The experiment results showed that the fruiting stage of seed pumpkin (Cucurbita moschata)could be divided into stages of primary, middle and late, which had characteristics of growth and critical peroid, respectively. The increments of leaf areas,fresh and dry weight of fruits and seeds were in a sigmoid pattern of growth.The daily increasing amounts of fruits, seeds and leaf areas were maxium in fruiting middle stage.The weight and volume of fruits increased rapidly in 10 to 15 days after flowering, and the highest level of the dry weight accumulation in fruit was at 30 days after flowring. The most vigorous stage of seed development was during 20 days after flowering. The seeds developed in the most vigorous stage 20 days after flowering.The increasing of leaf areas were tightly related with that of fresh and dry weight (r=0.9849  ,0.9287  ).
