| 摘 要： | 对6个苦楝群体进行苗高生长测定,其方差分析结果表明,在所观测的9个生长期中,除了生长初期的5月25日和6月26日之外,群体让F值都达到极显著差异（0．01）,群体内都：达到极显著差异（0．01）。苦楝苗高生长呈典型“S”生长曲线,其苗高生长曲线方程为：H=192．8／（1＋391．7e^-0.0894x）。在不同观测周期中,群体间、群体内家系间生长节律经t检验具不同程度的差异显著性。

| Abstract: | Determination was made on seedling height growth of 6 Melia azedarach populations. The variance analysis indicated that the F values had significant difference(0.01) among populations except the first two in 9 growth periods, but significant difference(0.01) within populations in 9 growth periods. The growth rhythm of height was like "S" curve, the equation was H=192.8/( 1 + 391.7e-0.0894x). It was significant in a way among /within populations with "t" test in different observation periods. |
