Use of gibberelic acid

carlos_asut(8b)June 25, 2002

Does anyone of you guys have any experience using gibberelic acid (ProGibb) to control bolting?

Specifically I want to control bolting in basil and in spiny coriander.

Thanks

I have heard of use of gibberelic acid to INITIATE (cause) bolting, mostly in artichoke production and in the production of long stem flowers for cutting. Search for +gibberellic +bolting.

I have read of using it prior to Camellia Blooming in the fall...

I haven't heard about using gibb to stop flowering or shoot extension. There are other chemicals on the markets for non-edible plants, materials meant to dwarf plants.

Coriander (cilantro) readily goes to flowering and seeding; however, in the US there are cultivars with names such as "Slo-bolt" (Johnny's Sel. Seeds) reputed to be slower to bolt.

I grow nine kinds of basil. All will start flowering early if stressed by climatic or watering extremes. I try to start them off well and pinch terminals starting when the plants are small so as to increase branching. I find the flavor of annual basils (Genovese, Neopolitino, Monstuoso, the various reds, and the licorice to be best at flowering. The perennials tend to be much stronger-flavored and seem to want to drop leaves as they go into flowering. But this last observation is preliminary. I am in my second year of side-by-side trials.

The American Camellia Society sells gib kits and has information about using gib for earlier, larger camellia blooms.

The best way to prevent bolting is to pinch back often.-Sandy

The commercial growth regulator, Arest, is a gibberellin antagonist, but it is not for use on food crops.

You might want to try Googles new beta product http://scholar.google.com/ and search for +gibberellic +bolting

I think gibberellic acid is more likely to cause bolting rather than stop or slow it down. Kinetin might help as it encourages side growth as opposed to strong central growth . I would try 80ppm.
