| 摘 要： | 该试验通过对香樟单株叶片、枝条含水量和电导率的分析,比较了不同香樟单株抗寒性的差异.试验结果表明,香樟单株不同,其叶片、枝条含水量有显著差异,且1a生枝条含水量＞叶片＞2a生枝条;随着冬季来临,香樟枝、叶含水量下降的程度因单株不同而有差异;香樟枝、叶的相对电导率随温度的下降显示不同的规律.Al相时电导率最小,抗寒性最强.

| Abstract: | The water content and relative conductivity in leaves and branches of Cinnamomum camphor individuals were measured to study its cold resistance in this paper.The results showed that the water content of leaves and branches was significantly different between the individual trees,and water content in one-year-old branches was > in leaves> in two-year-old branches in the same individual.As winter came,the decrease of water content in leaves and branches varied among the individual trees.The decrease of relati... |
