Abstract

The observation that riboflavin overcomes the chlorosis response of higher plants to amitrole was confirmed. Amitrole was shown to be decomposed in the presence of riboflavin and light. It is suggested that this decomposition proceeds by a free radical mechanism, either in the culture medium or in the plant.
