Abstract: Stress (abiotic and biotic) factors reflect and specify the plant morphology and called as stress and have negative effect(s) on growth, development, quality, quantity and can reduce average plant productivity by 65 to 87%, depending on the plants and stage(s) and also give various permanent or temporary damage(s) according to length of exposed period, violence/density, developmental stage, age, etc. Researches have revealed that despite the advanced technology levels the fundamental basis of stress have not been understood comprehensively. Firstly taken response(s) has/have not yet fully understood and secondly any resistance or tolerance level of a variety/species because of their complex structure(s). But, this point is clear that with the help or assistance of multi-disciplinary approaches, it will be able to get promising result(s) in near future. This review focuses some of the ecophysiological responses of plants to biotic and abiotic stresses.
