Ecophysiology of Vascular Halophytes

Description

Ecophysiology of Vascular Halophytes provides a useful update to existing literature describing the ecophysiological responses of vascular halophytes to environmental stresses present in saline habitats. The success of species growing in these extreme environments is related to a number of adaptations, including the timing of phenological events, phenotypic plasticity and genetic selection for specific ecophysiological responses at different stages of development. Factors discussed that influence the growth and distribution of halophytes include seed germination, salinity stress, salt stimulation, flooding, ion content, nitrogen, plant water status, growth regulators, photosynthesis, and genecology. The book also discusses the effects of both interspecific and intraspecific competition on the growth and survival of halophytes. Researchers and students of stress ecology, as well as agricultural research organizations, will find a tremendous store of information in this volume.
