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
