Here is the Resin Development Timeline for Fusarium oxysporum as a biotic inoculant in Aquilaria spp.:
Resin Development Timeline – Fusarium oxysporum Inoculation
| Timeline | Resin Development Stage |
|---|---|
| 0 – 2 Weeks | Initial Infection Phase |
| – Fungus colonizes xylem tissue | |
| – Localized vascular stress initiated | |
| – Host defense response begins (minor browning) | |
| 2 – 4 Weeks | Early Resin Formation |
| – Activation of secondary metabolism | |
| – Accumulation of sesquiterpenes and chromone precursors | |
| – Visible browning near inoculation points | |
| 1 – 3 Months | Active Resin Induction |
| – Fungal colonization expands along vessels | |
| – Chromone-rich oleoresin begins to form | |
| – Distinct woody/spicy scent detectable from resinized tissue | |
| 3 – 6 Months | Resin Maturation Phase I |
| – Thickening of oleoresin deposits | |
| – Color shifts from light brown to dark brown or black | |
| – Wood begins to gain weight and aroma concentration increases | |
| 6 – 12 Months | Peak Resin Development |
| – Maximal yield observed in well-infected trees | |
| – Highly resinous zones with high chromone and sesquiterpene concentrations | |
| 12 – 18 Months | Stabilization Phase |
| – Colonization slows or stabilizes | |
| – Possible fungal self-limitation by oleoresin barrier | |
| – Harvest window for optimal yield and fragrance intensity |
Key Notes:
- Fusarium oxysporum inoculation typically leads to gradual but high-quality resin development.
- Aromatic profiles are rich in chromones and earthy-woody volatiles.
- Co-inoculation with mild chemical stressors (e.g., MgCl₂, MnO₂) may accelerate early-stage resin onset.
- Peak harvest window is usually between 6–18 months post-inoculation.
