The effects of fixed and variable temperatures on fruiting body formation and characters of mushrooms were investigated with normal and thinning treatment plots. In fixed temperature, as temperature was lower, period of harvest was longer as well as days for pinheading in the both of normal and thinning plots. Harvest rate were 91.0, 90.3, and 95.8% at 13℃, 17℃, and 15℃. In the thinning plot, qualities of mushrooms were 7.5, 8.1, and 7.7, and yields were 86.0, 105.9, 104.0g at 13, 15, and 17℃ respectively.
In variable temperature with a variable temperature plot, condition Ⅱ(17℃ for pin-heading(before reverting, 7-8 days)→ 16℃ for extending primodia(before thinning, 4-5 days)→15℃ for extending (after thinning)) was the best for yield which was better than other conditions by 17.4% and 4.0% and quality of mushroom was highest 8.1 among all conditions.
