Abstract : Preplanting application of phenolic compounds, p-hydroxybenzoic acid, p-coumaric acid or ferulic acid, generally promoted auxin-induced rooting of mango cuttings (difficult to root). Ethephon also stimulated rooting in the presence of auxins. Synergism was more pronounced in the presence of IBA than of IAA. The root-promoting effects of auxins and non-auxin chemicals were partly related to the utilization of carbohydrate fractions from the region of root formation. The utilization of reserve polysaccharides assumed greater importance only during the root development phase.
