| Abstract: | The sexual polymorphism on the levels of organ, individual and population is discussed synthetically. Systematic grading distribution of sex for seed plants, gender plasticity and the cause leading to sex reversion are all introduced. Furthermore, the difference and similarity between angiosperm and gymnosperm in sex types and reproductive system are compared, and the developing trend of spermatophyte studies on sex is prospected from points of view of individual development and system evolution. |
