摘要
以黄梁木Neolamarckia cadamba 11个种源为材料,在广东雷州、海南东方和海南海口3个试验点开展种源试验,调查2年生幼林的胸径、树高、材积等生长性状。结果表明,在3个试验点,所有性状在地点间、种源间、地点内区组间、种源与地点内区组交互项以及地点与种源交互项的差异均达极显著水平。根据稳定性分析可将参试的11个种源划分为3大类。
Eleven provenances of Neolamarckia cadamba were used as materials to carry out provenances test in three experimental sites, Leizhou in Guangdong, Haikou and Dongfang in Hainan The diameter at the breast height （DBH）, tree height and volume of 2-year-old young plants were investigated, and the statistical analysis was carried out. Results showed that all growth characteristics among sites, provenances, the blocks within the sites, the interaction of site and provenance, the interaction of provenances and the block within the sites were all significantly different. Eleven provenances could be divided into three groups.
