摘　　要：礁膜配子接合及合子的附着以１０￣１２ｈ的黑暗处理为宜。光强对合子的生长发育影响较大，合子早期生长快，适宜光强为３０００￣５０００ｌｘ，合子后期生长减慢，开始转化形成游孢子囊，适当降低光照强度和缩短光照时间有利于游孢子囊的形成和游孢子的放散。这些研究结果将为礁膜人工育苗提供科学依据。Treatment for 10 ￣ 12h by darkness is suitable for the gametogamy and adherence of the zygote of Monostroma nitidum. of light intensity exerts influence on the growth and development of the zygote. In the early stage the zygote grew rapidly, a suitable light intensity was 3000 ￣ 5000lx, but it was slow down in the late stage and the zoosporangium began its formation.Suitably reducing light intensity and shortening the time of light were favourable for the formation of the zoosporangium and the discharge or zoospore.
