My comments

Is there any coverage of this or related topics elsewhere in Wikipedia? e.g. plant disease resistance has some relevant content
As stated in both rejections this reads like an essay.
Perhaps the scope would be better as "wound response in plants" - jasmonic acid is mentioned, which if I recall correctly is involved in promoting the production of chemical and other anti-herbivore defences in the same and neighbouring plants.
I find it rather rambling; I think it needs a tighter focus and better organisation.
I'd question the accuracy of the material about Darwin, but the whole section isn't relevant.
I am an amateur botanist with limited knowledge of plant physiology - I should be able to read this and be informed, but I wasn't - see tighter focus and better organisation above.

To propose an outline

What is wounding? - a breach of the protective outer layers of a plant - relevant terms include epidermis, cuticle, bark, periderm and perhaps more.
What threats to the plant does wounding produce? - e.g. loss of moisture, exposure to pathogens.
What are the short term responses?
- a) signalling to promote anti-herbivore defences (also anti-microbial defences?)
- b) sealing of the wound
- c) abscission of the affected organ
What are the long term responses? e.g. callus formation

In general, think of two questions - what happens? and how is it regulated? and address them in that order (or interleaved - event, regulation, event, regulation, ...)

The mentions of sucrose and callus culture seem either extraneous or too short. The use of sucrose as a transport molecule is not specific to wounding, but there could be something to say about the regulation of sucrose (production and) transport to supply a carbon source to the wound sight. The behaviour of callus cells is tissue culture is relevant only to the degree that it is used to shed light on how callus formation works in vivo.

I hope that this is constructive commentary.

Dedifferentiation

The cited source (a press release, which is not ideal) says that "typically" dedifferentiation is the source of pluripotent cells involved in wound healing. Giving the availability of lateral meristem in woody plants I would not be surprised if that in a significant proportion of cases dedifferentiation is not involved. Even in non-woody plants it is conceivable that patches of meristem are left behind for use in the even of trauma. I think that at the least better sourcing is needed.
