Abstract
Culturing the hypocotyl explants from 7-day-old, light-grown seedlings of sunflower (Helianthus annuus L.) on auxin-supplemented MS medium l eads to a marked stimulation in callus induction and root initiation. NAA proved more effective than IAA for both responses. Experiments emp loying ethylene precursors (methionine and ACC) and action inhibitor ( A(g)NO(3)) revealed a significant role of endogenous ethylene levels i n auxin-induced rooting. The auxin-ethylene interaction in root morpho genesis is accompanied with specific changes in anodic peroxidase isoz ymes.
