View larger version (31K): [in this window] [in a new window]   Fig. 1. Total plant length versus days after emergence for potato plants grown at ambient (370 µmol mol–1) and elevated (740 µmol mol–1) [CO2] at six different levels of water stress (expressed as % of control irrigation). Lines are the fit of the Gompertz equation (Table 2). Data points are averages of measured length of five plants (standard deviations shown).

Individual final leaf area [Xf, (A) and (C)] and leaf expansion rates [Rmax, (B) and (D)] versus irrigation amounts for mainstem and apical stem leaves on potato plants grown at 370 and 740 µmol mol–1 [CO2]. Error bars are standard deviations of five plants per observation. Lowercase letters indicate significantly different regression coefficients.
