Bioindication of territories with elevated radioecological pressure

It was confirmed that in plant genome of different systematic groups, growing in Radio-ecological reservation, the changes, dealing with partly not repaired DNA damages and redistribution of its parts, bounded with proteins, changes of cells and nuclei size, changes of pigment system functioning and assimilation apparatus are taking place. Express-method of PDN definition in the cell nuclei was elaborated. Radiation is differently influences on morphophysiological and biochemical parameters of plants of different systematic groups and ages, which can be the indicator of environment influence.
