Fig. 1. Changes in leaf water potential of (A) an indica/indica (I/I) hybrid rice Shanyou 63 and two japonica/indica (J/I) hybrids, (B) Ce 03/Yangdao 4 and (C) PC 311/Zaoxiandang 18, during the first 28 d after withholding water. WW, MD, and SD are well watered, moderate water deficit, and severe water deficit, respectively, during grain filling. Measurements were made on the flag leaves at predawn (0600 h) and at midday (1130 h). Vertical bars represent ± standard error of the mean (n = 6) where these exceed the size of the symbol.
