Effects of volatile and gaseous metabolites of swelling seeds of pea, bean, wheat, corn cucumber, tomato, lentil, carrot, red papper and lettuce on germination of spores of five genera of fungi were found to depend rather on the fungal than on the plant genus. Germination of spores of Botrytis cinerea, Mucor racemosus and Trichoderma viride was most severely inhibited. Spores of Verticillium dahliae were less sensitive and germination of spores of Fusarium oxysporum was inhibited only in two cases. On the other hand, exudates of pea and bean stimulated germination of spores of Fusarium oxysporum. Also spores of Trichoderma viride germinated better in an atmosphere enriched with exuded metabolites of swelling lettuce seeds. When carbon dioxide produced by the swelling seeds was absorbed in potassium hydroxide, spores of Trichoderma viride and Verticillium dahliae did not germinate at all, the inhibitory effects of volatile and gaseous exudates on germination of spores of Mucor racemosus were accentuated, and also the percentage of germinated spores of Fusarium oxysporum decreased. Germination of spores of Botrytis cinerea was not influenced. Absorption of volatile and gaseous metabolites in a solution of potassium permanganate decreased in most cases their inhibitory effects, particularly in Botrytis cinerea.
研究发现，豌豆、豆类、小麦、玉米、黄瓜、番茄、小扁豆、胡萝卜、红辣椒和生菜种子膨胀时产生的挥发性和气态代谢产物对五种真菌孢子萌发的影响，更多地取决于真菌种类而非植物种类。灰葡萄孢、总状毛霉和绿色木霉的孢子萌发受到的抑制最为严重。大丽轮枝菌的孢子较不敏感，尖孢镰刀菌的孢子仅在两种情况下萌发受到抑制。另一方面，豌豆和豆类的渗出物刺激了尖孢镰刀菌孢子的萌发。此外，绿色木霉的孢子在富含膨胀生菜种子渗出代谢产物的气氛中萌发得更好。当膨胀种子产生的二氧化碳被氢氧化钾吸收时，绿色木霉和大丽轮枝菌的孢子完全不萌发，挥发性和气态渗出物对总状毛霉孢子萌发的抑制作用增强，尖孢镰刀菌萌发孢子的百分比也降低。灰葡萄孢孢子的萌发不受影响。在大多数情况下，用高锰酸钾溶液吸收挥发性和气态代谢产物会降低它们的抑制作用，尤其是对灰葡萄孢。
