Fig. 3. Changes in chlorophyll content in the flag leaves 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 grain filling period. WW, MD, and SD are well watered, moderate water deficit, and severe water deficit during grain filling. Arrows indicate the start of water deficit treatments. 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.
