Leaf elongation rate during the ECE (A, C) and during the recovery period after the ECE (B, D) as a function of the relative soil water content (RSWC) of two perennial grass species, D. glomerata (A, B) and H. lanatus (C, D). Blue and red symbols correspond to 390 ppm and 520 ppm atmospheric CO2 concentration, respectively. Squares correspond to control treatments (390 Con and 520 Con), for which only mean values of the three periods are shown. Blue triangles and dotted blue lines correspond to ECE treatment at 390 ppm CO2. Red triangles and solid red lines correspond to ECE treatment at 520 ppm CO2. Mean ±SD are shown (n=3). For 390 Con and 520 Con, horizontal (RSWC) and vertical (LER) SD are shown.
