| 摘 要： | 【目的】研究福寿螺Pomacea canaliculate卵巢发育各期的主要典型特征。【方法】采用组织切片和苏木精-伊红(H.E)染色法,对入侵生物福寿螺的卵巢发育过程、卵母细胞发育各期的显微形态进行了观察和研究。【结果】根据福寿螺卵巢发育的组织学特征,将其发育过程分为5个时期:增殖期、生长期、成熟期、排放期和休止期。在卵巢发育过程中,卵母细胞发生一系列形态结构变化,最终发育为成熟的卵子。福寿螺卵子的形成依次经过卵原细胞期、卵黄合成前期、卵黄合成后期和成熟期。【结论】研究探明了福寿螺的卵巢为管状分支型腺体,卵原细胞经历了5个发育时期形成了成熟的卵子,并分析了福寿螺强大生殖力的原因。

Histological studies on oogenesis and ovarian development of Pomacea canaliculate |
| |
| Abstract: | Objective] The main typical characteristics of each ovary developmental stage of Pomacea canaliculate were studied .Method]Micromorphology of ovarian developmental process and each stage of oocyte development of invader P.canaliculate were observed using histologic sectioning and hematoxylin-eosin staining methods .Result] The ovarian developmental process of P.canaliculata is divided into five stages including proliferating stage , growing stage , maturing stage , spawning stage and recovering stage , based on different histological characteristics .During ovarian development , ovum forming cells experienced a series of morphological and structural changes , and eventually developed into mature eggs . The formation of P.canaliculata ovum consisted the oogonium stage ,early yolk synthesis stage ,late yolk synthesis stage and maturation stage .Conclusion]The ovarian of P.canaliculata is a tubular branching gland, the oogonium goes through five development stages to form the mature ovum , and the structural and physiological characteristics of its ovarian development provide a basis for high fertility of P.canaliculata. |
