Abstract
Effects of moisture and rice bran contents on fruit-body production on sawdustand beet pulp-based substrates in Pleurotus cornucopiae var. citrinopileatus were investigated. In case of the sawdust-based media being low nitrogen contents, the days required for fruiting initiation and the yield of fruit-bodies were largely influenced by the rice bran contents in the media, but not so much by the moisture contents. On the other hands, the beet pulp-based media, which showed high nitrogen contents, produced higher yields of fruit bodies than those in the sawdust media, but the days required for fruiting initiation were rather influenced by the moisture contents. These results suggested that the differences in the substrates may be more influenced than the differences in moisture contents in the cultivation of this mushroom. The possibility for controlling fruit-body production by adjusting the optimal moisture and rice bran contents in the substrates was also suggested.
