FIGURE 3

Transverse section of ear peduncle at 49 (A1–E1) and 65 (A2–E2) days after sowing (DAS); the area of the marginal vascular bundle (VB) (F) and central VB (G); and the total vascular bundle number in ear peduncle (H) and ear peduncle area (I) at 65 DAS (12 days after silking). The marginal VB, closely arranged at the edge of the ear peduncle, was consistently undeveloped and was small in size. The central VB, scattered and distributed in the center of the ear peduncle, was consistently well-developed and had a large size. 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. Values with different letters are significantly different at P < 0.05.
