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...

44 Effects of polyploidy in allohexaploid wheat (Triticum aestivum L.) have primarily been ascribed 45 to increases in coding sequence variation and potential to acquire new gene functions through 46 mutation of redundant loci. However, regulatory variation that arises through new promoter and 47 transcription factor combinations or epigenetic events may also contribute to the effects of 48 pol...

The relationship between root morphological and physiological responses to variable P supply in different plant species is poorly understood. We compared root morphological and physiological responses to P supply in seven crop species (Zea mays, Triticum aestivum, Brassica napus, Lupinus albus, Glycine max, Vicia faba, Cicer arietinum) treated with or without 100 mg P kg-1 in two soils (acidic ...
