Shoots of three cultivars of Petunia hybrida Vilm. of differing ozone (O/sub 3/) and sulphur dioxide (SO/sub 2/) sensitivity were exposed to O/sub 3/ and SO/sub 2/ in closed chambers for observation of pollutant absorption through the stomates and adsorption by leaf surfaces. The cultivar least sensitive to injury, 'Capri', absorbed the least ozone or SO/sub 2/ but absorbed the most. The sensitive 'White Cascade' had the opposite sorption pattern. Absorption of the individual gases was generally less from the mixture, whereas adsorption rates were similar whether the gases were supplied singly or in mixture. The existence of substantial differences in surface adsorption could introduce error in measurements of pollutant absorption by leaves.
