Table I. Effect of soil WD on grain loss, photosynthesis, transpiration, date of silk growth arrest, fresh weight in silks and ovaries, and soluble sugar content in silks and ovaries at SE.

GC, Growth chamber; GH, greenhouse. WD1, WD2, and WD3 represent soil WDs imposed from tasseling to 5 d after SE. Different letters within a column indicate significant differences in a Kruskal-Wallis test (P < 0.05).
