The Effect of Cytokinins on the Concentration of Hydroxyl Radicals and the Intensity of Lipid Peroxidation in Nitrogen Deficient Wheat

Senescence of plant tissues is a natural process that may be accelerated by unfavourable environmental factors, including disbalanced mineral nutrition. During plant senescence, the concentration of reactive oxygen species (ROS) increases in the cells, whereas the concentration of cytokinins decline... Ausführliche Beschreibung

520 |a Senescence of plant tissues is a natural process that may be accelerated by unfavourable environmental factors, including disbalanced mineral nutrition. During plant senescence, the concentration of reactive oxygen species (ROS) increases in the cells, whereas the concentration of cytokinins declines. Negative correlation between ROS, such as hydroxyl radical (˙OH), and concentration of cytokinins triggers the question whether the addition of cytokinins can reduce ROS production and/or its concentration. This would also reduce the level of lipid peroxidation (LP) in the senescing tissue, which is the final phase in the destruction of cell membranes by ROS. With the aim to address these questions, the effects of cytokinins (trans-zeatin, TZ, and benzyladenine, BA) on the concentration of ˙OH and LP were studied in wheat subjected to nitrogen deficiency. Foliar application of TZ reduced the concentration of ˙OH and the intensity of LP in the leaves of young wheat plants insufficiently supplied with nitrogen.
