Abstract The effect of Tiron (disodium 1,2-dihydroxybenzene-3,5-disulfonate) on the growth, morphology and alkaloid content of adventitious roots in Atropa belladonna was investigated. High concentrations of Tiron had an inhibitory effect on growth of the root. The appearance of cultured roots was significantly changed from rough roots accompanied with callus-like tissue in control cultures to fine roots without callus formation. Alkaloid content was drastically increased by the addition of 1 mM Tiron to the medium. The influence of NAA, which has an inhibitory effect on alkaloid production, was partially restored by Tiron treatment, indicating that this radical scavenger may affect the production of alkaloids through modulation of the mode of action of auxin. Glutathione content of the root was not influenced by Tiron.
