The effect of temperature in interaction with other factors of climatic change on selected physiological parameters and yield of C3 and C4 crops
Jiras, Tomáš ; Albrechtová, Jana (advisor) ; Mašková, Petra (referee)
The current climate change mainly involves global warming of the Earth, and anthropogenic activity is predominantly identified as the dominant cause. As a result of the ongoing climate change, there are ever-expanding areas with rainfall deficits, extreme weather patterns including heat waves, etc. Plants must be acclimated or adapted to worsening environmental conditions in the short term as a result of the climate change. Stress load significantly changes plant physiological parameters, even lethally. Plants respond to stress by acclimation responses and adaptations induced by changes in gene expressions on metabolic, physiological or structural levels, by phenotype modification, and other changes. The threat also affects agricultural plant production, which is obliged to ensure food security of the ever-increasing human population. The climate change is expected to reduce crop yields. The aim of this Thesis is to summarize knowledge about changes in crop physiology and agricultural production due to stress factors of the climate change, especially temperature, with emphasis on differences between C3 and C4 plants. Most of the work deals with C3 cereals: wheat, barley, rice and C4: corn, sorghum. Different responses of these crops are discussed, such as change in phenology, water use, CO2...
