Changes in vitamin E content and activity as a response to abiotic stress in spring barley varieties
The effects of three different soil moisture regimes (drought, late drought and wetness) on the defense response of barley genotypes assessed using vitamin E isomers were studied in 2009 and 2010. Vitamin E isomers were determined by HPLC with fluorescent detection. Genotypes with contrasting maltin...

Summary: | The effects of three different soil moisture regimes (drought, late drought and wetness) on the defense response of barley genotypes assessed using vitamin E isomers were studied in 2009 and 2010. Vitamin E isomers were determined by HPLC with fluorescent detection. Genotypes with contrasting malting quality (hulled Kompakt, Krona, Wabet and hulless Wanubet, KM 1057) were included in the study. The lowest average concentration of vitamin E isomers (8.38 mg/kg) was found in the late drought regime. The highest vitamin E activity in the drought and late drought regimes was found in the genotypes Wabet and KM 1057 (9.43 to 18.08 mg/kg), which may be due to their stronger defense mechanism to drought stress. |
