Abstract

Changes of fruiting body yield and morphology according to growing temperatures in Pleurotus strains were investigated. In this study, twelve commercial strains divided into low, medium and high temperature groups were tested. On the basis of fruiting body yield, they showed best in their own temperature properties. On the other hand, they didn't have any fixed tendency to growing temperatures on morphological characteristics. Thicknesses of pilei were best at $10^{\circ}C$, having nothing to do with strains. Lengths of stipes were increased with the progress of cultivation temperatures in five strains including 'Sambok'. The other strains showed differences on this trait. Thicknesses of stipes were decreased with the progress of cultivation temperatures in other strains excepting 'Sambok and ASI2029'. Days for harvest were extended as temperature decreased, even though the shortest days were different according to strains. Sometimes there were abnormal shapes of fruiting bodies in response to temperatures in some strains. In 'Suhan-1', white cilia fully covered onto the surface of pilei were observed macroscopically at the early stage and then disappeared or remained a little later at $10^{\circ}C$ cultivation. In 'Chunchu-2', their stipes were twisted and bent over $20^{\circ}C$ cultivation.
