| Abstract: | In this paper,.the advances including microsporogenesis, macrosporogenesis, development of female gametophyte, process of fertilization, crossing barriers, development of endosperm and embryo in reproduction biology of poplars were reviewed. And, the emphasis on future research of reproduction biology still focused on the relative domain of crossing and polyploid breeding in poplars is pointed out. Sexual reproduction would steadily develop on human＇s purpose. |
