的果胶溶液化,纤维素解体等。与果实软化相关较为密切的4种细胞壁酶:多聚半乳糖醛酸酶(PG)、β-半乳糖苷酶(β-Gal)、纤维素酶(Cx)和果胶甲酯酶(PME)。为深入研究果实软化机理提供参考。

| Abstract: | The subject describes the changes of the fruits in ripening and senescence,including respiration and ethylene production,the changes of ultrastructure and composition of the cell wall and the enzyme activity with the fruit softening.Most fruit softening is due to the destruction of the cell wall,the solution of pectin in cells and cellulose disintegration.This paper introduces four hyduolytic enzymes which are closely associated with fruit softening: polygalacturoneses(PG),β-galactosidase(β-Gal),cellulase(Cx) and pectinmethylesterases(PME),in order to provide a reference for the mechanism of fruit softening in the future. |
