Decreasing substrate osmotic potential produced in seedlings of Vigna catjang ENDL. (cv. Pusa Barsati) proportional decrease in relative water content and leaf water potential, increase in respiration rate, proline content, H2O2 content, and the activities of indole acetic acid oxidase, ascorbic acid oxidase, peroxidase and glycolate oxidase but decrease in catalase activity and glycolate content. Pretreatment with reducing agents like L-cysteine or reduced glutathione (10-3 M) caused lower decrease in the relative water content, leaf water potential and glycolate content and reduced the rise of respiraion rate, proline content and H2O2 content and also the activities of aforementioned oxidative enzymes, except catalase activity which was increased. Such treatments also maintained the chlorophyll and protein levels and decreased the tissue permeability. It was concluded that the treatment of Vigna seedlings with reducing agents reduced the deteriorative changes and oxidative processes which are characteristic of water stressed tissue. |
