FIGURE 5.

Longitudinal-sectional micrographs (A) of the ovary at 5th kernel ring, stained with toluidine blue at 4 days after pollination, and grain-filling dynamics of inferior (B) and superior (C) kernels in 2015. CK, well-irrigated treatment; V₆₋₈, water deficit during the 6–8-leaf stage; V₉₋₁₂, water deficit during the 9–12-leaf stage; V_13−T, water deficit from the 13-leaf stage to tasseling stage, R₁₋₂, water deficit from the silking stage to blister stage. Values with different letters are significantly different at P < 0.05.
