摘　　要：以“红香栗”、“黄狼”、“蜜本”南瓜为试材，对花后果实1～8周期间己糖、蔗糖、β-胡萝卜素、淀粉及五碳糖等营养成分含量的变化规律进行了研究．结果表明，随着果实的生长，蔗糖、β-胡萝卜素、淀粉含量均增加，但不同阶段各品种增加幅度不同；己糖总量下降，但在果实成熟前又稍有上升；部分营养成分含量之间的变化存在着一定的相关性．The change regularity of the nutrient component content was studied in hongxiangli, huanglang and miben pumpkin varieties during 1 -8 weeks after pollination, including hexose, sucrose, β-carotene, starch, pentose and so on. The results indicated that the content of the sucrose, β-carotene, starch all increased, though differently at different growth stage with the fruits growing; and the total hexose decreased at harvest time but increased before maturity. The changes of some nutrient contents had certain correlation.
