为研究芒草在其重叠分布区内表型性状的遗传多样性,以来自于华东植物区系内的36份芒、五节芒、荻和南荻为材料,对8种表型性状进行多因素方差分析、变异分析和聚类分析.结果表明:8种表型性状种间差异大小依次为分蘖数、基部直径、干物质产量、花序长、株高、最大叶长、最大叶宽、叶长宽比,在种内除最大叶宽与叶长宽比呈显著差异(P

In this study, 36 samples of Miscanthus spp. including four species (M.sinensis, M.floridulus, M.sacchariflorus, M.lutarioriparius) from East China region were used to study the genetic diversity of the phenotypic characters of Miscanthus spp. during their overlapping region. Their 8 phenotypes were subject to multivariate variance analysis, correlation analysis, clustering analysis. The results showed the interspecific difference trend in the studied phenotypes of Miscanthus spp. decreases as the following order, tiller number, basal diameter,...
