auxin rooting on Ficus
Quick answer
If your Ficus has auxin rooting, the most likely cause is: NAA (naphthaleneacetic acid) at 0.1 mg/L in MS medium with sucrose drives root initiation in Ficus carica 'Aboudy' explants, achieving 100% rooting at both 3% and 5% sucrose concentrations versus only 80% at 1% sucrose. The auxin works synergistically with sucrose to stimulate cell division in the root meristem.
Start here:
- 1. Apply 0.1 mg/L NAA as the rooting auxin in MS medium
- 2. Combine with sucrose at 30-50 g/L depending on root vs shoot priority
Why Ficus gets auxin rooting
Ficus spp.

How to reverse auxin rooting on Ficus
- 1
Apply 0.1 mg/L NAA as the rooting auxin in MS medium
- 2
Combine with sucrose at 30-50 g/L depending on root vs shoot priority
- 3
Allow 8 weeks for root development scoring at 25±1°C, 16h photoperiod
Keep auxin rooting off this Ficus
Use precise NAA concentration — exceeding 0.5 mg/L can cause basal callusing that inhibits root emergence.
