Morphological observation of the 6th internode cells of d2014 and WT at the 6-leaf stage. a Cross-section of cells of d2014 and WT. The arrows point to the vascular bundle (VB); N represents the total VB numbers. The magnification times are 20 ×. Bar = 150 μm. b Longitudinal section of cells of d2014 and WT. The magnification times are 20 ×. Bar = 200 μm. c The statistics of VB number for the fixed center cross section. ** indicates the VB numbers in d2014 were significantly reduced at P ≤ 0.01 level
