Morpho-physiological and biochemical attributes of Chili Capsicum annum L. genotypes grown under varying salinity levels

Popis výsledku v původním jazyce

Climate change is causing soil salinization, resulting in huge crop losses throughout the world. Multiple physiological and biochemical pathways determine the ability of plants to tolerate salt stress. Chili Capsicum annum L. is a saltsusceptible crop, therefore, its growth and yield is negatively impacted by salinity. Irreversible damage at cell level and photo inhibition due to high production of reactive oxygen species ROS and less CO2 availability caused by water stress is directly linked with salinity. A pot experiment was conducted to determine the impact of five NaCl salinity levels, i.e., 0,1,5, 3,0, 5,0 and 7,0 dS m1 on growth, biochemical attributes and yield of two chili genotypes Plahi and A120. Salinity stress significantly reduced fresh and dry weight, relative water contents, water use efficiency, leaf osmotic potential, glycine betaine GB contents, photosynthetic rate A, transpiration rate E, stomatal conductance Ci, and chlorophyll contents of tested genotypes. Salinity stress significantly enhanced malondialdehyde MDA contents and activities of the enzymatic antioxidants such as superoxide dismutase SOD, catalase CAT and peroxidase POD. In addition, increasing salinity levels significantly reduced the tissue phosphorus and potassium concentrations, while enhanced the tissue sodium and chloride concentrations. Genotype Plahi had better growth and biochemical attributes compared to A120. Therefore, Plahi is recommended for saline areas to improve chili production.
