| 摘 要： | 分析樟树苗期生长性状的差异,为选择樟树优质种源提供参考依据。研究结果表明,樟树不同种源1年生苗在苗高方面整体差异不显著,地径整体差异显著。二者均无明显地理趋势变化。苗高、地径与经纬度均无相关关系。但适当分组后,苗高随经纬度总体呈现出纬度越低,苗高越大的变化规律。地径生长变化的情况受多种因素影响,比较复杂。以苗高和地径的大小表现情况,把樟树划分为6个种源区。

| Abstract: | The differences of seedling stage growth characteristics of Cinnamomum camphora were analyzed in this paper,they provide references for choosing high quality provenance of C.camphora.The research showed that annual seedling of C.camphora with different provenance haven't obvious difference in height,at the same time they have apparent distinction in diameter.Height and diameter haven't obvious geographic trends change,and also have no correlation between latitude and longitude,but after been divided appropriately,the seedling height demonstrated the change law that lower latitude while greater seedling height with the longitude and latitude.Diameter growth characteristics were rather complicated and affected by many factors.Based on the characteristics of seedling height and diameter,the provenance of C.camphora were divided into six zone. |
