Book Description
The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.

Book Description
The symposium on high salinity tolerant plants, held at the University of Al Ain in December 1990, dealt primarily with plants tolerating salinity levels exceeding that of ocean water and which at the same time are promising for utilization in agriculture or forestry. The papers of the proceedings of this symposium have been published in two volumes. This volume (1) deals with mangroves and inland high salinity tolerant plants and ecosystems and is divided into the following categories: 1. Vegetation analyses and descriptions of mangroves; 2. Ecosystem analyses; 3. Physiological analyses; 4. Utilization of mangroves and saltmarsh plants; 5. Soil and water analyses. Volume 2 deals with the improvement of salinity tolerance for traditional crops under marginal soils and irrigation water and is published in `Tasks for Vegetation Science' series (TAVS) Vol. 28.

Book Description
Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income. Presenting recent research findings on salt stress, water stress and stress-adapted plants, this book offers insights into new strategies for increasing the efficiency of crops under stressful environments. The strategies are based on conventional breeding and advanced molecular techniques used by plant physiologists, and are discussed using specific case studies to illustrate their potential. The book emphasizes the effects of environmental factors on specific stages of plant development, and discusses the role of plant growth regulators, nutrients, osmoprotectants and antioxidants in counteracting their adverse affects. Synthesising updated information on mechansisms of stress tolerance at cell, tissue and whole-plant level, this book provides a useful reference text for post graduate students and researchers involved in the fields of stress physiology and plant physiology in general, with additional readership amongst researchers in horticulture, agronomy, crop science, conservation, environmental management and ecological restoration.

Book Description
Halophytes are those plant species that can tolerate high salt concentrations. There are diversified species of halophytes suited for growth in various saline regions around the world, e.g. coastal saline soil, soils of mangrove forests, wetlands, marshlands, lands of arid and semiarid regions, and agricultural fields. These plants can be grown in soil and water containing high salt concentrations and unsuitable for conventional crops, and can be good sources of food, fuel, fodder, fiber, essential oils, and medicine. Moreover, halophytes can be exploited as significant and major plant species for the desalination and restoration of saline soils, as well as phytoremediation. This book highlights recent advances in exploring the unique features of halophytes and their potential uses in our changing environment.

Book Description
This book contains current knowledge and the most recent developments in the field of halophyte biology, ecology, and potential uses. Halophytes are characterised as plants that can survive and complete their life cycle in highly saline environments. This book explores the adaptive mechanisms and special features of halophytes that allow them to grow in environments that are unsuitable for conventional crops and considers their role as a source of food, fuel, fodder, fibre, essential oils, and medicines. Halophytes and Climate Change includes coverage of: - Special morphological, anatomical, and physiological features of halophytes - Ion accumulation patterns and homeostasis in halophytes - Potential use of halophytes in the remediation of saline soil - Growth and physiological response and tolerance to toxicity and drought - Mangrove ecology, physiology, and adaptation Written by a team of international authors and presented in full colour, this book is an essential resource for researchers in the fields of plant physiology, ecology, soil science, environmental science, botany, and agriculture.

Book Description
A major, worldwide threat to agricultural productivity is undoubtedly due to environments with stressful factors, including drought, salinity, and extreme temperatures. Based on contributions presented at the International Conference on Biosaline Agriculture and High Salinity Tolerance, held in Gammarth, Tunisia, November 2006, this book reviews the current state of knowledge in biosaline agriculture and high salinity tolerance in plants.

Book Description
[Truncated abstract] Growth and physiological mechanisms of salt tolerance in three halophytic turfgrasses (Distichlis spicata, Sporobolus virginicus and Paspalum vaginatum) and a non-halophyte (Pennisetum clandestinum) were studied. Field experiments were conducted at a site in Western Australia with plots irrigated either with saline groundwater (13.5 dS m-1) or potable water, to assess changes in soil salinity and responses of the turfgrass species. Glasshouse experiments further characterised physiological responses to high levels of salinity. Key questions addressed by this study regarding the use of saline irrigation water were: (i) Will build up of salts in the soil have adverse effects on growth and quality of turfgrass, and what irrigation volumes are required to best manage salt accumulation? (ii) Will halophytic grasses prevent large increases in Na+ and Cl- concentrations in leaf tissues and thus retain high leaf colour, as compared to the non-halophyte, as a major criterion for salinity tolerance? (iii) Will turfgrass water use by the halophytes be maintained under saline irrigation, whereas declines in water use are expected for the non-halophyte if suffering from salinity stress? (iv) After salts are leached out of the root-zone by autumn/winter rains, how well can the halophytic and non-halophytic turfgrasses recover? In a field experiment, saline water ECw of 13.5 dS m-1 and potable water were used to irrigate replicated plots of the four species. Changes in soil salinity were evaluated; ECsoil solution was ~6.5 dS m-1 prior to saline irrigation and increased gradually to ~ 40 dS m-1 by mid-summer, and growth of the non-halophyte was severely reduced. By contrast, growth of two of the halophytes was not impeded (S. virginicus and D. spicata). Colour remained unchanged for the three halophytes, but it declined in P. clandestinum. In addition, the species differed in vigour; P. vaginatum was the most vigorous of the studied species. Toxic ions (Na+ and Cl-) increased in concentration in the leaf tissues of the four species when irrigated with saline water, however, mechanisms of ion exclusion (or excretion) enabled the halophytes to maintain lower Na+ and Cl, and retain higher K+:Na+ ratio than the non-halophyte. S. virginicus and D. spicata contained ~50% less Na+ and Cl- than P. clandestinum...
