| 摘 要： | 红豆树总生物量、总干物质、根、茎、苗高、地径等18个苗木性状关系矩阵及主分量分析结果表明:主分量分析中,总生物量指标的特征向量值最大,植株总生物量指标是反映苗木质量的相关中心,最能体现苗木的质量水平,植株生物量可以作为红豆树苗木质量评价的主要指标;除了生物量指标以外,特征向量值次之的为苗高和地径2个指标。植株生物量鲜重、苗高、地径3个因子最能反映红豆树苗木质量水平。

| Abstract: | The relationship matrix of 18 seedling characters of Ormosia hosiei such as total biomass,total dry substance,root,stem,seedling height and ground diameter,and main component analysis indicates that in the main component analysis the total biomass target characteristic vector value is the biggest.The total biomass target reflects the related center of seedling quality,which can manifest the seedling quality level.The individual biomass may be taken as the main assessment index for Hemsl.et Wils the seedling quality of O.hosiei.Besides the biomass index,the next characteristic vector value is seedling height and ground diameter.Best of all,the three factors of plant biomass fresh weight,seedling height and ground diameter reflect the seedling quality level of Ormosia hosiei. |
