title: Physiological activities of helminthosporol in comparison with those of gibberellin and auxin.
abstract: Helminthosporol, a metabolic product of Helminthosporium sativum, remarkably stimulated elongation of the second leaf sheath of rice seedlings of various varieties. It also stimulated the elongation of hypocotyls of cucumber seedlings. This substance did not have any effect on the growth of peas, tomato, sunflower and the dwarf mutants of maize. This substance did not have auxin-like activities.
