摘　　要：分别测量与分析了红豆树立木的胸径、树高、枝下高、胸高心材比率、枝粗系数、树干通直度系数、枝下高系数等13个性状特征及其变异程度,及各主要性状间相关关系进行了探讨。结果表明,材积生长与胸径、冠长、Ⅰ级侧枝粗度、树高、枝角、通直度呈极显著正相关,与枝下高呈显著相关。红豆树材用性优树选择因子的重要性序列为:胸径、枝下高、树高和胸高心材比率;枝下高与通直度可择其一作优树选择的评价指标;枝粗系数可作为红豆树干材的形质控制指标。The 13 characters of Ormosia hosiei Hemsl. et Wils. individuals including diameter at breast height （DBH）, height, under branch height （ UBH）, heartwood rate at breast height （ HRBH）, course branch coefficient （ CBC ）, stem straightness coefficient （SSC） and under branch height coefficient and their variation were measured and analyzed, and the correlation between the characters was also discussed in this paper. The results showed that the volume of O. hosiei Hemsl. et Wils. individuals was significantly positive relation with DBH, height, SSC, UBH, canopy length, diameter of lateral branch of grade I and branch corner. As the factors for choosing superior individuals of O. hosiei Hernsl. et Wils. , the importance of the characters was in the order： DBH 〉 UBH （or SSC） 〉 tree height 〉 HRBH. CBC could be used as an index for the stem profile of O. hosiei Hemsl. et Wils.
