  1. 1)The treatments were well-watered (WW), moderate soil-drying (MD) and severe soil-drying (SD) during young panicle development
  2. 2)Data are means ± standard error of six independent measurements and values with different letters indicate statistical difference at P = 0.05 within the same row
