摘  要：
作者对海蛰卵巢进行了解剖、组织切片与扫描电镜观察,发现卵巢为褶叠型,一端与胶质膜相连,另一端游离。胶质膜由透明状胶质细胞所构成,外有一层纤毛细胞,靠近胶质膜一侧的卵巢为单层上皮组成的生殖上皮,胶质膜与卵巢生殖上皮间由胶质细丝连接,形成与胃腔相通的生殖腔隙。生殖上皮在生殖季节中变化很大,它首先完成发生卵原细胞的功能,随后局部解体出现透明小区,当卵巢成熟时生殖上皮细胞是区域性弥散,卵子裸露,出现分批排卵现象.海蛰排卵方式是以大量卵子成片分批区域性排放为主,但也存在单个卵子排出的现象。

摘  要：
The ovaries of edible medusa(Rhopilema esculenta) were diassectedand observed by histological sections and scanning of E. M. It was discovered that theovary is fold-type. It′s one side connects with gelatinous membrane while the otherside is isolated. Gelatinous membrane is a single layer of ciliated cells, on the outerconsists of spongiocyte. On the side of gelatinous membrane of ovary is one layer ofepithelium which made up of germinal epithelium. The gelatinous membrane andgerminal epithelium connect by colloid fine filaments. Germinal epithelium varies greatyl in spawning season.It accoplishes the func-tion of oogensis at first and gradually dissolves into hyaline little area thereafter. During maturation of the ovary germinal epithelium diffuses locally and the round,oval ova becomes caked. A great deal of ovum discharged in hatches, it is the maintype of ovulation in edible medusa, but diecharge of single ovum also exists.
