Abstract
Aim. To define the changes of indexes of sowing quality of seed of corn during growing in the conditions of different level of muddiness of ecotopes by heavy metals. Methods. Field, laboratory, matematyko- ctatyctychhyj. In researches variants are foreseen with the artificially created backgrounds of lead, cadmium, zinc. Results. Energy of germination, likeness, force of initial height of seed of corn, is certain, that is got in ecotopes, muddy zinc, lead, cadmium. Quality of soil did not have a reliable influence on likeness and energy of germination, but force of plantlets of seed went down with the increase of concentration of heavy metals in soil. Conclusions. In the conditions of Right-bank Forest-steppe on territories with content in the arable layer of lead - 50-1000 mr/kr, to zinc - 25-500, to the cadmium - 1-20 mr/kr grey forest soil it is not recommended to grow corn for seminal aims. The indexes of force of height of sowing material went down after the amount of plants on 14-28%, and by mass of plantlets - on 29-46% comparatively with unpolluted a background.

Keywords: corn, heavy metals, likeness of seed, force of height, energy of germination.
