  The Protective Effect of Zingeron Against Salt Stress in Barley

  Bulut, Hüseyin

  Among the abiotic stresses, drought is the most restrictive factor in the production of agricultural products. And the salinity comes after drought as a second major factor. It is foreseen that this problem will get worse as an increase in the salinity of the soil is predicted due to climatic changes. Environmental stress factors cause a decrease in the defense system activities of organisms and an increase in the reactive oxygen species (ROS). The increasing ROSs cause DNA and RNA damage. In this study, it is aimed to determine the protective effect of zingeron in Hordeum vulgare L. seeds exposed to salt stress in these 5 different doses (50, 100, 150, 200 ve 250 mM). IRAP (Inter Retrotransposon Amplified Polymorphism) technique has been used to determine the values of GTS (Genomic Template Stability) and polymorphisms constituted of the retrotransposon mobility triggered by the salinity stress. According to the results of IRAP analysis, polymorphism values of barley samples exposed to salt stress vary between 40.74% and 18.51% and the average is 28.88%. GTS value varies between 81.49% and 59.26% and its average is 71.12%. In addition to salt stress, the value of polymorphism decreased in the range of 14.81% to 33.33% in barley samples where zingeron was applied, and the average decreased to 24.43%. GTS value increased from 66.67% to 85.19%, and its average increased to 75.57%. It was determined from the study results that zingeron alleviates salt stress and reduces retrotansposon mobility.
