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,群体问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。
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.
