RESUMO
Application of polyethylene glycol or phenylmercuric acetate to intact bean (Phaseolus vulgaris L., cv. Red Wade) roots inhibited passage of phosphorus across the roots to the xylem. The same results occurred for foliar application of phenylmercuric acetate when time was allowed for absorption and distribution of the chemical in the plant. For both chemicals the inhibition of phosphorus was proportional to or greater than any accompanying restriction on water flow across the root.
