基　　金：重庆市科技攻关项目"彭水县野生牛肝菌人工驯化关键技术研究"(CSTC;2010AC1111);"武陵山区食用菌良种高效栽培试验示范"(CSTC;2010AB1047);重庆市林科院科技计划项目"万州区老林村林下食用菌栽培示范";"重庆桉树;竹林林下种植模式技术研究"

摘　　要：通过2种不同的培养基对彭水2种野生牛肝菌子实体进行分离、培养,同时,进行液体培养,培养的菌丝经过ITS鉴定,放入-80℃超低温冰箱中保藏。结果表明,2种牛肝菌菌丝均从组织块表面边缘生长,菌丝洁白、小,不向周围培养基生长,老化速度较快,老化过程中菌丝减少,最后变为固体状物,并且分泌褐色水珠;液体培养菌丝体生长缓慢,培养时间较长,菌丝球小、少;菌丝球经过鉴定后,确定2种牛肝菌均为美味牛肝菌。Through two different culture medium, two wild Boletus edulis were seperated and cultured, and training hyphae were identificated by ITS, which were stord in the refrigerator of -80℃. The results showed that the two Boletus edulis hyphe liver tissue were growth from mass surface edge, and the hyphe were white and small. The hyphe didn＇t grow around the culture medium, and aging faster. The mycelia by liquid culture grew slowly, and the ball was small. Hyphae ball by determining were Boletus edulis.
