- Title
Coumarin effects on Glycine max hypocotyl explants.

- Abstract
Coumarin induced root formation and stimulated fresh weight production in hypocotyl explants of Glycine max L. cultured in vitro. All stimulatory effects caused by coumarin were induced within a relatively narrow range of concentrations between 1-500 μM, yielding optimum dose response curves. When coumarin was combined with kinetin fresh weight increased considerably, at optimum concentrations to a level almost as high as that obtained with NAA (10 μM) and kinetin (10 μM). Root formation, was almost completely inhibited when kinetin was added in combination with coumarin. NAA + coumarin had small stimulatory effects on fresh weight, but were inhibitory in root formation. The frequency of rooting per explant, texture and pigmentation were also affected by different treatments.
