摘要:

测量了福建小叶买麻藤11个种群116个植株1 139片叶的15个性状。分析得出小叶买麻藤物种多样性指数为19281,种群内平均为17573。小叶买麻藤的遗传变异主要集中在种群内部(9114%)。UPGMA聚类和Mantel检验支持遗传距离与地理距离成显著正相关关系(r=06216,P=00020<0005)。种群分化呈现距离隔离格局。

Abstract:

 Fifteen characters were measured in 11 populations of Gnetum parvifolium in Fujian Province, including 1139 leaves from 116 plants. The diversity index is 19281 at species level and 17573 at population level. 9114% of all genetic variation is distributed within populations. UPGMA cluster analysis and Mantel test also support that there is a positive correlation (r=06216, P=00020<0005) between genetic distance and geographic distance. The population differentiation conforms to the isolationbydistance pattern.

Key words: Gnetum parvifolium, Population, Genetic variation, Morphology of leave
