Abstract

The title of this research is "The Effect of Salt Stress on Biochemicals of Chili at Seedling level of Chili (Capsicum annuum L.)”. The plant was hydroponically grown in half-strength NaCl solution for 20 days followed by treatments with 0, 50, 100 and 200 mM NaCl for 18 days. Growth parameters of 45-day- old plants were recorded. The plants were harvested and analyzed for the amount of chlorophyll, proline, catalase (CAT) and peroxidase (POD). The low (50 mM NaCl) level of salinity treatment had no deleterious effects on vegetative growth parameters, at higher concentration of NaCl (100 and 200 mm), growth parameters were drastically reduced. Salinity treatments caused a reduction in chlorophyll content, accumulation of proline and enhancement of CAT activity in shoot and root.
