| 摘 要： | 采用5种等位酶对长阳栓皮栎天然群体的遗传多样性和遗传变异进行了研究。共检测到7个基因位点,15个等位基因,其中5个位点为多态位点;群体多态位点比例P=71.4%,平均等位基因数A=3.2000,平均有效等位基因数AE=1.6090,平均期望杂合度HE=0.3563,观测杂合度HO=0.3625。长阳栓皮栎群体的遗传多样性较高,遗传变异水平较高。

| Abstract: | Genetic diversity and genetic variation of Quercus variabilis Blume.of natural populations of Changyang were studied at the enzyme leve1.The results showed that 7 loci and 15 alleles were detected,of which 5 loci were exhibited polymorphism.Percentage of polymorphic loci(that is P) was equal to 71.4%,the average number of alleles per locus(that is A) was equal to 3.200 0,the average number of effective alleles per locus(that is AE) was equal to 1.609 0,the expected heterozygosis(that is HE)was equal to 0.356 3,and the observed heterozygosis(that is HO)was equal to 0.362 5.The genetic diversity and genetic variation of Quercus variabilis Blume.of natural populations of Changyang were high. |
