Abstract

Long intermittent exposures ofAraucaria cunninghamii to SO₂ and NO₂ produced complex interactions with effects on resource allocation and plant morphology. Exposure to NO₂ decreased chlorophyll concentrations but increased stem diameter and shoot fresh weight, in an apparent compensatory response, altering the growth form of the tree. The effects of NO₂ were counteracted by the additional presence of SO₂, although SO₂ alone had little effect.
