易形成菌纹线树种调查

Investigation of Wood Species Prone to Forming Zone Lines

花斑木是经真菌形成着色的木材的统称,其中,菌纹线构成错综复杂的图案,具有极高的装饰价值。研究表明材种影响菌纹线的形成,为了选择易形成菌纹线的材种以培育具菌纹线的花斑木,对西南林业大学标本库及野外易形成菌纹线树种进行调查统计。结果表明:自然条件下针叶材中易形成菌纹的树种极少,大部分阔叶材易形成菌纹线,主要归属于核桃科、槭树科、榛木科、桦木科、梧桐科、樟科等,龙脑香科、芸香科、无患子科、桃金娘科的木材较难形成菌纹线。常见的易形成菌纹线的木材包括:槭木、西南桤木、合欢、白兰、黄葛树、青钱柳、白楠、山杨等。

Spalting is the coloration on wood produced by fungi,of which,zone lines forming intricate patterns are ornamental.Researches indicate that fungal zone lines are preferentially formed in certain wood species to others.For the purpose of artificially producing spalted wood with zone lines,a survey was launched in the wood specimen of Southwest Forestry University and in the wild.Results show that zone lines rarely occurred in softwoods and often occurred in hardwoods belonging to Jualandaceae,Aceraceae,Corylaceae,Betulaceae,Sterculiaceae,Lauraceae,etc.,but was not detected in Dipterocarpaceae,Rutaceae,Sapindaceae,Myrtaceae,etc.,The wood species prone to forming zone lines inclnde Acer mono Maxim,Alnus nepalensis D.Don.,Albizzia julibrissin Durazz.,Michelia alba DC.,Ficus virens Ait.,Cyclocarya paliurus （Batal.） Iljinsk.,Phoebe neurantha （Hemsl.） Gamble,Populus davidiana Dode,etc.
