I cannot give you the specifics you're looking for, but the last question's answer is a yes.

So it's nothing more than healing?

I don't know how plants heal but they miraculous at staying alive.

There was some rot in one of the branches I was trying to stop. The plant took over and aborted the the area (see fissure in photo)

AS for treatments, everyone has their remedies. Cinnamon, fungicide and so. Me, I don't add anything. Just make sure there is plenty of air circulation to speed callusing.

Very interesting.

Can the wound form feeder roots? I’d like more feeder roots on mine.

The contrast between the plant and animal kingdoms is fascinating! There are many parallels. Sex evolved in both to mix up the gene pool, both plants and animals evolved to be independent of free water for fertilization to occur (fish, frogs and algae, mosses, ferns, cycads and ginkgos all need liquid water for fertilization to occur; higher plants and animals do not depend on water for fertilization), Here is a big difference, HEALING ONLY occurs in the ANIMAL kingdom, plants SEAL OFF the dead tissue and manage to grow around it. I learned this having to deal with DEER in NJ and the annual rut. Most all my trees eventually got rutted in a season. Almost ALL survived the rut, the damage will NEVER HEAL but the tree will "compartmentalize" the damage, and grow, new living tissue over the dead tissue. Hope this answers your question.

To answer the question "Can the wound form feeder roots?" and presumably you're still talking about a wounded caudex, the answer is 'YES, under favorable conditions'. (BTW - all roots start out as feeder roots. As they grow/ thgickin, they become incapable of growing the almost microscopically fine 'hair roots' which do all the plant's heavy lifting in terems of water/ nutrient uptake.) Wounds are initially covered by callus, which consists of groups of unorganized heterogenous (dissimilar) cells that arise from several source cells in the plant's vasculature, cortex, or cambium. Stimulation of tissues capable of producing callus is caused by a mixture of two growth regulating chemicals, auxin and cytokinin. Most callus tissue is pluripotent, meaning the callus tissue is fully capable of morphing into organized cells (meristematic regions) which in turn are capable of producing new stems or roots, depending on what stimuli they receive.
