Buckwheat could become an alternative to wheat 

Drought, heat and high levels of CO 2 have raised concerns about adequate wheat production. Spanish scientists have proven that buckwheat is much better able to withstand such extreme conditions, World of NAN reports with the reference to Environmental and Experimental Botany.

In the future, cereal crops will have to endure longer and more severe periods of drought, as well as high CO 2 levels and temperatures. These conditions are detrimental to traditional cereals. And in the future they are planned to replace them with cereals: buckwheat, sorghum, spelt and others.

In an experiment, the researchers proved that buckwheat is the most resistant to the coming changes. Scientists grew plants of two species in a growth chamber and controlled conditions of temperature, CO2 and drought.

"By analyzing various plant physiological parameters, it was found that buckwheat has the potential to become an alternative to wheat as a cereal. At high CO2 levels and temperatures, even if there is no drought, some wheat parameters are already deteriorating: wheat growth is restricted while buckwheat is not. Also the photosynthesis level of buckwheat increases while that of wheat decreases. In general, buckwheat was found to respond better to climate stresses compared to wheat," scientist Javier Simon said.
