Анотация: Two varieties of wheat were grown on different soil types (chernozem carbonate and humus-carbonate). The influence of experimentally polluted water was investigated on the stomatal characteristics on the leaves of the two varieties, and copper, ammonium and magnesium sulfate had inhibitory effect. Wheat variety ` Yantar ` had greater dimensions of the stomata, than variety ` Sadovo ` in the same soil. Variety ` Sadovo ` grown on carbonate chernozem had larger stomata compared to the same in humus-carbonate soil
