Abstract

Salinity, or salt stress, disrupts the absorption of nutrients, reduces water intake and photosynthetic activity, thus decreasing the yield in plants with loss of biomass. In this ongoing study, widely grown varieties along with advanced selection genotypes, which have promising feature, are being used. In the first year of this study, which is planned to last two years, genotype and varieties’ tolerance levels in salinity stress will be determined and in the next year, commercial biostimulant and abscisic acid will be applied to selected plants (sensitive, semi-tolerant and tolerant) in order to provide salt tolerance. Our preliminary results indicate that advanced selection genotypes have better salinity tolerant in comparison with common varieties. Thus, it is thought that the study will provide data for both breeding and molecular research, and recommend the use of commercial products for large-scale producers.
