rooting on Dracaena
Quick answer
If your Dracaena has rooting, the most likely cause is: NAA (1-naphthaleneacetic acid) at 0.3 ppm promotes root initiation in Dracaena by stimulating ethylene production and cell elongation in the basal region of shoots, achieving 3.13 roots per plantlet with 5.93 cm average length
Start here:
- 1. 1. Select healthy shoots (2-3 cm length) from multiplication stage for rooting
- 2. 2. Transfer to MS medium with NAA at 0.3 ppm as sole auxin

How to reverse rooting on Dracaena
- 1
1. Select healthy shoots (2-3 cm length) from multiplication stage for rooting
- 2
2. Transfer to MS medium with NAA at 0.3 ppm as sole auxin
- 3
3. Alternatively test IBA at 0.1, 0.2, 0.3 ppm concentrations for comparison
- 4
4. Incubate at 25±2°C, 70% RH, 16h photoperiod for 45 days
- 5
5. Record root number per plantlet and average root length at harvest
- 6
6. Move rooted plantlets to acclimatization stage: peat moss only, 100% survival
Keep rooting off this Dracaena
Avoid IBA at 0.1 ppm for Dracaena rooting as it produces lowest root numbers; NAA outperforms IBA in this genus
