Influence of SO2, on changes in the content of proline and hydroxyproline in the leaves of rooted Weigela cuttings

Piotr Karolewski

Abstract


The effect of sulphur dioxide on the level of free proline, protein-bound proline and hydroxyproline in the leaves of rooted cuttings from the genus Weigela differing in sensitivity to this gas was investigated. It was found that S02 causes an increase in the level of free proline and a decline in the level of bound praline and hydroxyproline. These changes are greater in the more susceptible plants than in the more tolerant ones.
