Effect of herbicide paraquat on lipid peroxidation in leaf disks of crop plants

The effect of leaf disks treatment by herbicide Paraquat has been considered for wheat, rye and maize. Lipid peroxidation in leaf disks of different crop plants was enhanced in most variants. Malone dialdehyde level varied linearly or non-linearly for different species as depended of Paraquat concentration as well as duration of leaf disks incubation in xenobiotic solutions.
