摘要研究松属遗传多样性的方法涉及表型、同工酶、染色体、DNA等多层面。 松树表型性状变异广泛，其不同树种不同性状的遗传力（或遗传率）均存在差异。到目前为止，同工酶仍是检测松树遗传多样性的最常用方法，一般而言，松属树种群体内等位酶多样性程度高，群体间分化较低，但各树种的情形也不尽相同。松属树种染色体水平的变异很低，其核型高度一致。核DNA组较一般阔叶树大，遗传多样性丰富，但叶绿体等质体DNA则多样性...
不同地区库蚊复组群体的同工酶遗传多样性研究Genetic Diversity of Isoenzyme in Culex pipiens complex Field Populations Sampling from Distinct Area of China
库蚊复组 遗传多样性 工酶
2008/1/10
摘要采用水平切片淀粉凝胶电泳的方法，对分布于我国5省的8个库蚊复组（Culex pipiens complex）野生群体的遗传多样性进行研究，分析了4个酶系统7个基因座(ME、MDH-1、MDH-2、MDH-3、GPD、EST-2、EST-3)的酶谱资料。结果显示：（1）群体内存在不同程度的遗传变异（He为0.098～0.41）；（2）较低的基因流水平（Nm=0.64）使遗传漂变起主要作用，造成群...

栓皮栎天然群体SSR遗传多样性研究Genetic Diversity of Microsatellites（SSRs）of Natural Populations of Quercus variabilis
栓皮栎 微卫星(SSR) 遗传多样性 遗传分化
2008/1/8
摘要
利用微卫星(SSR)标记对我国4个省内的5个栓皮栎（Quercus variabilis Bl.）天然群体的遗传多样性进行了研究。16对SSR标记揭示了栓皮栎丰富的遗传多样性：等位基因数（A）平均8.4375个，有效等位基因数(Ne)平均为5.9512个，平均期望杂合度(He)0.8059，Nei多样性指数(h)为0.8041。栓皮栎自然分布区中心地带的群体具有较高的遗传多样性，而人为对森...
