臺灣栽培種洋菇（Agaricus bisporus）子實體的發育

The Development of Fruiting Body of Agaricus bisporus (Lange) Singer Cultivated in Taiwan

臺灣栽培種洋菇（#543）子實體之生長曲線類似S型，菌柄之增長及菌傘之橫張在菌傘即將破裂至完全張開之期間最快。無論菌柄或菌傘，其生長均非全面性，菌柄之生長以菌環以上部份最快菌傘則以邊緣為最，中間部份生長甚慢或幾乎不長。菌柄生長帶（Growing zone）上細胞之延長及增大與子實體之高度及菌柄之加粗成正相關。

The growth of the fruiting body of Agaricus bisporus #543 showed a typical sigmoid curve. The height of the carpophore and diameter of the pileus reached their maximum velocity between the stage when the pileus began to open and until it became flat. The detailed study of the growth region showed that only a narrow zone at the top of the stipe, between its attachment to the pileus and ring was where vigorous growth was taking place. In the pileus, the greatest expansion took place at its periphery, and there was little or no expansion in its central portion. Stipe section, from the growing zone elongated more rapidly than form any other part. Cell elongation in the growing zone of the stipe was roughly parallel to that of the fruiting body.
