Beer: CO2 increase in the atmosphere augments tolerance of barley to salinity

From PhysOrg:

In future, climate change will bring an increase in salty surfaces on the Earth and in the concentration of CO₂ in the atmosphere. However, this higher CO₂ has some positive effects on the physiology of barley plants and increases its tolerance to salinity. This is the conclusion of the PhD thesis of Ms Usue Pérez-López, defended at the University of the Basque Country (UPV/EHU).

Barley is one of the most important crops in the world. In fact 56 million hectares are under barley crops, making it the fourth most grown cereal worldwide. It is widespread over all the Continents, given that it adapts very well in different habitats. As with other plants, the correct development of barley depends on a suitable balance between the availability of water, nutrients and CO₂. Nevertheless, it is predicted that there will be an increase in salinity in the soil in future, causing various imbalances which will result in a reduction in the growth of barley....MORE
