Bioindication of soils at high level of impurity in the conditions of modeling experience

The lowered ability of soils and technogenic superficial formations of Perm to performance of ecological functions is connected with alkalinity, salinity and pollution by heavy metals. In adverse conditions there is an accumulation of active forms of oxygen (АFО) by plants therefore the oxidizing stress develops. Accumulation of AFO leads to various functional infringements. In this connection the system antioxidant protection has special value in the course of adaptation of plants to adverse factors of environment
