Genetic Bases of Barley Physiological Response to Stressful Conditions

Résumé fourni par la source

Genetic adaptation implies the shaping of population gene pools in response to environmental challenges due to climate and soil. Temperatures, rainfall, nutrient availability, and presence of toxic compounds have limited the diffusion of the different species. Barley is grown either in the northern countries close to the polar circle (i.e., Finland and even Iceland) or up to 4,500 m above sea level in the Himalayan mountains, as well as at the limits of the desert where the average rainfall is between 200 and 300 mm per year. Such a great diffusion, despite differences in the climatic conditions, already suggests that the barley gene pool should contain characters for wide environmental adaptability and good stress resistance.
