Water-use efficiency of winter wheat under heat and drought stress

Popis výsledku v původním jazyce

Because such extreme weather events as dry spells and heat waves are expected to occur more frequentlyndue to climate change, the issue of appropriate water management for sustainable agricultural productionnis increasingly important. This study focuses on wheat, the second most widely grown cereal in the worldnand the most common cereal in European countries. The study assesses the effects of short periods (3 andn7 days) of high temperatures (26°C as a control, 32°C, 35°C, and 38°C as daily temperature maxima fromn12:00 to 14:00) and drought stress at different developmental stages (DC 31 – beginning of stem elongation,nDC 61 – flowering, and DC 75 – early grain filling) on water-use efficiency (WUE) in winter wheatncultivar Tobak. This cultivar is one of the most widespread winter wheat cultivars in Czech Republic fields.nThe analysis of WUE showed that the cv. Tobak plants were able to withstand drought stress conditionsnthrough increased WUE. In contrast, wheat plants were stressed more markedly if exposed to higher temperaturesnand drought in combination. Generally, the wheat plants were most sensitive to drought at DCn31.
