How does Indole-3-butyric acid (IBA) affect root induction in in vitro propagated sweet potato shoots?

Label:chem

Topic
Root induction is a critical step in micropropagation protocols. The study investigates the effect of different concentrations of Indole-3-butyric acid (IBA) on root induction in sweet potato shoots, as IBA is known to promote root development in various plant species.
Answer
The study found that 100% root induction was achieved on half-strength MS medium supplemented with 0.49 mM IBA. This concentration resulted in the highest number of roots per explant (9.75 ± 1.21) and numerous vigorous secondary roots. This indicates that IBA at 0.49 mM is highly effective for root induction in sweet potato shoots, facilitating successful micropropagation and acclimatization of the plants.
