| 摘 要： | 研究产于安徽省滁州市城西水库的滁州鲫是否行雌核发育繁殖.对滁州鲫♀×滁州鲫♂及滁州鲫♀×红鲤♂受精卵进行细胞学研究,结果表明:(1)在刚产出的成熟卵细胞内没有发现极体,在精子入卵约15～16min后(水温为18～20~C),单个极体被排出;(2)在受精卵内,精核保持凝聚状态,没有形成雄性原核;(3)精子入卵20 min后,卵核形成雌性原核,在第一次卵裂前没有观察到雌性原核与呈凝聚状态的精核的融合;(4)同源与异源精子激发滁州鲫卵的发育过程基本相同,异源精子能进入滁州鲫卵细胞并激发卵核形成雌性原核,并进行正常胚胎发育,其鱼苗正常,无畸形和无杂交性状的鱼苗.研究表明,滁州鲫为雌核发育鱼类. |

| Abstract: | The purpose of our investigation was to examine whether the Chuzhou Crucian carp caught from City-west reservoir in Chuzhou City,Anhui Province,would reproduce by gynogenesis.Their spawns were artificially inseminated with milt of Crucian carp and Red carp(Cyprinus carpio L.red variety),and a number of fertilized eggs were studied cytologically before their first cleavages.The results of observation are as follows:(1) No polar body was found in the ripe egg cells just after spawning.About 15 minutes after i... |
