Three cytokinins and their ribosides were tested in conjunction with brassinosteroid (BR) for their effects on ethylene production in etiolated mung bean ( Vigna radiata L. Rwilcz cv. Berken) hypocotyl segments. When varying concentrations of BR were tried in combination with a fixed amount of kinetin (10 μ M ), there was an increase in ethylene production with increasing concentrations of BR up to 3 μ M , and a decline beyond. A stimulation in ethylene production was observed with increasing concentrations of each of the cytokinins used. However, when applied in conjunction with 3 μ M BR, all cytokinin concentrations produced similar stimulatory patterns. When 3 μ M BR or 10 μ M 6‐benzylaminopurine (BAP) was applied in conjunction with increasing concentrations of IAA, there was a stimulation in ethylene production with increasing concentrations of IAA. However, 3 μ M BR and 10 μ M BAP together with varying concentrations of IAA failed to alter the level of ethylene production.
