茶树菇农艺性状比较及菌株筛选分析

Primary research on agronomy traits of Agrocybe aegerita

对17种茶树菇菌株的菌丝长势、菇体颜色、抗逆性、开伞度、产量及生物学效率等多项农艺性状进行评比实验。结果显示,茶树菇大部分菌株菌丝长势都很好,较易开伞,具有较强抗逆性,原基发生约34 d^48 d,初潮时间约40 d^53 d,且生物学效率近50%以上,其中浅灰褐色品系菌丝长势偏好。但白菇和As-F各项农艺性状均较弱。综合比较后筛选出优良的核心菌株As-1。

In this paper, 17 Agrocybe aegerita strains＇s many agronomy traits which are mycelium growing, color of sporophore, stress resistance, difficulty of pileus-open, yield, biological efficiency and so on, are used in comparison ex periment. The results showed that most of strains have very good mycelium growing, easy pileus-open, strong stress resis tance. Their primordium appearance used about 34-48 days; first fruiting spent 40-53 days; biological efficiency nearly 50% above. Terra brown Strain has better growth vigor. But White-mushroom and As-F＇s agronomy traits are weakly. Af ter comprehensive comparison, we selected As-1 which is the fine core of the relative strain.
