- Method / resource The developed rooting method attained 78% rooting.
- Observation Cold-stored shoots did not survive rooting.
- Observation Best rooting occurred in free-draining peat–pumice–perlite medium under controlled conditions.
- Intervention effect Well-managed watering and gradual conditioning enhanced survival and rooting.
- Intervention effect Removing basal callus before auxin treatment improved rooting from 16% to 56%.
- Intervention effect Five weeks of nutrient medium with 6% sucrose further improved rooting, especially for a difficult clone.
- Observation The shoots formed vigorous plantlets that acclimatised to full sunlight within 4–6 weeks.
- Observation Plantlet survival ranged from 90 to 100%.
