The plexus of vascular bundles in the nodes of grasses is notoriously complex, where long axial bundles pass through a network of transverse bundles. The xylem pathways for water in maize stems have been investigated anatomically and with dye and particulate tracers, revealing some of the details of this complexity. Only approx. 3 % of axial vessels pass through nodes without being interrupted by end walls. Axial bundles at nodes differ from those in internodes in having the metaxylem and...[Show more]
