Abstract : 2,4-Dichlorophenoxyacetic acid (2,4-D) stimulated ethylene production from light-grown corn (Zea mays L. cv. XL-15) and soybeans (Glycine max Merr. cv. Hawkeye). Ethylene inhibited growth of corn and soybeans, but a reversal of the ethylene effect could not be clearly demonstrated using the competitive inhibitor, carbon dioxide. Ethylene did not mimic the ability of 2,4-D to cause growth curvatures. It was concluded that ethylene played a role in the activity of sublethal amounts of 2,4-D. (Author)
