Early Resin Indicators in Agarwood – Spotting Resin Formation During BarIno™ Induction
After inoculation, resin begins to form gradually around infection points. Recognizing early visual, olfactory, and sap cues is critical for assessing tree response, scheduling follow-up inoculations, and predicting resin quality.
1. Color Changes
What to Observe:
- Initial yellowish-brown streaks in the wood near inoculation points
- Gradual darkening to reddish-brown or black over weeks to months
- Resin-rich zones often contrast with surrounding sapwood
BarIno™ Tip:
- Early spotting is usually subtle
- Avoid removing large wood sections—use a small probe or observation window
2. Scent Development
What to Observe:
- Mild sweet, woody, or resinous aroma emanating from wounds
- Aroma intensity increases as resin polymerizes
- Distinctive terpene-rich notes appear before wood darkens
BarIno™ Tip:
- Early scent is not as strong as mature oud
- Scent confirms active defense metabolism and effective fungal colonization
3. Sap Flow & Consistency
What to Observe:
- Slight thickening or cloudiness of sap near inoculation points
- Sap may appear viscous, amber-tinted, or slightly sticky
- Healthy resin-producing sap maintains slow, steady flow
BarIno™ Tip:
- Sudden clear sap or excessive oozing may indicate poor colonization or over-infection
- Monitor sap flow weekly during early induction
4. Timing of Early Indicators
| Indicator | Typical Onset | Notes |
|---|---|---|
| Color change | 4–6 weeks after inoculation | First visible resin streaks |
| Aroma | 6–8 weeks | Mild but detectable near wound |
| Sap viscosity | 2–4 weeks | Early resin precursors in sap |
Note: Timing varies by DBH, tree age, seasonal conditions, and BarIno™ product phase.
5. Monitoring Protocol (Farmer-Friendly)
- Mark inoculation points immediately after treatment
- Weekly inspection for color, sap, and scent changes
- Record observations in logbook: color progression, scent strength, sap condition
- Adjust follow-up products (FusaTrinity™, FusaBlaze™) based on early indicators
6. BarIno™ Principle
Early resin indicators are the tree’s “status report.”
Observing color, scent, and sap changes allows precise timing of amplification and densification phases, ensuring high-quality agarwood while protecting tree health.
