Rooting hormone
 

I have a rooting hormone called sim root by plant prod and it says its 0.1 % IBA and i was wondering if i could use this in place of KLN. I have a Beallara that lost a lot of root and i want to put it into water culture( not s/h) and i was wondering if i could add a bit of this to the water instead of KLN (cuz i don't have any) instead?

IBA, or indole-3-butyric acid, is a plant hormone that directly affects root growth. It is an ingredient found in K-L-N and would be an appropriate substitute, but it may not work as well.

I found some old KLN literature on the Internet and the amount of IBA in KLN was .0001%. It is so low that they are not required to list it as an ingredient.

It makes me wonder if the label on your package is really .1%.

The biggest problem is that IBA is usually a powder that does not dissolve well.

Go ahead and use it. I prefer the liquid form of Gibberelic acid (Essential brand made from seaweed), which is about the same in rooting capability and much easier to use being a liquid.

Root growth on a Brlla will be very slow as expect it. Oncidium Intergeneric seem to grow very well with very little roots.

K-L-N contains about 0.1% each NAA and IBA.

If Sim Root is a liquid, go ahead and use it. If not, don't even bother.

I've used this, didn't care for it - its just rotted out my stem cuttings :Tdown:.

About hormones. Is AIA (indol acetic acid) as efficient than IBA (indol butyric acid).

If I am not mistaken, IAA is labile in solution. I don't think it is used commercially.

You are right, it is what I also read in a In-Vitro culture book. Can we imagine that it can be used mixed with some talc? Here in Belgium a mix NAA (naphtyl acetic acid) / talc is sold as rooting hormone for cuttings.

I don't think talc would make any difference. It is added to powdered forms of auxins to be applied dry to cuttings, but unless there is a huge gap in my knowledge, it wouldn't do anything to stabilize the IAA compound.
