• The penetration of naphthaleneacetic acid (NAA) into pear (Pyrus communis L. cv. Bartlett) leaves as influenced by selected treating solution and environmental factors was studied under defined and controlled conditions. Penetration through the adaxial leaf surface was linear with time, whereas, movement through the abaxial surface was rapid initially and then the rate diminished with time. Penetration through both leaf surfaces was proportional to external concentration and was temperature dependent. More NAA penetrated at pH values below than above the pK_a. Light ( 1000 ft-c) stimulated NAA penetration. The light enhanced penetration of NAA was depressed by 3-tert-butyl-5-chloro-6-methyluracil, 3-(p-chlorophenyl)-1,1-dimethylurea, phenylmercuric acetate, 2,4-dinitrophenol, carbonylcyanide m-chlorophenylhydrazone and carbonylcyanide p-trifluoromethoxyphenylhydrazone. We concluded that NAA penetration was controlled by both physical and metabolic factors.
