Abstract

|
Some factors effecting on the mycelial growth and primordia formation of Agrocybe cylindracea were investigated. Among supplements added into sawdust, wheat bran was the best for the mycelial growth, and its appropriate concentration was 30070. A variety of sawdust preparations was, tested singly and in combinations. Oak sawdust and the combination of oak and larch sawdust were the most effective for the mycelial growth. The optimal moisture content was 65070, and the range of optimal temperature was 25∼28℃. The favorable conditions for the primordia formation appeared to be similar to those of the mycelial growth. Among supplements added into sawdust, wheat bran 30% and the combination of wheat bran and rice bran 30% were the best for the primordia formation. Oak sawdust, and the oak plus larch sawdust and oak plus poplar sawdust were the best for the primordia formation. The optimal temperature for the primordia formation was 17±2℃.
