To test the hypothesis that growth-CO(2) concentrations affect stress susceptibility, leaves of poplar trees (Populus alba x tremula) grown under ambient or about twofold ambient CO(2) concentrations were subjected to chilling temperatures at high light intensities or were exposed to paraquat. Photosynthesis was less diminished and electrolyte leakage was lower in stressed leaves from poplar trees grown under elevated [CO(2)] as compared with those from ambient [CO(2)]. Severe stress caused… CONTINUE READING
