| 摘要: |
| 本文用数值分类的方法对来自我国山西、内蒙古以及青藏高原的共15个两性生殖卤虫品系的卵、无节幼体进行了研究.通过卵和无节幼体的聚类分析,青藏高原卤虫品系和其它品系得到很好的分离.发现青藏高原卤虫品系的卵有三个特征,即卵径大,卵壳厚,卵呈紫红色,这些特征均是对那里高寒环境的适应.研究表明,随着分布区海拔的升高,中国各卤虫品系的卵和无节幼体有增大的趋势.其中西藏拉果错卤虫的卵和无节幼体是世界上所有已知品系中最大的. |

| Abstract: |
| We studied cysts and nauplii of 15 bisexual Artemia strains from Shanxi, Inner Mongonia and Qinghai-Xizang Plateau of China by using the method of numeric taxonomy. Through cluster analysis, cysts and nauplii of Qinghai-xizang Plateau were well separated from other strains. Compared with other strains, cysts of Artemia strains from Qinghai-Xizang Plateau are big, and their shells are thick with the color of purplish red, which are the adaptations to the plateau special environments. Both cyst and nauplius of Lagkor Co are the biggest ever recorded for both bisexual and parthenogenetic species. |
