光照强度对甜瓜果实糖分积累的影响
Effects of light intensity on sugar accumulation of melon fruits
摘要
Abstract
Three cultivars of Cucumis melo L. Were used to study the effects of light density on sugar accumulation of melon fruits. The results indicated that the glucose and fructose of melon increased quickly at early stages of fruit de-velopment , while sucrose rapid accumulation took place at later stage. When maturing, the sugar content of Yujinxiang (136.63 mg/g) was significantly higher than that of Yindi (119.9 mg/g) , and that in Yindi was clearly higher than that in Huanghemi (108.14 mg/g) . The sugar contents at different fruit points in ripen melon was blossom end > central flesh > stem end. Under shading conditions, the soluble sugars (mainly sucrose) accumulated in melon fruits decreased and the rapid accumulation of sucrose was delayed, whlie the accumulation mode of fruit sugar was not significantly affected. The sugar content reduction in large fruited cv. Huanghemi was higher than those in middle fruited cv. Yindi and small fruited cv. Yujinxiang. These results imply that the sugar content of melon fruits depends on the supply level of assimila-tion .关键词
