Bottle cultivation was conducted to clarify varietal differences and physiological characteristics of oyster mushroom under different temperatures. Mushroom pinheading and yield in each temperature showed different results according to the strains. Specially, Weonhyeong3-ho could not sprout over 16.5℃ , but after pinheading at 13℃, its fruitbody was able to grow normally at all tested temperatures. Sambok, a high temperature strain, sprouted at 10℃ and then withered up. Fruitbody of this strain obtained at 13℃ could not grow normally at 10℃ and 25℃ conditions. Colour of fruitbodies turned close to white at high temperature. On the other hand, at low temperature, strains with gray fruitbody changed close to black and those with brown fruitbody turned to dark brown. With regards to fruiting trait, pinheading aspects were good even at low temperature. Those were, however, uneven and sprouted in patches and resulted in low quality and productivity as the temperature increased. When black fruitbody at 13℃ were moved to 23℃ and then to 13℃ again, colour of fruitbody turned to white and then recovered to blackish gray. These results confirmed that the colour of fruitbody responds to cultivation temperature.
