<正>对南京椴木(Tilia miqueliana Maxim)的边材变色菌进行了分离培养、鉴定和变色试验。分离培养结果表明,变色边材经分离,37％组织上长出了Lasiodiplodia,22％的组织上长出了Macrophoma,长出细菌、其它真菌和没有长任何真菌的组织占41％。变色试验证明,这两种真菌都能引起杨木的变色。根据这两种真菌的形态特征鉴定为Lasiodiplodia [Botryodiplodia]theobromae (pat.) Griff & Maubl.和Macrophoma nicotinae Sousa da Gamara。这两种真菌出现在南京椴的变色边材部分,属首次报道。

This paper gave the sapwood stain fungi on the Tilia miqueliana Maxim, an isolation, culture, identification and staining test. The result showed that Lasiodiplodia and Macrophama came out of the 37% and 22% from the tissue of stain sapwood isolated respectively, tissue of bacteria, other fungi and no any fungi were 41%. Staining test showed that poplar wood stain was caused by the both of fungi. On the basis of morphological characters, the both fungi were identified as Lasiodipladia (Botryodiplodia) theobrumae (Pat. ) Griff Maubl. and Macrophoma nicotinae Sousa da Gamara. The both of was first reported on the Tilia miqueliana Maxim, staining sapwood.
