|
The effects of cultural conditions on the mycelial growth and fruit-body formation and the yield of Pleurotus sajor caju grown in rice straw medium were examined. The change of content of chemical components of mushroom and the medium during the cultivation period was also examined. The growth of mycelium was best in the medium sterilized for 60 min at 1.2㎏/㎠ with a moisture content of 60%. The optimum pH and temperature for mycelial growth were 6.0 and 25℃, respectively, whereas the optimum pH and temperature for fruit-body formation ranged from 5.0 to 6.0 and from 20 to 30℃, respectively. Rice bran and starch cake were better than the other additives used for both mycelial growth and fruit-body formation. The optimum concentration of rice bran in the medium was 10%. The total yield of mushroom was 20.2㎏/㎡, 66% of which was produced from the first and second cropping period. As the harvest proceeded, the crude fiber cotent increased in the mushroom, whereas it decreased in the medium. The content of free sugar and crude ash, un the other hand, decreased in the mushroom, whereas it increased in the medium. The content of the other chemical components examined decreased in both the mushroom and the medium
