促進洋菇孢子發芽之研究

Study on Stimulation of Spore Germination of Mushroom (Agaricus bisporus (Lange) Sing.)

1.生長發育中的洋菇菌絲所產生的新陳代謝揮發性產物，對洋菇孢子發芽有刺激作用。2.洋菇菌絲新陳代謝時所產生之揮發性代謝產物中以10 ppm濃度之acetaldehde對洋菇孢子發芽的刺激能力較同濃度的ethyl alcohol, ethyl acetate, acetone等藥物顯著。3.10 ppm濃度之iso-valeric acid與iso-amyl alcohol對洋菇孢子發芽有刺激作用，而同濃度之acetylene則無效。4.新鮮孢子對揮發性物質之處理較為敏感，易發生刺激發芽之現象。

1. Germination of mushroom (Agaricus bisporus) spore is stimulated by the volatile metabolite of the living mycelium of the same species. 2. Germination is stimulated by the treatment of 10 ppm acetaldehyde which is one of the metabolic gases of the living mycelium. No stimulating effect has been shown by the same concentration of other volatile metabolites, namely ethyl alcohol, ethyl acetate, acetone and a complex treatment of these four chemicals in same concentration of 10 ppm. 3. A concentration of 10 ppm, of iso-valeric acid and iso-amyl alcohol were shown the stimulation of spore germination, but tin evidence that acetylene was a stimulant. 4. A fresh spore is more significant on chemical treatment to stimulate the germination of mushroom spore.
