不同成熟度採收洋菇對產量之影響

A Study on the Influence of Maturity at Picking on the Yield of the Cultivated Mushroom

洋菇菇體按菌傘直徑達2 cm，4 cm，6 cm，及8 cm。四種不同成熟度來採收，在發現第一個直徑達1 cm之菇蕾時開始栽培五十天，所產之洋菇以未切除多餘菌柄之菇體重量計算，其產量差異極為顯著，有成熟度愈大產量愈高之趨勢，但以菇體切除多餘菌柄部份後而且不開膜合乎商品規格之菇體來說，則以4 cm處理區之商品菇產量最高，8 cm處理區最低。各處理區生產新菇蕾數目以2 cm處理區最多，8 cm處理區最小，成熟度愈大出菇蕾數目愈少。同時成熟度愈大採收洋菇之個數愈少，而洋菇個體重量愈大，且產菇之週期日數愈長，週期次數愈少。在菇體本身來說，成熟度愈大，菌傘之直徑，厚度與重量及菌柄之長度，直徑與重量均隨之增加。

The stage of maturity of cultivated mushrooms were defined to 2 cm; 4 cm and 8 cm diameter of pileus of the sporophores. The stage of maturity at which sporophores were picked affected the cropping. The yield of untrimmed sporophores increased with the later stage of maturity but the yield of marketable mushrooms-trimmed and close-veil sporophores decreased. The average weight per sporophors and the weight; length; diameter; thickness of pileus and stipe increased with the stage of maturity, but the number of sporophorse was reduced .It also increased the days of each flush number of flushes.
