Cultivation Properties of the Strain for Sugi (Cryptomeria japonica) Wood in Sawdust-Based Cultivation of Lentinula edodes

Abstract

Breeding and screening of strains suitable for sugi wood culture were performed to establish the cultivation technique for sawdust-based cultivation using sugi wood for Lentinula edodes. As a result, HS807 was selected as a strain suitable for sugi (Cryptomeria japonica) wood sawdust-based cultivation. HS807 gave about 6 times higher yield than that Hokken No. 600 which is suitable for hardwood sawdust-based cultivation. However, the yield was about one half compared with that of hardwood sawdust-based cultivation. Physical and chemical analyses of mycelial blocks were performed to evaluate incubation properties of the HS807 strain suitable for sugi wood. As a result, mycelium in sugi wood medium is found to be of lower quantity as compared to konara wood medium. Therefore, it was suggested that the increase in the quantity of mycelium during incubation is an important factor for evaluation of fruit body flushing.
