Plant resistance to abiotic stresses

Abstract

Environmental phenomena often create stressful situations for plants, significantly impacting their metabolism. This can lead to development problems and, thus, drops in production and final quality. Depending on the plant, biotic and abiotic stresses can reduce average plant productivity by up to 90%. Abiotic stresses, in particular, are linked to environmental factors that are indispensable for development and production but can become limiting under certain conditions. For example, water is essential for plant growth in water stress, but deficiency can cause severe damage, as can excess, leading to water stagnation and root asphyxia, compromising final yield. All environmental factors, under extreme conditions, can be dangerous for crops, so it is necessary to know all the physiological aspects to which plants are subjected, which come into play following stress, to control it better.
