Investigation of some Biochemical Traits of Tolerant and Sensitive Wheat Cultivars (Triticum Bioticum) under Salinity Stress

Salinity is one of the most important abiotic environmental stresses and is one of the most important factors in reducing the growth and yield of crops including wheat. Wheat is one of the most important crops in Iran and Wheat peloid levels are an important source of excellent genes, and it is highly desirable to study these species for use in breeding activities. Diploid wheat has 27 different species, among them T. boeticum is the most widespread type of wild wheat being distributed in the cold semi-western regions of the country. This study was conducted in 2009 at Graduate University of Advanced Technology on two different genotypes of T. boeticum wheat, which belongs to Kurdistan and Lorestan of Iran. The seeds of these wheat were cultured in the winter of 2018 as a factorial experiment in a completely randomized design with 3 replications and statistically analyzed at two levels of salinity stress of 0 and 125 mM. The results of analysis of variance of traits including photosynthetic pigments, soluble sugars, proteins, phenols, proline, ionic leakage, relative humidity, hydrogen peroxide, root length, some antioxidant enzymes and measurement of sodium and potassium showed that There is a significant difference between the genotype levels and salinity stress levels as well as the interactions between the two treatments in terms of the studied traits.
