Fig. 5. Changes in ¹⁴C partitioning in the stems (A and B) and grains (C and D) 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), during the grain filling period (pot experiment only). 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. The experiment was conducted at Yangzhou University farm, Jiangsu Province, China in 2001.
