Seedlings of radish ( Raphanus salivas L. cv. Cherry Belle) and wheat ( Triticum aestivum L. cv. Starke II, Weibull) placed in air containing vapour of di‐ n ‐butyl‐phthalate accumulate phthalate to a concentration that is 10 6 times that of the surrounding air within 3 days. Particularly high accumulation is found in the cuticular and wax layers. Plants earlier found not to respond to di‐ n ‐butylphthalate (wheat) show toxic symptoms (carotenoid and chlorophyll deficiency in strong light, conco‐mittant with chloroplast destruction and swollen mitochondria) when the phthalate concentration is further increased by addition to the nutrient medium. Phthalate‐affected, white leaves lack the protein moieties normally belonging to the light harvesting complex.
