Effect of sulphite ions on the proline and polyamine content in the bean Phaseolus vulgaris

Piotr Karolewski, Nina I. Shevyakowa

Abstract


The influence of sulphite (0.0125-0.2%) on changes in the levels of free proline, protein bound proline and hydroxyproline and of free polyamines in the roots and leaves of two cultivars of beans (Phaseolus vulgaris) differing in sensitivity to these ions was investigated. It was found that both cultivars reacted similarily, the response of the seedlings of the more sensitive cultivar occuring at lower concentrations of sulphite.The observed changes in the content of imino acids and polyamines are discussed.
