雄器

Observing the mature embryo sac of the mutant: It was found thatthe embyo sac appeared in typical polygonum type and more than 90% of the embryo sac hadintegral inner structure. They had egg apparatus, two polar nucleus and three antipodal cells , and their position in the embryonic sac was normal .
