The cambial zone begins to form a barrier zone (red tissue above) along the inner edge of the cambium. This barrier zone is rich in suberin, has less lignin and fewer conducting elements than previously formed tissue, and more axial parenchyma. This combination of materials makes the barrier zone extremely resistant to movement of organisms out into new tissue formed after wounding.
