| Abstract | The World Bank estimates that global food production must increase by 70% to feed 9.7 billion people by the year 2050. Soil resources are shrinking due to various types of soil degradations, including soil salinity, aridity, waterlogging, erosion, and pollution. There are number of approaches which can be employed for sustainable utilization of degraded soil resources. However, selection and development of tolerant germplasm against abiotic stresses is a promising strategy to bring these lands back into cultivation. The complex nature and simultaneous occurrence of more than one abiotic stress demands on the development of plants tolerant to multiple stresses. However, main limitations in the development of stress-tolerant germplasm are attributed to its quantitative nature, impacts of environmental conditions, and non-availability of adequate selection criteria and individual efforts to understand the genetic, physiological, morphological basis of abiotic stress tolerance in plants. The physiological traits are vital in evaluating the plant genotypes against abiotic stresses. The germplasm may be more tolerant if selection is made directly on the relevant physiological mechanism. Genetic variation exists for that mechanism in plants and target traits are heritable. The physiological indicators can be successfully used for rapid screening of large germplasm against abiotic stresses without requiring expensive sophisticated equipment. The study of stress physiology is important not only for plant physiologists, but also for plant breeders and soil scientists, who are struggling to develop stress-tolerant varieties of different crops. This chapter aims to explain the role of physiological determinants to be used as selection criteria against major abiotic stresses, including salinity, drought, and waterlogging. A clearer understanding of the physiological processes under stressful environments will help address the development of plants better able to withstand abiotic stresses with little yield reductions. |
