Abstract
Abstract The effects of aluminium (Al)-induced alterations on elongating radicles of Cicer arietinum L. were studied in relation to growth and biochemical markers of oxidative stress. Elongating radicles (c. 1 mm) were treated with 0–3 mM aluminium chloride (pH 4.5) for seven days at room temperature (26 ± 2°C). The results indicated that exposure to Al significantly inhibited radicle growth. This growth inhibition was accompanied by excessively high levels of reactive oxygen species (ROS) production. The levels of ROS were significantly positively correlated with Al concentration. Levels of lipid and protein oxidation products increased significantly with an increase in Al concentration, and were significantly positively correlated with ROS levels. On the other hand, Al stress significantly decreased the activities of selected enzymatic antioxidants. Collectively, the results suggest that Al rhizotoxicity in C. arietinum is partially mediated by oxidative stress brought about by excessive ROS production and reduced antioxidant scavenging activity.
