| 摘 要： | 利用组织学和超微结构方法,对大连黄海海域的繁茂膜海绵(Hymeniacidonsp.)在自然海域的生长和生殖过程的组织学特征进行了近2a的观察。结果表明:繁茂膜海绵的生长呈现周期性变化,分为4个阶段:复苏期(3～5月)、生长旺盛期(6～8月)、衰退期(9～11月)和冬眠期(12月—次年2月)。繁茂膜海绵可以通过有性生殖进行繁殖,显著生殖期为8～10月,期间可以观察到卵细胞、精细胞囊、胚胎和幼虫。研究结果为深入研究繁茂膜海绵自然生长生殖特点,进而实现海绵组织块的继代培养和人工育种提供实验依据。

| Abstract: | The life cycle(growth and reproduction) of Hymeniacdidon sp. grown in Yellow Sea(Dalian,China) was studied systematically over 22 months using the histological method with light microscope.The result highlighted that Hymeniacdidon sp. is a typical seasonal species with four different developmental stages: resuscitation(March to May),bloom(June to August),decline(September to November) and dormancy(December to February) during its annual life cycle.The reproductive cycle of Hymeniacdidon sp. is mainly from August to October,and all the reproductive elements(oocytes,sperm cysts,embryos and larvae) can be observed.This study documented histological characteristics of the reproductive cycle of Hymeniacdidon sp. ,which will contribute valuable experimental data for the development of sustainable cultivation of explants under controlled conditions and sponge seed-rearing technology for sponge farming. |
