摘要
以巨峰葡萄为试材,研究套袋对葡萄果实中糖代谢及转化酶活性的影响。结果表明:套袋果实在发育过程中蔗糖、葡萄糖、果糖含量和转化酶活性变化趋势与对照基本一致。果实成熟后套袋果的可溶性总糖含量明显高于对照。在果实发育前期,套袋明显改变果实中蔗糖的相对含量及酸性转化酶活性。套袋可能主要是通过影响果实发育早期转化酶活性来影响果实糖分积累。
Kyoho grape was used to study the effect of bagging on sugar metabolism and invertase activities. The results showed that sugar contents and invertase activities had almost the same changes as the control berries during fruit development. Compared with the control berries, the total sugar content in bagged berries was significamly higher at the late stage of fruit development. Fruit bagging was shown to change relative sucrose contents and acid invertase activities very greatly. The activities of invertase at the early stage influenced by bagging may be responsible for the accumulation of sugar in the bagged fruit.
