摘要
文中分析白蜡早春萌芽期含水量与枝条颜色变化的关系,用以从外观上判断早春萌芽情况。试验结果表明,枝条含水量随萌发进程而变化,在芽萌发前期枝条的含水量急剧下降,之后随芽的萌发含水量增加,枝条颜色随含水量与芽萌发进程呈现出明显的变化。
The relation between water content and branch color of Fraxinus chinensis Roxb. at its germination period in early spring was analyzed, and the germination at early spring was estimated from its appearance. The result indica- ted that the water content in branches changes with the germination process, i. e. , dramatically declining at the early stage of germination, and then the water content went up with the germination process. Branch color showed tangible variation as the water content and germination process changed.
