| 摘 要： | 为探讨人工砍伐后短柄枹栎(Quercus glandulifera var.brevipetiolata Nakai)居群的遗传关系,采用SSR分子标记技术,对短柄枹栎天然林中的4个次生林居群的遗传多样性、遗传结构进行研究。结果表明,筛选的7对SSR引物在4个居群内共揭示了101个等位基因。砍伐后恢复20年(20YAH)的短柄枹栎居群的遗传多样性最高,而砍伐后恢复1年(1YAH)和10年(10YAH)的遗传多样性相对较低。从长远来看,试验地居民特殊的砍伐习惯不会造成短柄枹栎天然林遗传多样性的变化。

| Abstract: | In order to understand the genetic relationship of Quercus glandulifera var. brevipetiolata Nakai population, the genetic diversity and genetic structure in four secondary populations of Q. glandulifera var. brevipetiolata community were studied by using SSR markers. The results showed that 101 alleles existed in the four populations of Q. glandulifera var. brevipetiolata by using 7 pairs of SSR primers. The genetic diversity in population of 20-year after havesting (20YAH) was the highest, while those of 1YAH and 10YAH were low relatively. In the long term, the special logging habits of local residents will not influence the genetic diversity of Q. glandulifera var. brevipetiolata nature forest. |
