 In: Plant and Soil v. 60, no. 3, p. 385-39782-766243Summary: A mixture of gluconic acid and two unidentified organic acids, isolated from the culture filtrate of Fusarium culmorum, grown in glucose-limited continuous culture, were found to be highly toxic to growth of barley seedlings. A concentration of 900 mu-g/ml of the acid totally inhibited germination of barley seeds, with lower concentrations greatly inhibiting growth and development of germinated seeds. Root extension and root-hair production were inhibited at a concentration of 450 mu-g/ml of the acids, but the number of roots per seedling was increased. Toxicity of the acids was promoted at low pH
