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

Dead Tissue

Submergence invokes a range of stressors to plants with impeded gas exchange between tissues and floodwater being the greatest challenge. Many terrestrial plants including wheat (Triticum aestivum L.), possess superhydrophobic leaf cuticles that retain a thin gas film when submerged, and the gas films enhance gas exchange with the floodwater. However, leaf hydrophobicity is lost during submergence and the gas films disappear accordingly. Here, we completely submerged wheat (with or without gas films) for up to 14 days and found that plants with gas films survived significantly longer (13 days) than plants without (10 days). Plants with gas films also had less dead tissue following a period of recovery. However, this study also revealed that reflections by gas films resulted in a higher light compensation point for underwater net photosynthesis for leaves with gas films compared with leaves without (IC = 52 vs 35 µmol photons m–2 s–1 with or without gas films, respectively). Still, already at ~5% of full sunlight the beneficial effect of gas films overcame the negative under ecologically relevant CO2 concentrations. Our study showed that dryland crops also benefit from leaf gas films during submergence and that this trait should be incorporated to improve flood tolerance of wheat.
