Abstract and SummaryThe crude fat content of whole seed and the crude protein level of defatted embryos were monitored on successive days after pollination. Seed of Buffalo gourd,Curcurbita foetidissima HBK, harvested during September–October, 1976, obtained a maximum oil and protein level in 38 to 42 days after pollination. Maximum protein and oil accumulation in seeds of theCucurbita digitata group (sample period June–July, 1976) andApodanthera undulata (sample period August–September, 1976) occurred between 34 and 38 days and 30 and 34 days after pollination, respectively. Variability within sample periods was attributed to the heterogeneity of the populations.
