Formation of hydroxyl radicals in the stems of winter wheat [Triticum aestivum] treated with freezing temperature

Levels of hydroxyl radicals were measured by the methanesulfinic acid (MSA) formed from dimethyl sulfoxide in winter wheat stems treated at a critical low temperature. The level of MSA reached more than 0.3 mu-mol per g fresh weight upon incubation at -20 degrees C. These results suggest the formati...

Description
Summary:Levels of hydroxyl radicals were measured by the methanesulfinic acid (MSA) formed from dimethyl sulfoxide in winter wheat stems treated at a critical low temperature. The level of MSA reached more than 0.3 mu-mol per g fresh weight upon incubation at -20 degrees C. These results suggest the formation of hydroxyl radicals causes the death of plants
