摘 要:红椿(Toona ciliata)与思茅红椿(Toona ciliata var.henryi)同属于香椿属植物,思茅红椿为红椿的一种变种。红椿为国家II级保护植物,而思茅红椿为非保护树种,在识别与鉴定两种木材上具有重要意义,同时为植物学分类提供一定依据。两者具亲缘关系,在木材解剖构造上具一定相似性和差异性,通过两者差异性可区分两种木材,由此可对两种树种作出区别。在宏观上两者差异体现在材色、年轮宽度、薄壁组织类型不一;微观构造上,两者的轴向薄壁组织类型、晶簇及晶体个数及木射线高度有明显差异。Toona ciliata and Toona ciliata var. henryi belonged to toona. Toona ciliata was second-grade protection wild plant in China, and Toona ciliata var. henryi wasn’ t protection plant. It was of great significance in the identification and evaluation on two kinds of lumber, at the same time, the identification and evaluation provided certain basis for botanical classification. They had genetic relationship in wood anatomical structure on certain similarities and differences. Through the differences people can distinguish the two kinds of wood and tell the difference between the two trees. The differences existed in wood color, the width of annual ring and the type of parenchyma from macroscopic structure. The differences existed in the type of parenchyma,the number of crystal and the height of wood ray from microscopic structure.
