Ecophysiology of High Salinity Tolerant Plants

This volume presents new and additional information about the physiology and ecology of halophytic plant species and saline ecosystems. The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reprod

Dedication of this volume We wish to dedicate this volume to the many scientists who are involved in the research of high saline tolerant plants. It is through their effort that our knowledge of the mechanisms of saline tolerance is being understood. They are the ones who find high saline tolerant plants and evaluate their possible value in reclamation and economic use.
