摘要/Abstract

摘要：

为了获得花斑木菌种并人工培育花斑木，从采集的花斑木中分离出菌株，将菌株接种到无花斑的西南桤木、毛白杨等木材上，以便筛选出有效菌株。共筛选菌株9种，即炭角菌属（4种）、蔡氏轮层炭角菌、扩散炭角菌、拟茎点霉、粘束孢霉、Nectria rigidiuscula，其中N. rigidiuscula在木材表面形成红色，其他菌种则由表及里产生带线花纹。Xylaria venosula、拟茎点霉和粘束孢霉是植物内生真菌或常见植物病原真菌，在8周内形成的带线花纹丰富，腐朽程度轻，是培育花斑木的优良菌种，也是首次报道的花斑木菌种。菌株在毛白杨上形成数量最多的带线花纹。

关键词: 木材装饰, 真菌鉴定, 炭角菌属, 染色, 带线花纹

Abstract:

Spalting is any form of wood coloration caused by fungal colonization. The colorful and intricate zone lines make the wood very attractive and decorative. It is valuabled to find the fungi that cause wood spalting. In this study, spalted wood was collected in the wild and the fungi in the spalted wood were isolated and cultivated, followed by inoculating the cultivated fungi on the normal wood of Alnus nepalensis, Populus tomentosa and so on. Nine fungal species were identified from collected spalted wood samples, i.e. Xylaria spp.(4 species), Nemania diffusa, Daldinia childiae, Nectria rigidiuscula, Phomopsis sp. and Graphium sp. Nectria rigidiuscula caused red stain on wood surface while others formed zone lines which extended deeply into wood. Xylaria venosula, Phomopsis sp. and Stilbum sp. are endophytic fungi and plant pathogenic fungi but had never reported as wood spalting fungi. In this study these fungi were found to bring about excellent wood spalting , which formed numerous zone lines in the inoculated wood with little wood decay in 8 weeks. Also, these fungi formed more intricate zone lines in Populus tomentosa wood than in Alnus nepalensis wood. Further research is need, especially on the mechanism of zone line formation.

Key words: wood decoration, fungi identification, Xylaria, pigment, zone lines
