Wounding
This is a way to stimulate rooting by exposing the inner part of a stem. Examples of wounding include the bare moist end of a cutting or making a notch when layering a stem.
Wounding Deliberately cutting plant stems to increase root formation.
Weeping Dropping conspicuously, pendant.
Whorled An arrangement of three or more structures arising from a single node.
Air layering: Wounding a plant's stem and wrapping it in a consistently moist medium to encourage it to grow new roots in that area to support the plant.

With many species, wounding the stem slightly encourages rooting. Remove a very thin layer of bark from the reverse side of one of the buds on the shoot that is to be layered and apply a little rooting hormone to the wounded area.
CODIT is the model used to visualize internal tissue structures and the changes which occur inside them when wounding takes place.
Although oozing often is associated with wounding or pruning, it's unknown whether the tree is invaded upon injury or if the infectious microorganisms are already present.
Compartmentalization acts to limit any decay that results from wounding to only the tissue present at the time of wounding. If compartmentalization is successful, decay will not spread into new healthy tissue that forms after the wound occurs.
Alex Shigo, a forest pathologist, has found that, when wounding occurs, a deciduous tree isolates the injury by forming phenolic compounds. Conifers form terpenes.
Air layering is a means of propagation whereby a part of a woody plant is induced to develop roots by wounding the stem of the plant and enclosing it in moist moss.
around wounded areas, walling off or compartmentalizing the wounds. Compartmentalization limits any decay that results from wounding, or from the natural death of branches. Use pruning techniques that minimize plant wounding and speed wound closure.
Air layering- Inducing root development on an undetached aerial portion of a plant, commonly by wounding it, treating it with a rooting-stimulant, and wrapping it in moist material under a waterproof covering, ...
Simple layering is accomplished by bending a branch to the ground, adding some soil over the middle portion, and then anchoring it in place with a stone. Wounding the branch can oftentimes help encourage the rooting process.
Deciduous trees should be wired after their leaves have matured, in early summer, and the wires removed in autumn to avoid wounding the bark.
For fruit infection to occur, wounding is not necessary; however, when wounds are present, they are colonized rapidly by the fungus.
