Screening and Evaluation of High Temperature Resistant Grifola frondosa Strains
In order to explore mycelial growth and cultivation of Grifola frondosa liquid strains stimulated by high temperature,and to select high temperature resistant G.frondosa excellent varieties.The mycelial growth rate,full bag time,number of full bags,mycelial strength,yield of fruiting,deformity fruit body rate,non fruitng ratio,fruit bodies shape and converted efficiency of 9 different G.frondosa strains under high temperature conditions of 40℃were measured.The results showed that the No.5 G.frondosa strain was affected the least by high temperature,the full bag time was 25 days,the mycelium was strong,the av-erage yield was 211.52 g per bag,non fruiting ratio was 1.49%,the deformity fruit body rate was 4.48%,the color of fruit bodies was brown,the average size of fruit body is 14.8 cm×15.2 cm×7.6 cm,the tube hole depth was 0.79 mm,and the quality of the cap and stipe was excellent.
