A-D: 3rd day under light illumination (A-D, the 2,4-eBL concentration was 0, 2×10-11, 2×10-9, 2×10-7 mol/L); E-H: 3rd day under dark illumination (E-H, the 2,4-eBL concentration was 0, 2×10-11, 2×10-9, 2×10-7 mol/L); I: light culture of the primary root to the earth angle; J: dark culture of the primary root to the earth angle. Scale: 1 cm. * indicates that there is a significant difference with the control group (p<0.05); ** indicates that there is a highly significant difference with the control group (p<0.01). |
