Abstract
Gibberellins As-4 Ag-9 and A(24) were isolated and identified from the new gibberellin-producing fungus, Phaeosphaeria sp. L487 (Loculoascom ycetes), cultivated in a chemically defined medium; their yields from the culture filtrate were ca. 1.7, 0.3, and 0.4 mu g/ml, respectively. Gibberellins A(4) and A(9) significantly stimulated the hypocotyl gro wth of Chinese cabbage seedlings at a very low concentration of less t han 0.01 mu g/ml.
