(a) The relationship between total plant leaf area and time from
transplanting in onion cv. 'Hysam' at different temperatures under elevated and
normal CO
2
concentrations (532 and 374
mol/mol CO
2
, respectively). The arrows
denote the time of bulbing. The points are the means of nine replicates and the
lines are fitted logistic curves (from Wheeler
et al

Applied Biology
). (b) The relationship between total crop dry weight of onion cv.
'Hysam' at the time of bulbing and the mean temperature from transplanting to
bulbing at elevated (
) CO
2
concentrations (from Daymond
et al
