中国北方青杨派杨树遗传多样性研究OA北大核心CSTPCD
Genetic Diversity of Tacamahaca in Northern China
青杨派杨树是我国广泛分布的一类生态、经济型树种.目前尚未对青杨派杨树资源开展有效评价、利用及保护工作.以中国北方地区青杨派杨树19个种群的112个样本为材料,利用15对微卫星标记进行遗传多样性和遗传结构分析.结果表明,青杨派杨树19个种群总等位基因数(Na)为118,有效等位基因数(Ne)为3.439,观测杂合度(Ho)为0.392,期望杂合度(He)为0.347,信息指数(I)为0.582,表明青杨派杨树具有较高的遗传多样性水平;遗传分化系数(…查看全部>>
Tacamahaca is a type of ecological and timber tree species widely distributed in China.At pres-ent,little studies have been carried out on the effective resource assessment,utilization,and protection.Taking 112 samples obtained from 19 Tacamahaca populations in Northern China as research materials,this study assessed the genetic diversity and genetic structure by using 15 microsatellite markers.The re-sults showed that total number of alleles(Na)was 118,aver…查看全部>>
