摘要/Abstract

摘要： 以印度南瓜和中国南瓜为试材，研究了果实发育过程中肌醇、多糖和还原糖含量的变化。结果表明：不同南瓜品种果实中肌醇、多糖和还原糖的含量随着果实的生长发育逐步增加，肌醇含量，印度南瓜在果实发育45 d 时达到峰值，中国南瓜则在35 d 时达到峰值，此后含量均逐步下降；多糖含量，印度南瓜在果实发育55 d 时达到峰值，中国南瓜则在40 d 时达到峰值，此后含量也均呈下降趋势；还原糖含量，印度南瓜在果实发育25 d 时达到峰值，中国南瓜则在35 d 时达到峰值，随后含量均逐步下降；各品种果实均在采收贮藏10 d 时还原糖含量又开始增加，呈现“升、降、升”的变化趋势；不同南瓜品种果实中肌醇、多糖和还原糖的含量存在差异。

Abstract: Dynamic changes of inositol, polysaccharide, and reductive sugar during the fruit development in four pumpkin varieties 'GD-1', 'Abis’(Cucurbita maxima), 'GD-15', and‘Huanglang’ (Cucurbita moschata) were investigated．The results showed that inositol, polysaccharide, and reductive sugar increased and then decreased during the fruit development. Inositol in Cucurbita maxima and Cucurbita moschata reached its peak at the day 45 and 35 after pollination, respectively. Polysaccharide in Cucurbita maxima and Cucurbita moschata reached its peak at the day 55 and 45 after pollination, respectively. Reductive sugar in Cucurbita maxima and Cucurbita moschata reached its peak at the day 25 and 35 after pollination. However, the reductive sugar started to increase at the day 10 after harvesting, and showed a pattern of increase, decrease, and increase. This study also showed variations for inositol, polysaccharide, and reductive sugar among the varieties tested.

Key words: pumpkin, fruit development, inositol, polysaccharide, reductive sugar, nutrient composition
