• Vapors of mercury and iodine induce abscission in Coleus explants and color-ripening in immature bananas. Their effects on abscission are antagonized by an auxin, a-naphthaleneacetic acid, and by carbon dioxide. Alkyl derivatives of mercury and iodine are less active than the parent element, a situation parallel to the reduced activity of the homologs (alkyl derivatives) of ethylene and acetylene. Chemical differences between the elements and olefins preclude a direct ethylene-like effect. Hence it is suggested that their activities are mediated by endogenous ethylene, and that their primary action leads to increased biosynthesis.
