Plant Responses under Environmental Stress Conditions

Abstract

Considering increasing world population plants cultivation expanded in many poor areas. One of the most popular stress in soils is nutrient element depression. Moreover salinity and drought stress nowadays increased in the world. In order to improve plants tolerance to these conditions it necessary to realize plant mechanism under abiotic and biotic stresses. Plant tolerance to these stresses is dependent to their genetics, environmental situation and the combination of these two elements. This report gives an overview of the recent literature on the plants resistance limitation, physiological mechanism and symptoms of nutrient elements, salinity, drought and biotic stresses. The review will conclude by identifying several prospects for future researches aiming to improve the product resistance to the stress conditions.
