Abstract:
Abiotic stresses like water stress, temperature stress, mineral stress, oxidation stress are major limiting factors in plant growth and development and will soon become even more severe as desertification covers more and more of the world’s area. Herbaceous crops are generally sensitive to environmental extremes, and thus high temperatures and limited soil moisture are the major causes of low yields in the tropics and will be further magnified by climate change. The response of plants to environmental stresses depends on the plant developmental stage and the length and severity of the stress. Stress physiology studies identify mechanisms of stress tolerance and provide an approach, method, and traits for screening stress-resistant genotypes.
