摘要
本文研究了松木边材的蓝变。结果表明：无论是康宁木霉（ＴｒｉｃｈｏｄｅｒｍａｋｏｎｉｎｇｉＯｕｄ）或长喙壳变色菌（Ｃｅｒａｔｏｃｙｓｔｉｓｓｐ．），均是晚材先于早材变色，且变色程度较早材严重。自由基相对含量与变色程度之间存在相关性，松木边材变色与树脂道、木射线、内含物及木材含水量等因子密切相关。
The paper deals with sap blue stains of pine woods. The result shows that the colour change of latewood caused by both Trichoderma koningii and Ceratocystis sp. are earlier and greater than earlywood. We concluded that the corelationship between free radical contents and stain degrees is evident by the study of ESR. The sap stain of pine woods are closely related to such elements as resin canal, wood ray, extractives, water content etc.
