Salinity effect on pepper cultivars: interactive effect of sodium and zinc

Abstract : The pepper (Capsicum annuum L.) cultivation takes place primarily in warm countries where the salinity problems are often responsible for the reduction of yield at the quantity and quality level. So the adaptation of pepper to salinity conditions is very important to the improvement of the production, which implies the knowledge about the pepper behaviour when sodium chloride is present in the substrate. The study allowed the comparison of 10 inbred lines of pepper in saline conditions and the study was managed in hydroponic culture comparing the behaviour of inbreed lines with 100 mM NaCl and without NaCl in nutrient solution. When 100 mM of sodium chloride was put into the nutrient solution, the reduction of growth varied between 47 % for HDA 1109 and more than 65 % for HDA 103 compared to the reference. These different behaviours seemed to be connected to a change in sodium and zinc balance in the blade. The best growth of HDA 1109 was obtained when the plant accumulated sodium in the blade (260 mM) with a low level of zinc (24 mg/kg DM). The lowest growth of HDA 103 was linked to a low concentration of sodium (59 mM) and an accumulation of zinc in the blade (153 mg/kg DM). Inbred lines Mi 71 and Mi 96 had an intermediary behavior with a weak growth and a marked accumulation of sodium and zinc in the blade
