摘要

四種木耳菌株以0，5，10，20，28，35，40及45℃溫度處理24，28及72小時，發現在不同溫度處理期中，20℃以下或35℃以上溫度對木耳菌絲之活力有嚴重影響，處理後移至28℃培養時，經一般溫度處理之菌絲活力要在36小時後才能漸漸恢復，但40℃以上高溫處理者，仍無法恢復其正常活力。各種不同溫度處理對木耳菌絲活力之影響與處理時間有很大關係，處理24小時者活力恢復較處理45小時或72小時者爲快，處理48小時者又比72小時爲快，此種差異至爲明顯，甚至在28℃環境下培養72小時，仍然無法消除處理時間對菌絲活力的顯著影響。

並列摘要

Four isolates of Auricularia polytricha were treated with 0, 5, 10, 20, 28, 35, 40 or 45℃ for 24, 48 or 72 hours to study the effect of temperature on the growth vigor of the mycelium. It was found that the growth vigor of the mycelium was significantly affected when it was treated with the temperature of either below 20℃ or higher than 35℃. More than 36 hours of incubation at 28℃ was needed for recovering the vigor of mycelium, but it was hardly recovered when ft was treated with 45℃ or higher temperature. The reduction of growth vigor was in proportion to the duration of temperature treatment. The longer treatment of unfavorable temperature needed the longer tune for the recovery of mycelial vigor
