Fig. 1. Changes in leaf water potentials of two two-line indica hybrids of rice, Pei-Ai 64S/Yangdao 6 (A and C) and Pei-Ai 64S/E 32 (B and D), in the pot (A and B) and field (C and D) experiments during the first 29 d after withholding water. WW, MD, and SD are well watered, moderate water deficit, and severe water deficit during grain filling. Measurements were made on the flag leaves at pre-dawn (0600 h) and at midday (1130 h). Vertical bars represent ± SE of the mean (n = 6) where these exceed the size of the symbol. Both experiments were conducted at Yangzhou University farm, Jiangsu Province, China in 2001.
