Here’s a detailed comparison of seedlings vs. rooted cuttings for Aquilaria/agarwood propagation, highlighting the advantages and disadvantages of each method:
1. Seedlings (Sexual Propagation)
Advantages
- Genetic diversity:
- Seeds produce genetically varied plants, which increases resilience to pests, diseases, and environmental stress.
- Lower initial cost:
- Seeds are generally cheaper than buying or preparing cuttings.
- Ease of storage and transport:
- Dry seeds are easier to store and transport than live cuttings.
- Better root system development:
- Seedlings typically develop a strong taproot, improving stability and drought tolerance.
Disadvantages
- Longer time to maturity:
- Seedlings take 5–7 years or more before they are ready for resin induction or harvest.
- Variable growth and quality:
- Genetic variation can result in uneven growth, resin quality, or resin yield.
- Higher nursery care initially:
- Seed germination is sensitive to fungal infections, moisture stress, and handling.
- Unpredictable resin potential:
- No guarantee that all seedlings will produce high-quality resin.
2. Rooted Cuttings (Asexual / Vegetative Propagation)
Advantages
- Genetic uniformity:
- Ensures clones of high-yield, high-resin parent trees, providing predictable growth and resin quality.
- Faster establishment:
- Rooted cuttings can grow faster initially than seedlings and reduce time to first resin induction.
- Uniformity in plantation:
- Easier management for fertilization, pruning, and resin induction, as trees grow at similar rates.
- Selection of superior traits:
- Allows propagation of trees with high oil content or disease resistance.
Disadvantages
- Lower survival rate initially:
- Cuttings are more sensitive to water stress, pathogens, and handling than seedlings.
- Higher labor and material costs:
- Rooting requires nursery facilities, hormone treatments (auxins), and skilled labor.
- Limited genetic diversity:
- Clonal plantations are more susceptible to pests and diseases if monocultures dominate.
- Requires healthy mother plants:
- Only available if high-quality, disease-free parent trees exist.
3. Summary Table
| Feature | Seedlings | Rooted Cuttings |
|---|---|---|
| Genetic diversity | High | Low (clonal) |
| Cost | Low | Moderate–High |
| Survival rate | Moderate–High | Moderate (requires care) |
| Growth rate | Slower | Faster initially |
| Resin quality uniformity | Variable | Predictable |
| Time to resin induction | Longer | Shorter |
| Labor & skill | Low | High (nursery skills required) |
| Disease/pest resilience | Higher | Lower if monoculture |
4. Key Takeaways
- Seedlings: Ideal for smallholders, genetic diversity, and long-term ecological resilience.
- Rooted cuttings: Best for commercial plantations targeting uniform high-value resin production and faster returns.
- Hybrid approach: Use seedlings for long-term genetic diversity and cuttings for core high-value blocks to balance risk and productivity.
