The reproductive development process of birch was described as follows: Male inflorescences extended from apical bud in early June. In later June, stamen primodium was differentiated in the bract of male inflorescence and the differentiation of bract was generated in female inflorescence. During July, anther layers and archesporial cell were differentiated in anther, then archesporial cell developed into mother microspore cell. Pistil primodium came into being at the same time. In early part of August the meiosis of mother microspore cell started. In later August, mono-nucleus microspore was formed. After September, both male inflorescence and female inflorescence were dormant.

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.

In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.
