| 摘 要： | 天然群体包含大量数量和质量性状变异,前者易受环境条件影响,后者则几乎完全受遗传因素控制。长期以来,人们主要利用表型性状借助数量遗传理论来研究群体的遗传变异,直到近十多年才开始借生物化学技术作林木遗传学分析。本研究以福建省15个马尾松垂直和水平分布的天然群体为对象,利用同工酶位点探讨马尾松群体的遗传结构,了解马尾松垂直和水平群体在各种酶类多态位点上的变异幅度和趋势

| Abstract: | Genetic structures between and within 15 masson pine populat ions were studied by vertical and horizontal isozyme distributions in Fujian Province. The results indicated that there were great deviations among them with heterogeneity of allelic frequency being 0.357. Through genetic distance and gene division index analysis, it was discovered that there were more divergences among horizontal populations than among vertical ones. This paper also discussed the heterogeneity gradient along latitude and genetic deviation's maintenance. |
