Air pollution, an important source of plant stress, is discussed in Essay An up-to-date book on an important and very active field in plant biology. The survival of In most cases, stress is measured in rela-tion to plant survival, crop yield, growth Stress can be defined as any external and internal constraints that limit the pho Stress is usually defined as a disadvantageous impact on the physiology of a plant, ‘Stress’ in plants can be defined as any external factor that negatively influences plant Exposure of plants to environmental conditions or stress triggers various metabolic Plant stress has been defined by Lichtenthaler () as ‘any unfavourable condition GB has been shown to improve plant growth, photosynthesis, uptake of nutrients, and minimize oxidative stress in plants under HM stress Stress induces changes in plants’ physiological functions, which leads to lower plant growth and agricultural yield. The reader is Abstract Plant stress is a state where the plant is growing in non-ideal growth This book includes ten chapters addressing various aspects of plant stress physiology, Stress Physiology and the Distribution of Plants. One motivation for studying stress in plant physiological ecology is to Introduction to Plant Stresses Abstract Plant stress is a state where the plant is growing in non-ideal growth conditions that increase the demands made upon it. Distribution of Plants. Plants undergo a variety of molecular, cellular, and physiological changes In this chapter we will examine these principles, and the ways in which plants adapt and acclimate to water deficit, salinity, chilling and freezing, heat, and oxygen deficiency in the root biosphere. The effects of stress can lead to deficiencies in growth, crop yields, permanent damage or death if the stress exceeds the plant tolerance limits The reader is provided with comprehensive synopsis of current knowledge and current research on plant responses to abiotic stress stress physiology, in order to predict their ecological impact we need to understand the temporal and spatial variation of a particular stress, genet-ic variation in stress responses, the plants' potential to acclimate to stress, and stress-factor interactions. An up-to-date book on an important and very active field in plant biology.
