Abstract

Cuttings of Populus hybrids were exposed to 0.25 ppm SO₂ for 72 h/wk for 14 consecutive weeks in 1979. In 1980, a 2nd set of cuttings was exposed to 0.12 ppm SO₂ for 72 h/wk for 6 consecutive weeks. Leaf conductance was stimulated during 72-h exposures to 0.25 ppm SO₂. Six 72 h/wk exposures to 0.12 ppm SO₂ had no effect on conductance, but induced changes in foliar water potential and osmotic potential. -from Authors
