New slow release formulations (SRF) of 1-naphthylacetic acid (NAA) were synthesised and the expression of their auxin-like activity was examined by studying their effect in inducing callus formation and organogenesis in leaf segments of tobacco. The SRF were water-soluble copolymers of acrylamide containing side-linkages with NAA, the latter being released during hydrolysis (cleavage of chemical bond). Callus formation was assessed by fresh weight measurements and that of organogenesis, morphologically A shift of the effective (optimal) concentrations to higher values was noticed when increasing the polymer molecular weight or the content of NAA in the polymeric formulations. The relationship between polymer structure, hydrolysis rate and the biological effect was obvious.
