【中文摘要】 本文比較了雙核菌絲制備的香菇原生質(zhì)體在不同培養(yǎng)基上的再生率,觀察了原生質(zhì)體再生過(guò)程.以存活率37%的劑量進(jìn)行紫外線誘變處理后,選出102份再生克隆,從中選出在CM培養(yǎng)基和木屑培養(yǎng)基上菌絲長(zhǎng)速較快的材料23份,進(jìn)行栽培試驗(yàn),其中10份產(chǎn)量提高,出菇較早.在隨后的二次或三次組織分離后代的栽培試驗(yàn)中,大部分材料保持了增產(chǎn)、早熟的性狀,經(jīng)顯著性測(cè)驗(yàn).其中2份材料的產(chǎn)量顯著提高.本研究初步建立了用原生質(zhì)體誘變技術(shù)選育香菇菌株的試驗(yàn)程序.

【英文摘要】 The regeneration efficiency of Lentinula edodes protoplast prepared from dikaryon mycelium was compared on different media and the regeneration procedure was also observed under inverted microscope. 23 clones with more rapid mycelium growth rate on CM medium and sawdust medium were selected from 102 regenerated clones after being treated by UV radiation at D37 dosage. The cultivation experiment showed that 10 of the 23 regenerated clones expressed the characters of yield increment and early fruitbody formation, and that most of the progeny obtained through 2 or 3 times of tissure separation kept the characters of yield increment and early maturity and the yield of 2 regenerated clones increased significantly according to the significance test. In addition, the experiment procedure for selecting L, edodes strains with protoplast technique was also established in this study.
