Abstract
Seedlings of Betula pubescens Ehrh. (mountain birch) and Phleum pratense L. (timothy) were grown for 42 days under full light or 50% shade in the field at 12°C, and at comparable photosynthetic active radiation (PAR) levels in a greenhouse at 18°C. Plants from the four pretreatments were exposed to 78 nmol mol-1 (ppb) O3 (8 h day-1) under two temperatures (15 and 25°C), two relative air humidities (50 and 80% RH) or two CO2
