Extract

It has been reported by Carroll (1,2) that light activated riboflavin will counteract 2,4-D inhibition, presumably due to an inactivation or destruction of the 2,4-D molecule. Hansen and Buchholtz (7) found that light activated riboflavin would inactivate the 2,4-D molecule in vitro and it appeared that 2,4-dichlorophenol was one of the decomposition products. Galston (3, 4, 5) has shown that riboflavin may act as a photo-receptor and a hydrogen carrier in the oxidation of indol-3-acetic acid, the reduced riboflavin being re-oxidized by the air. It would appear, therefore, that riboflavin may play an important role in the breakdown of growth substances in the plant.
