自由生活海洋线虫Chromadorinasp.的生活史研究
LIFECYCLE OF FREE-LIVING MARINE NEMATODE CHROMADORINA SP1

摘要: 线虫种类繁多、分布广泛、数量极丰富,已鉴定的种类有2万多种,据估计其种类约在4万至1千万种之间[1]。秀丽隐杆线虫(Caenorhabditis elegans)因易于培养、生活周期短、细胞结构简单等,被广泛地用作生物学和毒理学研究的模式生物[2)3]。1990年,Williams等将C1elegans应用于水域、土壤环境的毒理学研究中[4],Tominaga等提出了以C1elegans为模式生物筛选苯酚类和合成激素毒性和激素活性大小的简便实验系统[5)7]。但是,应用海洋线虫进行毒理学的研究报道还很少,海洋线虫个体小,世代时间短,易于实验室培养,是海洋生态毒理学研究的理想实验材料。因此,本文选择青岛栈桥附近分离出来的自由生活海洋线虫Chromadorina sp1为研究对象,研究了其生活史,为今后生态毒理学实验研究提供基本参数。
