Strategy for suppressing redox stress during tomato (Solanum lycopersicum L.) seed germination

Abstract A series of pyrimidinol-based compounds have been synthesized and evaluated for their ability to increase seedling biomass during seedling development. The compounds have the ability to reduce oxidative stress catalytically as natural phenolic antioxidants such as α-tocopherol do,...
