Abstract
Ethylene is produced by cultured radish roots in amounts large enough to be physiologically important. When roots were grown in controlled atmospheres, applied ethylene was generally inhibitory to elongation, lateral root initiation, and cambial activity. 1% CO2 similarly affected roots not given ethylene. In contrast, elongation and lateral root production of ethylene-treated roots were stimulated by 1% CO2. The results suggest that the often-observed stimulation of root growth by CO2 is due to an interaction with endogenous ethylene.Keywords
