vascular cylinder การใช้

The main target of this pathogen is the central vascular cylinder of the roots.
In roots, the cork cambium originates in the pericycle, a component of the vascular cylinder.
In many seedless vascular plants, the endodermis is a distinctly visible layer of cells immediately outside the vascular cylinder ( stele ) in roots and shoots.
It moves between, rather than through, cortical cells towards root apex, turns at the meristem, and migrates back to the vascular cylinder in the zone of cell differentiation.
Although it is composed of non-vascular parenchyma cells, it is still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues it surrounds.
