摘　　要：One strain of Hypoxylon sp.CXM-3 and one strain of Sistotrema brinkmannii CXM-4 were inoculated onto sterilized cherry,poplar,birch,and basswood sheets in a certain shape and incubated at constant temperature and humidity for 4,8,12,and 16 weeks,respectively,to analyze whether the grain pattern formed by the zone lines was consistent with the predetermined pattern.The results showed that the zone lines of CXM-3 of Hypoxylon were free,delicate,and soft,with brown lines and black staining,mostly accompanied by black and brown dots,facets,and clusters,while the zone lines of CXM-4 of Sistotrema brinkmannii grew along the predetermined grain,with strong lines and a clean surface.After inoculation and incubation at a constant temperature of 25℃±2℃ and humidity of 60%,Sistotrema brinkmannii CXM-4,on basswood veneer at 4-8 weeks and cherry veneer at 4-16 weeks,were able to develop zone lines following a predetermined grain.Artificially induced spalted wood can only maintain a large shape,which cannot guarantee that the pattern of large-scale production of spalted wood is exactly the same and cannot be accurate to the minute details.The artificial induction can thus result in the formation of a predetermined grain pattern of the mottled wood,thus enhancing the product value and artistic value of solid wood furniture and crafts.
