Annotation

Changes in the antioxidant status of etiolated seedlings of winter (cultivars Mironovskaya 808, Kazanskaya 285) and spring (cultivar Kerba) wheat Triticum aestivum L depending on their capacity to low-temperature hardening (4-5oC, 3 d) were investigated. The degrees of constitutive and cold-inducible thermoresistance were determined by electrolyte leakage after testing freezing (-15oC, 2 h). Phasic and cultivar-specific character of the dynamics of investigated parameters and increase of hydrogen peroxide contents by 3 d of hypothermia, more pronounced (almost in 2 times) in spring wheat, were ascertained. According to our data, the difference between frost-and winter-resistance of field plants of used winter cultivars ran up to 20%. The obtained results are evidence of the genetic determined abilities of winter wheat etiolated seedlings to increase their thermoresistance during cold acclimation according to the different frost-resistance degrees of field plants.
