Measurements of phenology (development of new shoots) were undertaken in the open-top chambers and outside plots in the spring of 1989 at Headley, Chatsworth and Glendevon. No significant differences were found between phenology in ambient or filtered air. Shifts in time of flushing towards earlier shoot development within the chambers were apparent between outside plots and trees in open-top chambers. These differences became more apparent with increasing latitude north.
