1.ON ANNUAL CHANGES IN THE TESTES OF MATURE ILISHA ELONGATA (BENNETT) OF THE EAST CHINA SEA
2.The expression of vasa mRNA in mature testis is restricted to the spermatogonia and spermatocytes.
3.The Establishment of Cell Lines From Spermary of Philosamia cynthia
6.Testis squash technique was used for preparation of chromosomes and method of BSG (Barium hydroxide / Saline / Giemsa) was adopted for C-banding staining.
7.A hermaphroditic reproductive organ that produces both sperm and eggs, found in certain gastropods.
8.The result showed that the spermary under 0.05% colchicum for 6-10 hours pretreatment, 0.4% KC1 solution for 45minutes to get the low osmosis, and Giemsa dyed for 10-20 minutes, the clear and separated chromosome can been observed.
9.In male crab, hemolymph T level began toraise in October and reached to2.15±0.28ng/ml in December, it induced the development and maturation oftestes.
10.The results showed that the gametogenesis of Yellow sea bream could be divided into five phases and gonad development could be correspondingly divided into six stages. The GSI of ovary at Ⅴphase was 7.60%～13.30%,with average 9.45%,while GSI of spermary atⅤphase was 1.62%～2.71%,with average 1.99%.
