Abstract
Salinity is a major limiting factor for crop growth and productivity especially in arid and semi-arid areas. Therefore this study was conducted in order to compare the effect of applying Nano Silver on mitigating salinity negative effects on Bitter Vetch (Vicia ervilia L.) seeds. An experiment was conducted to evaluate the effects of silver nanoparticles (AgNPs), on the seed germination, germination percentage (GP), seedlings vigor index (VI), germination index (GI), tolerance index (TI), root and shoot length (RL and SL) of Bitter Vetch Seeds Survival under Salinity Levels. To create salinity stress, sodium chloride (NaCl) at the levels of 0 (as control), 4, 8, 12, 16 and 20 dS/m and five levels of silver nanoparticles (0, 5, 10, 15 and 20 ppm) on Bitter Vetch seed were tested. The germination percentage, shoot length, root length, seedling fresh weight and seedling dry weight traits showed significant differences among Bitter Vetch seed in treatment solutions. Overall, application of Ag nanoparticles was beneficial in improving salinity tolerance in the Bitter Vetch seedling and its application may stimulate the differences defense mechanisms of plants against salt toxicity.
