Hi,
It really depends on what you want to do. IAA is more easily degraded and if you are looking for inhibition might be better to use a more stable one. I have used NAA for the experiments with auxin I have done.
Best wishes
It also depends on if you are studying auxin transport/uptake. Some auxin analogs can cross the membrane without reliance on a transport protein. Cost and stability are of course factors too.
Dear Dr. Svetlana Boycheva Woltering & Dr. Amy Klocko
I appreciate your guidance.
IBA is the most abundant natural auxin after IAA. In many species, it has been found that the IBA gets converted into IAA. Among all the auxins, IBA is the most used hormone due to its high rooting capacity. However, it is not degraded into IAA during long-distance transport.
Both auxins having their importance. IBA is rooting hormone but at low it is potential powerful auxin in plant tissue culture. The aucin IAA has limited applications in organogenesis especially conifers but not playing any role in rooting.
Dear Dr. Baljit Gill & Desta Lamore Erebo
I appreciate your guidance.
The choice between Indole-3-butyric acid (IBA) and Indole-3-acetic acid (IAA) depends on the specific goals of your experiment. IBA is often used for root initiation in plants, while IAA is a natural auxin involved in various growth processes. Both can be valuable depending on your experiment's objectives regarding plant growth, rooting, or hormonal responses.
