Abstract

Flooding stress has important morphological and physiological effects on crop and wild plants. FLOODING is induced by excessive irrigation or rainfall in soils with poor drainage. One of the important effects of FLOODING is the reduction of nutrient and water uptake in plants. Production of reactive oxygen species (ROS) and induction of OXIDATIVE STRESS in plant tissues are some of the other effects of FLOODING. Malondealdehyde (MDA) production is the indicator of lipid peroxidation reactions. A significant increase in MDA in plants which were flooded probably is the indication of fatty acid oxidation in the present of free radicals generated by FLOODING. In this research, seeds of Capsicum annum were sown in pots filled with vermiculate and then the pots were transferred to a controlled growth room with photoperiod of 16/8h light/dark and temperature 27/23 day/night. After three weeks, the seedlings were flooded for 3, 5 and 7 days. After sampling, antioxidant contents including ascorbic acid (ASA), carotenoids, as well as lipid peroxidation reactions and uptake of mineral elements were measured. In those plants which were flooded, ASA increased significantly. FLOODING caused a significant decrease in chlorophyll b content (p=0.05) in those plants which were flooded for 5 and 7 days. FLOODING also significantly decreased carotenoid in flooded plants when compared with controls. Flooded plants had a much higher MDA content than unflooded control plants. Potassium content of flooded plants decreased significantly, but sodium ion content was 2 to 3 times more in flooded plants in comparison with controls.
