Abstract

Water and soil salinity is one of the most important abiotic stresses that limit agricultural production. In this regard, this study was conducted to evaluate the effect of salinity stress on different varieties of wheat was conducted at the Agricultural Sciences and Natural Resources University of Sari in 2015. The study was conducted in two separate experiments. the effect of three levels of salinity (0, 60 and 120 mM) on 117 varieties at germination stage was investigated and Using data from the first experiment, in second experiment the effects of four salinity levels (0, 60, 120, 180 mm) on 10 varieties at reproductive stage were studied. Both factorial experiment was conducted in a completely randomized design with three replications. Using principal components analysis, 75. 56 percent of germination traits by two components and 78. 31 percent vegetative traits by three components were interpreted. The results showed that in the vegetative stage, positive correlations between shoot dry weight, shoot length and root dry weight with the total dry weight and in reproductive stage a positive correlation between the total number of seeds and seed yield were observed. Increased salinity levels, had a considerable negative effect on germination and yield. Some of the varieties that had high tolerance to salinity stress at germination stage in the growth phase weren't resistant to salinity. According to the results of this research, traits of root length, shoot length, root dry weight and shoot dry weight, are salt stress tolerance traits. Roshan zemestan, Aria and Chamran 2 varieties were identified as tolerant to salt stress and ghahte sarogh, keshe farahan and neyshabur varieties were sensitive to salinity stress.
