本試驗目的為觀察溫度對香菇太空包內氣體組成以及菌絲生長之影響，香菇太空包於各溫度中乙烯含量普遍低於0.4ppm，二氧化碳含量隨溫度升高而上升，氧氣則隨溫度升高而降低，25°C為香茹菌絲最適生長溫度，此溫度中菌絲僅需4週即可佈滿太空包，而6°C則需16週時間，30°C下菌絲幾乎不生長。The purpose of this study was to observe the effect of temperature on the gas composition is shiitake growth bags and the mycelium growth. The ethylene concentration in each shiitake growth bag under each temperature is generally lower than 0.4 ppm. Carbon dioxide concentration slowly increased as temperature increased. Oxygen slowly decreased as temperature increased. The temperature under which the shiitake mycelium filled the growth bags completely was 25℃. This process only took four weeks, but when the temperature was under 6℃, the shiitake mycelium took sixteen weeks to fill the bags. As the temperature reach 30℃, shiitake mycelium barely grew
