Abstract: (145 Views)
Evaluation of the tolerance of different wheat cultivars to environmental stresses, especially salinity stress, and its effect on wheat in different stages of growth is an important factor in choosing them for cultivation under these stress conditions. Therefore, knowing the mechanisms of tolerance to salt stress in wheat will help to choose suitable cultivars for cultivation in areas that are exposed to this stress. The present study was evaluated with the aim of investigating the effect of salinity stress on different varieties of wheat in order to identify the mechanisms involved in the transmission of the defense message of this plant from the biochemical and molecular aspects. The experiment was conducted in a factorial manner based on a completely randomized design, with three replications in the greenhouse of the Faculty of Agriculture of the University of Mohaghegh Ardabili. The investigated factors include salinity stress at three levels (zero, 100 and 150 mM sodium chloride (NaCl)), six wheat cultivars (Quds, Azadi, Arg, Tajen, Flat and Bam) and sampling time (before applying stress was 7, 14 and 21 days after application of salt stress). From the two-leaf stage onwards, the samples of the salinity stress level for the first three days were stressed with salt solution, every day with a concentration of 50 mM, so that the plants would not be shocked by sudden salinity stress. After 3 days, the plants were exposed to stress with concentrations of 100 and 150 mM sodium salt, and normal water was used for the control treatment. The results showed that the amount of proline, total protein, lysine and methionine increased with the increase in salinity stress. Also, under salinity stress, protein accumulation was higher in Bam, Arg and Plat cultivars than Tajen, Quds and Azadi cultivars. As a result, the numbers deal with the toxicity caused by salinity by using different defense mechanisms. In general, according to the results of this research, it can be concluded that salinity changed the studied biochemical traits, and among the cultivars studied, the Arg cultivar showed more tolerance to salinity stress. Also, in general, the accumulation of proteins in Bam, Arg and Plat varieties was higher than Tajn, Quds and Azadi varieties.
