Figure 9. Characteristics of the primary root tip procambia of four taxa (1–4) in the Poaceae as seen in enhanced section images and 3D constructions. (A) Views of the basipetal face of the vascular initials layers, (B) oblique perspective of 3D constructions of the central initials and plerome cells (shades of green), (C) transverse images of the VC at 100 µm from the RCJ, and (D) 3D images from the primary root tips of the LMX(s) and two pericycle cell files associated with their plerome and vascular initials layer. Scale bar = 50 µm.
