Abiotic Stress Tolerance in Crop Plants

Stress environment is one of the major limiting factors for the crop productivity. Stress can be classified into biotic and abiotic according to the nature of the responsible factor. Abiotic stress refers to the stress caused by water, salt, oxygen, CO2, light, temperature, nutrients, etc. About 10% of the arable land of the world alone are categorized as free of abiotic stresses. The remaining include, 20% under some kind of mineral stress, 26% affected by drought stress, 15% by freezing stress and the remaining area under other type of stresses. Extensive information on various aspects of abiotic stresses has been generated in the recent past. However, this information remains scattered. Hence an attempt has been made to bring an exhaustive collection of various stresses among different crops. This book provides comprehensive uploaded coverage of key aspects of abiotic stresses and their management. The authors of this book are experts in their own field of specialization and the topics covered in this book include, Global warming, High temperature stress, Drought including molecular approaches, Salt tolerance and abiotic stress on seed quality. This book will serve as a compendium for understanding and management of various abiotic stresses which will be highly useful for scientists and research scholars of agriculture.
