摘要:
以新疆古尔班通古特沙漠南缘3条典型沙漠公路两侧的羽毛针禾(Stipagrostis pennata)为研究对象,利用17对微卫星标记(又称为简单重复序列,简称SSR),探讨公路对阜康、沙湾和148团3个种群基因流的影响。单因素方差分析结果表明,平均等位基因数、有效等位基因数、Shannon多样性指数、观测杂合度、预期杂合度和Neis多样性指数在阜康种群和148团种群间整体上存在显著差异,在阜康种群和沙湾种群间均不存在显著差异,在沙湾种群和148团种群间只有观测杂合度存在显著差异,其余遗传多样性指标在沙湾种群和148团种群间均不存在显著差异;遗传分化系数和基因流在3个种群的两两间均存在显著差异。从长远上看,公路对羽毛针禾种群间的基因流起到一定的阻碍作用,此外,种群间的基因流还受到农田开垦和水库修建的影响。
