洋菇引種試驗

Abstract

筆者等1953年至1967年引進洋菇品種計有21種之多，其中白色品種有17個品系，乳白色品種有2個品系，褐色品種亦有2個品系。所有各品種中以乳白色品種子實體最大，褐色品種次之，白色品種較小，但各品種間因受栽培環境因子之影響住往子實體大小之差異很大。菌絲之生長速度則以褐色品種最快，乳白色品種次之，白色品種稍慢，而白色品種中則以303號品系最快。子實體之產量平均以褐色品種較高，惟各品種最高產量均可達到30kg/坪左右，同一品種因栽培場所或年度不同其間產量差異極大。 各品種加工談開罐之色澤均可合乎外銷規格，香味方面褐色品種202及白色品種208,M2,S.W-34等品種較佳。 Some physiological and morphological characters of varieties or strains of the introduced foreign cultivated mushroom were observed, of twenty one strains introduced, seventeen strains belong to variety whose color are white, two are cream, and two are brown. Size of fruiting body varied with each other, Cream variety was the biggest, Brown variety was the next. The rate of the growth of mycelium also varied among the strrins, Brown variety faster than the other two, and followed by the cream variety. Brown variety produced the highest yield of the fruiting body among three. The biggest yield of the strain of each variety was about 3Okg/6x6ft. The quality of each strain for canned mushroom industry was also discussed.
