| 摘 要： | 对红锥博白、浦北、东兰3个种源苗高和地径生长率2年生苗木生长节律进行了研究。结果表明:3个种源Logistic方程拟合效果都显著,均呈"S"型生长模式。采用有序样本聚类分析方法将苗木的生长过程划分为4个时期:生长初期、速生前期、速生期、生长后期。方差分析及多重比较结果表明,3个种源苗木生长量存在显著差异,博白种源和浦北种源较好,东兰种源次之。

| Abstract: | The growth rhythm of two year old Castanopsis hystrix seedlings among provenince(Bobai,Pubei and Donglan) was investigated.The results showed that the growth rhythms of seedlings from the three provenince were consistent with the logistic equation,reflecting a ’S pattern’ in both height and basal diameter growth.A sequential clustering analysis was used to partition the seedling growth into four periods: early growth period,a period before fast-growth,fast growth period and later growth period.Analysis of variance and multiple comparison showed that the C.hystrix of different origins varied in their seedling growth,with seedlings from Bobai and Pubei growing faster than that from Donglan. |
