Helminthosporol (H-ol) and helminthosporic acid (H-acid) were effective in promoting elongation of leaf sheaths of rice, Japanese barnyard grass and dwarf maize (d-2 and d-5) and of hypocotyls of taisai (Brassica chinensis), but inactive in leaf sheaths of oat and wheat, hypocotyls of sesame and morning glory (Pharbitis nil) and epicotyls of Pharbitis and dwarf and tall peas. On the elongation of the leaf sheath of maize d-1, H-ol was promotive but the activity of H-acid was doubtful. On hypocotyls of lettuce and daikon (Raphanus sativus), only H-acid was active. Multiplication rate and size of fronds of Lemna perpusila were not affected by either of the substances. Compared with gibberellic acid for the effect on the shoot growth. H-ol and H-acid were weak in activity and narrower in the scope of plants that responded. H-ol and H-acid characteristically promoted the elongation of the primary root. Comparative effectiveness of H-ol and H-acid varied with plant species or parts examined.
