Realization of productive potential in winter wheat under drought

Aim. The aim of the work was to study realization productive potential bread winter wheat plants under drought (Triticum aestivum L.). Methods. Wheat cultivars Bogdana and Perlina Podyllja were grown optimal conditions until earing-flowering phase, after that experimental transferred regime for 8 days. Optimal water supply restored end vegetation. Leaf surface area, mass shoot grains measured during experiment. Ripened analyzed by yield structure. Results. It established effect deficit in critical phase ontogenesis caused decreasing leaf shoots more significantly Perlyna Podillia cultivar compared cultivar. Restoration irrigation stimulated growth grains, but did not compensate loss their number. Conclusions. Water soil delayed increasing shoots, area leaves decrease plant productivity.
