Cucurbita (Cucurbitaceae). C. pepo ( pumpkin) germ. 70L(85% in 4-14 d) and 70D(none). The results were the same whether the seeds were just rinsed or WC for 1 d. The seeds die rapidly if kept under water and germ. 70L(10% on 8th d) after 17 d under water. The light requirement dies off with DS, and seeds DS 6 m germ. 100% in 70Ó. Presumably lack of access to oxygen is a factor in blocking germination of the seeds inside the fruit.
