摘要
白骨壤(Avicennia marina)为红树植物。采用垂直板型聚丙烯酸胺凝胶电泳测定了5个白骨壤种群遗传多样性、遗传分化,分析了白骨壤种群的样地气候和土壤理化指标。研究结果表明,环境因子与白骨壤种群的Aat-1A,Aat-1D,Me-1B,Me-1C4个等位基因相关性显著,说明环境因子对这4个等位基因具有选择压力,他们的变化与环境变量有关。
Avicennia marina is mangrove plant. Genetic diversity and genetic differentiation were measured with the assay of vertical slab polyacrylamide gel electrophoresis in Avicennia marina populations. and climate and chem-istry physical as characteristic of soils were analyzed in sampling sites of 5 Avicennia marian populations. The eco-logical analyses of genetic variation and ecological differentiation of Avicennia marina populations were studied. The environmental factors have a significant relation with 4 alleles including Aat-lA,Aat-lD,Me-lB,Me-lC,show-ing that the environmental factors which relate with the alleles have selective pressure on the 4 alleles,and the 4 al-leles varied with the environmental factors.
