Abstract
Bean plants, Phaseolus vulgaris, grown under greenhouse conditions were decapitated at the 2d internode, and the cut surface treated with 2% indoleacetic acid in lanolin. Analyses of the carbohydrate fractions on the entire plant, using the eerie sulfate method, indicated a translocation of carbohydrates toward the point of treatment and a condition causing simple carbohydrates to be condensed to complex poly-saccharides. Dry weight differences between the control and treated plants, as well as the chemical nature of the treated stems, suggested respiratory increases following stimulation by indoleacetic acid.
