Fig. 1

Changes in osmolality of upmost fully-expanded leaves (a) and panicles (b), photosynthetic rate of the upmost fully-expanded leaves (c) and leaf area index (LAI) (d) of the rice cultivar YD-6 under well-watered (WW), moderate soil-drying (MD) and severe soil-drying (SD) treatments. SPD, PMC, and PF represent spikelet primordium differentiation, pollen mother cells meiosis, and pollen filling, respectively. Vertical bars represent standard error of the mean (since the panicle and leaf osmolality at the three stages showed the same tendencies, the data are presented on average of the three stages and n = 18; n = 6 for leaf photosynthetic and LAI) where these exceed the size of the symbol. The asterisk (*) represents significant difference (P = 0.05) between the MD regime and the WW regime or between the SD regime and the WW regime within the same measurement date. “ns” represents non-significant at P = 0.05 between the MD regime and the WW regime
