Abstract

Salinity is an important source of abiotic stress, limiting crop performance in most arid and semi-arid areas of the world. This research was conducted to determine the effects of salinity on physiological parameters of durum wheat (Triticum durum Desf.) genotypes. The research was conducted in the tissue culture laboratory at the Agriculture Faculty of Dicle University. The study consisted of one durum wheat commercial cultivar, five local cultivars and four advanced genotypes. There were three replications in a split-plot experimental design. Genotypes were germinated in four NaCl concentrations (0, 50, 100, 150 mM) in plastic boxes. There were statistically assured significant differences among the genotypes for all salt concentrations and all observed parameters (coleoptile length, seedling length, root length, seedling fresh weight, root fresh weight, seedling dry weight, root dry weight, germination rate and seedling vigor). There was significant decrease in all examined parameters depending on the increase of salt concentration. The ‘Sorgul’ genotype was most tolerant to salinity, in terms of root length and root dry weight, whereas ‘Altintoprak 98’ was most tolerant as measured by the impact of salinity on coleoptile length, seedling fresh weight, germination rate and seedling vigour. The ‘Beyaziye’ genotype was the most sensitive to salinity-induced stress. The results from this study demonstrated differences among durum wheat genotypes for seedling parameters measured in the presence of salinity stress.
