โœฆ Synopsis

The growth rate of rice coleoptiles is increased by low concentrations of ethylene, especially in oxygen concentrations lower than air; carbon dioxide enhanced this response. C2H4 is produced by rice seedlings, and this production is also enhanced by carbon dioxide. Ethane and propane were produced in trace amounts but were inactive in growth stimulation as were also methane, propylene, and butane.

Ethylene stimulated growth of rice coleoptiles in the dark and after an irradiation with red light. The red-light inhibition of rice-coleoptile growth was more pronounced when only endogenously evolved C2H 4 was involved than it was under Celia-free (C~H 4 removed) or C2tta-saturated (20 ppm Cell a
