Abstract
In this phytotron experiment we investigated the influence of increase d CO2, O-3 and drought on the content of soluble proteins and some enz ymes of carbon and nitrogen metabolism. We found that the amounts of s oluble proteins and the large subunit of the rubisco per fresh weight in young oak leaves declined under conditions of increasing levels of CO2 and after temporary water stress. The activities of nitrite reduct ase and glutamine synthetase were reduced when O-3 and CO2 levels were raised. (C)1998 Elsevier Science Ltd.
