Abstract

Brassinosteroid (BR) and indole‐3‐acetic acid (IAA) were used in combination with Ca2+ in order to determine if there was a synergistic effect in the stimulation of ethylene production in etiolated mung bean (Vigna radiata L. Rwilez ev. Berken) hypocotyl segments. Ca2+ was found to act synergistically with BR. IAA or a combination of the two in promoting a stimulation in ethylene production. EDTA, which chelates Ca2+, greatly reduced the effectiveness of calcium salts in promoting ethylene production in the presene of either BR, IAA or a combination of the two. Neither K+, Mg2+ nor Mn24 (chloride salts) acted synergistically with BR and IAA.
