Tree World - View Single Post - longer cuts on poor compartmentalizers| CODIT WALL4

Sticking my two bits in, Wall 4 was formed when woundwood grew over the wound. It has cambium along the outer edge of the curl at the growing front, but this new growth is arrested by pressure when it contacts the surface of the wound. The ultimate strength of this wall is a total lack of physical linkages and conductivity between the new wood and the old. I don't believe it has a lot to do with phenols and all that, but I could be wrong. It is like a waterproof layer of paint over a stain on wallpaper. The old stain is still there, but covered and it can't get out, but neither could any air or additional pathogens get in, once the seal is complete.
