摘要
以早熟梨品种葫芦梨和七月酥、中熟品种鸭梨和黄梨为试材,比较并分析了梨果实发育过程中糖分的变化。结果表明:果实生长发育早期和中期蔗糖几乎没有,只是在成熟前的短期内才完成积累;早熟梨品种的还原糖含量处于持续上升状态而中熟品种在成熟期前2周达到最高峰,之后略有下降;早熟品种梨的总糖含量自始至终处于持续上升状态,而中熟品种的总糖含量在果实发育前期和中期一直处于上升状态,在成熟前2周达到积累高峰,之后略有回落,早熟品种葫芦梨和七月酥、中熟品种鸭梨和黄梨均以积累还原糖为主。
At various developmental stages, sugar accumulation were comparatively studied between early and middle ripening on the different pears （the early ripening：Gourd and Qiyuesu; the late ripening： Yali and Huangli）. The results showed that the early and middle development stage,there were little sucrose, but the contents of sucrose quickly raise at the ripening stage;The reducing sugars of early ripening pears increased all the time, but the middle ripening pears reducing sugars contents were highest 15 day before the ripening stage and decreased at the ripening stage;The total sugar contents of the early ripening pears increased continuously at all the developmental stage, but the middle ripening pears increased at the early and middle development stage, there were highest 15 day before the ripening stage and decreased at the ripening stage. In both pears, fruit accumulated more reducing sugars than sucrose.
