| 摘 要： | 采用聚丙烯酰胺凝胶垂直平板电泳技术对青岛汇泉湾大叶藻种群内部的遗传多样性进行了初步分析，共研究了6种酶，得到该种群多态位点的比例（P％）为56．52％，每个位点平均等位基因数A／L为1．3478，根据其中17个位点，25个等位基因得到平均杂合度的预期值He为0．2122，观测值Ho为0．3251，对其遗传偏离进行D测验表明，大叶藻的杂合度较高，属于遗传多样性较为丰富的物种。

| Abstract: | Vertical PAGE method was used here to study the genetic diversity of a geographic population of Zmarina Linn.from HuiQuan bay of Qingdao.Six kinds of Isozyme (EST,PRX,GDH,ACP,ALP,OX) were studied and the experimental results showed that: (1) Persent polymorphic loci(P%) was 56. 52%; (2)Average number of alleles per locus(A/L) was 1. 347 8, (3) Average observed heterozygosity (Ho) was 0. 325 1,average expected heterozygosity (He) was 0. 212 2 (17 loci, 25 alleles). D-testing showed that averaged heterozygosity of Zmarina Linn. was comparatively high, and it was rich in genetic diversity. |
