(56(4):316-326)Effects of Culture Media and Casing Materials on Fruiting Characteristics of Coprinus comatus

評估以20%雞糞稻草堆肥與木屑營養基質（乾重比35%大麥粉，15%米糠與50%鋸木屑）二種基質栽培雞腿蘑對其產量與出菇特性之影響，發現此菇CC1菌株以木屑營養基質栽培，生物學效率與出菇產量較CC2菌株高，達顯著性差異。然而，CC2菌株以稻草堆肥栽培，其生物學效率與產量較CC1菌株高，達顯著性差異。比較泥炭土與田土二種覆土材料對出菇特性與產量之影響，結果以泥碳土覆土，對出菇所需時間較田土短且產量較高，達顯著性差異。比較四種覆土厚度對於出菇特性之影響，發現不論以稻草堆肥或木屑營養基質栽培，不覆土皆無法產生子實體，而覆土厚度以3.0cm對產量表現最佳。以塑膠袋栽與瓶栽二種方式栽培，發現袋栽生物與產菇效率，均優於瓶栽且達顯著性差異。Coprinus comatus, also known as the shaggy ink cap or shaggy mane mushroom, is the type species of the genus Coprinus, in the Agaricaceae. It is a saprophytic and edible fungus. CC1 and CC2 strains of C. comatus were cultivated separately on rice straw compost consisting of 80% rice straw and 20% chicken manure or sawdust medium consisting of 35% barley flour, 15% rice bran and 50% sawdust. When cultured on sawdust medium, the biological efficiency and mushroom yield produced by CC1 strain were higher than those produced by CC2 strain. However, when cultivated on rice straw compost, the biological efficiency and mushroom yield produced by CC2 strain were higher than those produced by CC1 strain. Our results also showed that casing with peat moss was better than casing with field soil in increasing the mushroom yield. When casing depth was 0 cm, no primordia were formed. The casing depth of 3.0 cm was better than that of 1.5 or 4.5 cm in mushroom yield, biological efficiency and production efficiency for both rice straw compost and sawdust medium. For the cultivation of C. comatus, the plastic bag which contained bigger growing area for fruiting was better than plastic bottle in mushroom yield, biological efficiency and production efficiency
