From: A combination of scanning electron microscopy and broad argon ion beam milling provides intact structure of secondary tissues in woody plants

Figure 1

Scanning electron microscopy results of the broad argon ion beam (BIB)-milled radial sections of Pinus densiflora (a) and illustration of the BIB milling process (b). Using the BIB milling process, a broad cross-section from phloem to xylem was obtained without cutting defects and distortions. The resin canal can be easily distinguished from the neighboring tracheids as the resin shows high contrast in the back-scattered electron image. A red-boxed area corresponds to Fig. 2a. Ca, cambium; Ph, phloem; R, resin canal; T, tracheids; Xy, xylem. Scale bar = 100 µm.
