Abstract
In order to test the fruiting body production of Panellus serotinus, we prepared various sawdust-rice bran media in which the size of sawdust particle of Fagus crenata (0.25-1.0mm and 1.0-2.0mm in diameter), sawdust-to-rice bran ratio (10:1 to 10:3), and moisture contents (55-70%) were varied. It was determined that optimal temperature for fruiting of P. serotinus was at 10℃ when the spawn running was performed for 90 days at 23℃. High moisture content and high rice bran content of the media tended to increase the number of watery fruiting bodies. It appeared that the medium composed with small sawdust particle, 10:3 of sawdust-to-rice bran ratio, and 65% of moisture content was suitable for the cultivation of this mushroom. The CO_2 content and the air ratio against the medium volume in the plastic bag at 90 days of the mycelium incubation (the timing of fruiting treatment) was 3.1-3.3% and 34-46%, respectively.
