Faced with the growing problems of soil salinity, scientists look for potential solutions to provide food security and and reduce poverty. A thourough understanding of the ecophysiological processes that help plants or crops adapt to environmental stressess is therefore crucial.This book is arranged into five sections which cover information on the ecophysiology of plants in relation to salinity. The book demonstrate how salinity affects growth, stomatal conductance,transpiration, photosynthesis and mineral nutrient uptake in plants especially in young avocado plants. This book is suitable for both plant ecophysiologists, environmental scientists, botanists and horticulturists.
