在自然界中大多数植物是雌雄同株的。在一朵花中雄蕊和雌蕊的繁殖器官并存,这叫做雌雄同株。雄蕊产生花粉,雌蕊有子房,受粉后形成果实和种子。但也有少数植物雌雄蕊并不同株,这叫雌雄异株。雌雄异株的植物性别是受遗传基因支配的,一种基因型形成雄株,另一种基因型形成雌株。最近国外科学家发现,世界上有50多种雌雄异株的植物是可以改变性别 Most plants in nature are monoecious. In a flower stamens and pistils reproductive organs co-exist, this is called monoecious. Stamens produce pollen, pistils ovary, after the formation of fruit and seed powder. But there are also a few plant stamens and different strains, called dioecious. Dioecious plant sex is governed by genetic genes, one genotype forming the male and the other genotype forming the female. Recently, foreign scientists found that over 50 dioecious plants in the world can change their sex
