生漆是优良的天然涂料,它是漆谢(Rhus vernicifua Stokes)代谢过程中的次生产物,由漆树体内的漆汁道分泌和贮存的。关于漆汁道在树皮内的结构、分布、长度和分枝等方面的规律,西北大学胡正海副教授等人已作了全面系统的研究。但是有关漆树树皮内漆汁道堵塞现象的观察研究,至今未见报道。现将我们的观察研究结果报道如后。 Raw lacquer is an excellent natural coating that is a secondary product of Rhus vernicifua Stokes metabolism that is secreted and stored by paint lacquers in lacquer trees. With regard to the law of the structure, distribution, length and branching of the paint juice in the bark, an associate professor of Northwest University, Hu Zhenghai and others have made a comprehensive and systematic study. However, there is no report on the observation of clogged lacunar in tree bark. Now report the results of our observation.
