调查研究江西省17个天然毛竹林种群(Ⅲ度竹)的胸径、全株杆鲜重、全株枝叶鲜重、杆长、全杆节数、枝下节数、枝盘数、枝下高、叶长和叶宽、叶片长宽比、胸径处竹壁厚度、竹腔径、壁腔比、竹材含水率等表型特征。运用SPSS 13.0软件进行多元线性回归分析和偏相关分析,结果表明:全株秆鲜重、秆长、枝下节数、枝下高、胸径处壁厚、竹腔径呈现随经度而变化的地理模式,与纬度、海拔无关;胸径受经度和纬度的双重影响;枝盘数呈现随海拔而变化的地理模式。
The results showed that the diameter at breast height, the fresh weight of whole plant, the fresh weight of whole plant, the length of stem, the number of full stem, the number of branches, the number of shoots and the height of branch were investigated in 17 natural bamboo forests of Jiangxi Province , Leaf length and leaf width, leaf aspect ratio, bamboo thickness at the diameter of the breast, bamboo cavity diameter, wall cavity ratio, bamboo moisture content and other phenotypic characteristics. Multivariate linear regression analysis and partial correlation analysis using SPSS 13.0 software showed that: the whole plant stalk fresh weight, stalk length, branch number, branch height, wall thickness at breast diameter, bamboo diameter showed a change with longitude Mode, independent of latitude and altitude. The DBH is affected by both latitude and longitude. The number of branches shows the geographical pattern changing with altitude.
