Re: Rooting woody cuttings
Dear Sheryl, dear Cindy,
IBA is Indole-Butryric-Acid, an auxin, one kind of plant hormone, used in tissue
culture for rooting and callus induction and horticulture in rooting powders for
rooting cuttings. You can probably obtain commercial rooting powsers with IBA,
others contain NAA, Naphtalene-Acetic-Acid, another auxin. The chemical IBA can
be probably obtained, for instance, at www.kitchenculturekid.com, the sit of
Carol M. Stiff who supplies stuff for home tissue culture.
Hope that helps,
Bernhard.
