Abstract:

Sugar beet is one of the strategic products of our country with high efficiency in terms of food. On the other hand, salinity is one of the most important limiting factors of economic use of grounds for cultivation of agricultural plants and one of the most significant research areas of researchers of the new plant science is the study of biological changes of the plant in stress conditions and the observation of physiologic and morphological changes. Thus, studying and choosing of traits that could be used instead of performance traits in choosing resistant or stress-sensitive cultivars, will be much easier and less costly. Thus, for this purpose, an experiment was carried out so as to evaluate the 20 genotypes of sugar beet in salinity stress conditions as a factorial experiment and a completely randomized block design in three replications in the greenhouse environment. The results showed that in salinity stress conditions except for the stem dry weight, a significant difference was observed in other traits. Studies showed that there was a significant difference at the 1% level between evaluated genotypes in terms of all evaluated traits. Salinity stress × the genotype interaction was significant only in the traits of per leaf area and stem dry weight. Salinity stress caused a 21.65% reduction in plant height, 20.65% in leaf length, 19.54% in leaf breadth, and 23.37% in leaf area.
