Realization of productive potential in winter wheat under drought

Keywords: Triticum aestivum L., shoot, grain, productivity, drought


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