From: Response of stalk lodging resistance traits, yield and quality of silage maize to high density
Effect of high-density planting on the morphology and mechanical traits of silage maize. D1, D2 and D3: Planting densities of 150,000 plants \(\hbox {ha}^{-1}\), 180,000 plants \(\hbox {ha}^{-1}\) and 210,000 plants \(\hbox {ha}^{-1}\), respectively; M1, M2 and M3: SheyuD1616, Dajingjiu 23 and Xianyu 1225, respectively; Horizontal coordinates (0, 10, 16, 20, 26, and 43): Growth stages corresponding to V6 (6-leaf stage), V9 (9-leaf stage), V12 (12-leaf stage), V15 (15-leaf stage), VT (tasseling stage), and R2 (blister stage), respectively. (A) Effect of high density on plant height, ear height and ear ratio. (B) Effect of high density on upper ear leaf area, ear leaf area, and lower ear leaf area. (C) Effect of basal 3rd internode on maximum diameter, minimal diameter, and stalk cross-sectional area. (D) Rind Penetration of basal internodes. (E) Bending strength of basal internodes. Different lowercase letters represent significant differences between different silage maize varieties at different planting densities at the 0.05 level. ns represents no significant level. *p<0.05, ** p<0.001.
