Evaluating the Impact of Salinity on Physiological, Chemical, and Biochemical Traits in Wheat (Triticum aestivum L.) Genotypes

The effect of salinity on growth, yield and physiological parameters of five bread wheat genotypes was studied.The experiment set in a controlled environment to observe the umma'n response in wheat plants using salinity treatments of 0, 10 and 15 dS/m.The increase in salt concentration led to a decrease in the length and dry weight of plants and spikes.Under control conditions, SARC-8 had the maximum shoot length whereas SARC-5 had the maximum root length.All genotypes showed significantly less shoot and root growth at higher salinity (EC = 15 dS/m) and SARC-8 showed the highest resilience with respect to root dry weight.Grain yield also drastically decreased under salt stress.Unaj-2017 produced maximum grain yield under moderate salinity (EC = 10 dS/m).The study results indicate that salinity stress hinders growth parameters and yield, but these variables differ across genotypes.It is essential to grow salt-tolerant varieties of wheat in areas with salinity problems.
