The results showed:Seeds yield of seed gourd in the second nodal female flower and its thousand grain weight were higher. With artificial pollination.its mount of seed grain in one seed gourd was more than seedgourd in the first or third nodal female flower 111.4 or 43,andits weight in one seed gourd also increased 56. 9% or 17.0%.
