Abstract

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 $13^{\circ}C$, $17^{\circ}C$, and $15^{\circ}C$. 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 $17^{\circ}C$ respectively. In variable temperature with a variable temperature plot, condition II($17^{\circ}C$ for pin-heading(before reverting, 7-8 days)${\rightarrow}16^{\circ}C$ for extending primodia(before thinning, 4-5 days)${\rightarrow}15^{\circ}C$ 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.

온도가 수확율과 수확기간에 미치는 영향은 방임과 솎음 공히 온도가 낮을수록 발이소요일이 길었고, 수학소요일도 같은 경향을 보였다. 수확률에 있어서 $13^{\circ}C$에서는 91%, $17^{\circ}C$에서는 90.3%, $15^{\circ}C$에서는 95.8%로 가장 좋은 결과를 보였다. 온도가 낮은 것은 발이가 불량하여 수확률이 떨어진 것이고, $17^{\circ}C$ 조건에서는 갈반병이 발생하여 수확률이 떨어졌다. 솎음처리구에서 품질은 생육온도가 13, 15, $17^{\circ}C$일때 각각 7.5, 8.1, 7.7로 $15^{\circ}C$ 처리가 가장 우수하였고, 수확량에 있어서는 $17^{\circ}C$ 처리에서 100.0g으로 가장 많았다. 방임처리구에서의 온도의 영향은 솎음처리구와 마찬가지 경향으로 13, 15, $17^{\circ}C$일때 품질은 각각 4.6, 5.9, 5.1로 $15^{\circ}C$가 가장 우수하였다. 무게에 있어서는 $15^{\circ}C$처리에서 107.2g으로 가장 수량이 많았다. 생육시기별 온도를 달리 적용하였을 경우, II조건($17^{\circ}C$ 발이기(뒤집기전, 7~8일)${\rightarrow}16^{\circ}C$ 원기신장기(솎기전, 4~5일)${\rightarrow}15^{\circ}C$ 신장기(솎기이후))가 생육소요일수가 16일로 가장 짧았으며, 수확량도 방임의 경우 다른 처리에 비해 22.4, 9.0% 증수되었다. 솎기구의 경우 품질이 8.1로 다른 처리구 7.1과 7.9보다 우수하였다. 총생산량에 있어서는 17.4, 4.0% 많았다.
