【摘要】 采用組織分離法,對采自云南中甸、麗江、武定、巍山4個地方的松茸進行了分離培養(yǎng),并利用感官及ITS測序?qū)λ囵B(yǎng)的菌絲進行了鑒定。結(jié)果表明,利用斜面培養(yǎng)基很好地誘導(dǎo)出了菌絲體母種,誘導(dǎo)率達75%;而將分離培養(yǎng)得到的菌絲體進行液體培養(yǎng),菌絲生長良好,且能進行轉(zhuǎn)擴和較大規(guī)模培養(yǎng);液體培養(yǎng)的菌絲體仍具有松茸的特殊氣味,證明可能為松茸的純培養(yǎng)物;經(jīng)ITS測序比較,采自中甸、麗江、武定、巍山的松茸子實體和其液體培養(yǎng)的菌絲體,其遺傳相似度分別為0.9970、1、0.9980、0.9980,表明取自不同地點的子實體與其相應(yīng)的培養(yǎng)物在種質(zhì)上是一致的。

【Abstract】 In this study,the mycelia of Tricholoma matsutake from Zhongdian,Lijiang,Wuding and Weishan were cultivated by the method of tissue separation and identified by the method of sense organ distinguishing and ITS sequencing.The results showed that the mycelia of maternal strain were well induced and the rate of induction is 75% on the slant medium of PDA+ yeast extract paste(0.5%).The mycelia gained above could grow very well and be cultivated in larger scale on liquid culture medium.The mycelia of liquid culture had special smell as which Tricholoma matsutake had,and this showed it were likely to be pure culture from Tricholoma matsutake.By ITS sequencing,the genetic identities,between mycelia of liquid culture and fruiting body from Zhongdian,Lijiang,Wuding and Weishan,were 0.997,1.00,0.998 and 0.998 respectively,that implied the mycelia were indeed from their corresponding fruiting body.
