Indole-3-butyric acid to get Tricho to pup?

Recommended Posts

I was wondering if anyone has had success with using Indole-3-butyric acid to get Cactus to pup?


I bought some Indole-3-butyric acid rooting gel and sucked it up with a large syringe.


I then injected selected spots on my Trichos.


Anyone got experience?

I tend to hear of 6-benzylaminopurine being used for pupping which is quite a distinct compound (synthetic cytokinin with stimulatory effects on cell division) with a different mechanism to IBA

That said, try it and see what happens. IBA has:

- auxin-like effects such as root initiation, stem bending, and leaf epinasty

- IBA-derived auxin has strong roles in various aspects of root development, including regulation of root apical meristem size, root hair elongation, lateral root development, and formation of adventitious roots. 

- IBA-derived auxin plays distinct roles in shoot development, with particular roles in cotyledon expansion and apical hook formation.

Some studies indicate:
- IBA application promotes elongation of stems in intact pea plants "IBA could act as an important source of auxin to boost stem elongation in intact plants"

- In carrots it seems to cause longer plants "IBA significantly increased the overall plant length."

                ^ aureoles, presumably? 

I've tried a different hormone/product in the past, specifically formulated to promote pupping, and it did ... nada. (I can't remember the name, it comes in a godawful lanolin base).

Pruning the tip is the only surefire method I know of to stimulate production of new pups. Slab grafting works too, on a smaller scale. 

Interested to hear how your experiment goes.
