摘要

用光镜和电镜观察了红斑赤眼蜂(Hemigrammus erythrozonus)受精卵包膜的形态和超微结构。受精卵球形、透明、凹陷、粘连，无油滴。卵周空间发育良好，微孔周围有15 ~ 20条凸起的卵包膜，呈辐条状。卵包膜外表面粗糙，有沟槽。受精卵包膜总厚度约为2.1 ~ 2.3?受精卵包膜由两层组成，一层是带凹槽的黏附电子致密层，另一层是3层羽毛状片层。综上所述，受精卵和具有辐状结构的微孔的形态特征具有科特异性，受精卵外表面和包膜切片的超微结构具有种特异性。

Ultrastructure of the fertilized egg envelopes in Hemigrammus erythrozonus, Characidae, Teleostei

We examined the morphology and ultrastructures of fertilized egg envelopes of glowlight tetra (Hemigrammus erythrozonus) belong to Characidae using light and electron microscopes.

The fertilized eggs were spherical, transparent, demersal, adhesive, and have no oil droplet. The perivitelline space was well-developed and the micropyle was surrounded by 15–20 uplifted lines of egg envelope in a spoke like pattern. The outer surface of egg envelope was rough side with grooves. Also, the total thickness of the fertilized egg envelope was about 2.1–2.3?μm, and the fertilized egg envelope consisted of two layers, an outer adhesive electron-dense layer with grooves and three feather-like lamellae layers. Collectively, these morphological characteristics of fertilized egg and micropyle with spoke-like structure showed family Characidae specificity, and ultrastructures of outer surface and section of fertilized egg envelope showed species specificity.
