Развитие окислительного стресса у табака, вызванное ионами меди

Abstract

The reaction of tobacco leafs to copper ions in 0, 0.2, 1.0, 10.0 mM concentration were studied. All concentrations induced oxidative stress — decline in protein concentration, increase in lipid peroxidation level. The highest level of stress was induced by 10.0 mM copper concentration after 12 hours. Chlorophyll level was not informative as the early stress marker, because chlorophyll concentration was approximately the same in all experi­mental condition.
