Healing and regeneration are critical for sustainable resin production. After induction (mechanical, microbial, or chemical), the tree must recover and continue growth to allow future resin formation.
1. What Is Healing & Regeneration?
- Definition: The tree’s natural process of repairing wounds, closing resin zones, and restoring vascular function.
- Purpose:
- Maintain tree health
- Enable repeated induction cycles
- Ensure long-term resin yield
Think of it as the tree recharging after defending itself.
2. Stages of Healing
| Stage | Description | Farmer Observation |
|---|---|---|
| Immediate (0–2 weeks) | Wound sealing, sap exudation | Sticky sap or resin around wound; tree leaves remain healthy |
| Early (2–6 weeks) | Callus formation | Light green/white tissue covers wound edges |
| Intermediate (1–3 months) | Resin polymerization continues | Resin zones develop under callus; tree may slow new growth temporarily |
| Late (3–12 months) | Full regeneration | Callus fully covers wound; tree resumes growth; resin fully polymerized in core |
3. Factors Affecting Healing & Regeneration
| Factor | Effect |
|---|---|
| Tree age & diameter | Older, thicker trees heal slower but produce more resin |
| Wound size & depth | Deep/wide wounds → slower healing |
| Induction intensity | High chemical/microbial stress → longer recovery |
| Environmental conditions | Drought or extreme temperature slows regeneration |
| Tree health | Healthy trees → faster, stronger regeneration |
4. Farmer Tips
✔ Give trees sufficient recovery time between induction rounds (3–6 months for moderate wounds)
✔ Avoid over-wounding or excessive chemical stress
✔ Support tree health with fertilization, watering, and pest control
✔ Monitor leaf growth, new branches, and wound closure
✔ Record resin zone formation and healing progress for each tree
Farmer Key Message
“A tree that heals well produces resin repeatedly.
Respect its recovery — over-stressing reduces both growth and future resin yield.”
