This book is an outcome of research carried out for 5 years at Department of Botany, University of Pune, India in association with Agricultural Faculty and Natural Resources, Islamic Azad University, Ahvaz Brach-Iran. The research was focused on effect of waterlogging stress on morpho-physiological characteristics of wheat. The book encompasses six chapters. Chapter-I is devoted on definition and causes of waterlogging, dimension of problem in world and adaptive mechanisms to waterlogging. Chapter-II is focused the previous work on this aspect. Chapter-III includes the various types of methodology used and crop management practices. Chapter-IV is devoted on observations and results of field and pot experiments. Chapter-V is devoted to discuss the results and probable morpho-physiological characteristics of wheat by various duration of waterlogging at different growth stages . Chapter-VI, summary and conclusion are given in nutshell in last chapter. This book will be a guideline for physiology, agronomy student, teachers, researchers and even farmers.
