拟目乌贼的胚胎发育OA北大核心CSCDCSTPCD
The embryonic development of Sepia lycidas
采捕野生拟目乌贼进行室内培育,利用显微成像系统观察其胚胎发育过程.结果表明,拟目乌贼受精卵乳白色,半透明,呈椭圆形,乳头状,一端呈圆环状套住附卵基质,如葡萄般成串有规律地聚集一起.刚产出的受精卵长径为(39.7±1.7) mm,短径为(17.1±1.1) mm,体质量为(4.3±0.2)g.胚胎呈椭圆形,长径(8.85±0.41) mm,短径为(7.74±0.54) mm.在水温为27℃,盐度为30条件下,孵化第10天卵粒变得最小,长径为(27.…查看全部>>
We collected wild Sepia lycidas to cultivate indoors,and observed the embryonic development by using microscopic imaging system.The results showed that the oosperm was milky,translucent,oval,papillary,and one end of the oosperm which was cylindrical ring-shaped trapped to the spawning substrate,such as grape-like gathered together regularly.The length of the primiparous oosperm was (39.7 ± 1.7) mm in long diameter and(17.1 ± 1.1) mm in short diameter,the wei…查看全部>>
