Average reduction of leaf area (%) at the ear layer, the above ear layer, and the ear and above layers around the tasseling stage that resulted from the water deficits during 2014–2016.

CK, well-irrigated treatment; V6−8, water deficit during the 6–8-leaf stage; V9−12, water deficit during the 9–12-leaf stage; V13−T, water deficit from the 13-leaf stage to tasseling stage, R1−2, water deficit from the silking stage to blister stage. ∗∗ and ∗∗∗ indicate significance at P < 0.01 and P < 0.001, respectively; ns indicates no statistically significant relationship.
