Yield vs. Tree Longevity Trade-Offs in Agarwood Induction – Balancing Resin Production with Tree Health
Agarwood induction involves controlled stress, fungal colonization, and chemical priming. While these increase resin yield, over-induction or aggressive treatment can reduce tree longevity. Understanding this trade-off ensures sustainable, high-quality production.
1. The Trade-Off Explained
| Goal | Effect on Tree | Outcome on Resin Yield |
|---|---|---|
| Aggressive induction (high point density, short time-gaps, multiple products) | High stress → cambium damage, necrosis, reduced lifespan | Maximum short-term resin, but uneven quality, risk of tree loss |
| Moderate induction (DBH-based spacing, proper sequencing, optimal time-gaps) | Tree remains healthy → long productive life | Slightly lower immediate yield, but consistent, high-quality resin over multiple cycles |
| Minimal induction (low density, limited products) | Very low stress → minimal impact on longevity | Low yield, may take years to accumulate commercial-quality resin |
Principle: Maximizing yield often accelerates tree aging, whereas prioritizing longevity may slow resin accumulation.
2. Key Factors Affecting the Trade-Off
- DBH & Age:
- Small/young trees: aggressive induction → high mortality
- Mature trees: tolerate more points, higher yield without compromising longevity
- Point Density & Depth:
- Too many inoculation points → overlapping stress → necrosis
- Too shallow/deep → ineffective resin, wasted effort
- Time-Gap Management:
- Short gaps → stress accumulates → reduced lifespan
- Proper spacing → recovery and sequential resin production
- Product Choice & Sequencing:
- Dual-pathway induction (FusaTrinity™, Harmonia™) boosts yield but requires tree readiness
- Densification products (ResinRush™, FusaBlaze™) must follow successful earlier phases
- Environmental Stressors:
- Drought, pests, or extreme temperatures exacerbate stress and reduce longevity if combined with aggressive induction
3. Managing the Trade-Off
- Plan induction by DBH and tree health
- Limit maximum inoculation points per tree based on size and vitality
- Stagger cycles for larger plantations to avoid over-stressing all trees simultaneously
- Monitor resin indicators (color, viscosity, aroma) rather than relying solely on calendar intervals
- Prioritize high-value trees for aggressive induction; smaller trees for gradual induction
4. Farmer-Friendly Analogy
Yield vs. longevity is like harvesting fruit from a tree: picking too many early can produce a lot now but weaken the tree, whereas picking moderately ensures a long, sustainable harvest.
