Effect of drought on relative water content (RWC) in the fifth leaf and spike organs. RWC was measured in the fifth leaf (a), awn (b), lemma (c), and palea (d) over the 4-day drought treatment during grain filling. Significant differences between days are indicated with lower case letters (stressed plants). For control plants, RWC did not differ significantly between days in any organ. Data are presented as the mean of three replicates ± SE. We used SigmaPlot 10.0 (Systat Software Inc., San Jose, CA) to make the figures
