通过对少穗竹的胸径、竹高、枝下高、节间长等秆形因子进行了调查分析,结果表明:立竹胸径与竹高具有显著相关性,最佳拟合方程为H=0.1373D+2.1639(R=0.976),H=0.4401D0.7726(R=0.979);立竹胸径与枝下高相关性系数不高;尖削度最佳拟合方程为Y=0.0011X3-0.0246X2+0.0399X+1.0266(R=0.997);节间长随高度的增加先增大,后减小,最大节间长出现在第9～11节处,节长与节间的最佳拟合方程为Y=0.006X3-0.3997X2+6.7965X+9.1536(R=0.984)。
The results showed that the diameter of standing bamboo had a significant correlation with bamboo height, and the best fitting equation was H = 0.1373 D = 2.1639 (R = 0.976), H = 0.4401D0.7726 (R = 0.979). The coefficient of correlation between DBH and branch height was not high. The best fit equation of tip taper was Y = 0.0011X3-0.0246X2 + 0.0399X + 1.0266 (R = 0.997). The length of internode increased first and then decreased with the increase of height, and the maximum internode length appeared at 9th to 11th. The optimal fitting equation Y = 0.006X3-0.3997X2 + 6.7965X + 9.1536 (R = 0.984).
