Growth and productivity of wheat plants under drought in the critical phase of ontogenesis

Aim. The goal of this work was to study the effect drought in critical phase ontogenesis on growth and productivity breed winter wheat plants (Triticum aestivum L.). Methods. Wheat cultivars Darunok Podillya Podolyanka were grown under optimal nutrition well-water conditions until earing-flowering phase, after that experimental transferred regime for 8 days, water supply restored end vegetation. During experiment, leaf surface area, mass internodes ear determined. Ripened analyzed according structure yield. Results. It established caused decreasing internodes, ear, number grains plant, weight 1000 grains. Conclusions. Water deficit soil led a decrease productive due inhibition grain grains.
