Effects on yield of Pleurotus ostreatus(Suhanneutari 1ho) according to afterripening conditions with bottle cultivation

This study of afterripening conditions during oyster mushroom (Suhanneutari 1ho) cultivation in bottles was investigated. Medium materials were used poplar-sawdust (68%), cotton seed peel (16%), Beet pulp (8%) and cotton seed cake (8%). Mix of materials was used as a percentage of the volume and to adjust moisture content (67%). Autoclaved mediums were placed in low temperature storage (20℃) and then moved in inoculation room and conducted mechanical inoculation. Mycelial culture temperature was maintained at 20~21℃ and cultured during 18 days. The afterripening period were 6days, 9days, 12days and 15 days at 25~27℃. The yield of fruit body was higher for 9 days (163.1g/bottle) and 12 days (160.7g/bottle) than that of other afterripening period. Second, in the changes in moisture content of the medium according to the afterripening period, no significant changes were observed during mycelial grwoth. The longer afterripening period was showed slightly lower weight of media. The moisture content of media after harvest at afterripening for 9 days had the biggest reduction than any other treatments. In addition, weight of media and yield of afterripening for 9 days were the lowest and highest, respectively.
