Abstract

Auxin autotrophic and heterotrophic lines of tobacco calli may differ not only in their indoleacetic acid (IAA) synthetizing abilities and sensitivities to exogenous auxins, but also in their stress tolerance. Auxin autotrophic callus tissues were generated and the growth of cultures was compared with that of the heterotrophic lines of the same tissues on MS medium containing different concentrations of NaCI. The growth remand usually higher in autotrophic calli than in heterotrophic calli with increasing NaCI concentrations. The glutathione S-transferase and peroxidase activities were higher in the autotrophic lines, but their level did not increase further with the salt treatment as much as in the heterotrophic tissue.
