Abstract


In modern agriculture, salt stress is one of the major problems. The aim of the study was to investigate the effect of priming seeds of Hordeum Vulgaris with diatomite on physiological, photosynthetic and stress related aspects in laboratory conditions. The sterilized seeds were primed with three concentrations of diatomite suspensions: 1) 5g DTM/100 ml, 2)10 g DTM / 100 ml H2O, 3) 20 g DTM /100 ml. If the concentration of salt is high in the soil it will give the high osmotic potential of soil as a result and water deficit will be in plants. Moreover, a high concentration of salt could cause nutritional disequilibrium and, as a result, the production of reactive oxygen species was increased and plant growth and biomass were decreased as a stress condition was 200 mM of NaCl solution and after that their biochemical contents were determined. Diatomite may act to alleviate salt stress in the plant. This is achieved by decreasing the permeability of plasma membranes and maintenance of cell form and structure due to the increasing of antioxidative enzymes SOD and CAT. Diatomite offset the negative impacts of NaCl stress due to the increased tolerance of plants to NaCl salinity by enhancement of chlorophyll content and photosynthetic activity
