在我国，杨树湿心材是一种分布广危害严重的病害。１９９５～１９９６年从湖北、山东、河北、辽宁等省及北京地区的２０多种杨树的根、干部取样，分离到一种真菌，此菌在杨树的根、干部都有广泛的分布，依据其形态特征和培养形状，据Ｎｅｌｓｏｎ，Ｔ．Ｍ．（１９８３）《ＦｕｓａｒｉｕｍＳｐｅｃｉｅｓ》，此菌被鉴定为Ｆｕｓａｒｉｕｍｐｒｏｌｉｆｅｒａｔｕｍ（Ｍａｔｓｕｓｈｉｍａ）Ｎｉｒｅｎｂｅｒｇ。室内和田间的多次接种结果表明，Ｆ．ｐｒｏｌｉｆｅｒａｔｕｍ致病力强，能产生典型的湿心材症状，是引起我国杨树湿心材的主要病原之一，这在国内外还是首次报道。电镜观察表明，此菌能破坏杨树导管—射线间纹孔膜，与国内外有关纹孔膜的报道一致。本文还讨论了细菌及生理因素在湿心材形成过程中的可能作用。
In our country, poplar wet heart wood is a widely distributed disease that is seriously endangered. From 1995 to 1996, roots and cadres from more than 20 kinds of poplars in Hubei, Shandong, Hebei, Liaoning provinces and Beijing were sampled and isolated. A fungus was isolated from this root and stem of poplar. According to its morphological characteristics and shape, according to Nelson, T. M. (1983) “Fusarium Species”, which is identified as Fusariumproliferatum (Matsushima) Nirenberg. Multiple inoculation results indoors and in the field indicate that F. Proliferative pathogenicity of proliferatum, can produce a typical symptoms of wet heartwood is one of the main pathogen causing the poplar wet heartwood, which is the first time reported at home and abroad. Electron microscopy showed that the fungus could destroy the poplar duct-ray interpenetration membrane, which was consistent with reports of parenchyma at home and abroad. This article also discusses the possible role of bacteria and physiology in the formation of wet heartwood.
