Heat stress in cotton: Responses and adaptive mechanisms

Abstract

Cotton is vital cash besides fiber crop and plays pivotal role in economy in many countries. It thrives well under optimal temperature. Too high and too low temperatures affect badly its growth and yield. Too low temperature affects its germination and seedling establishment stages. Particularly, high temperatures influence many physiological and biochemical processes within cotton plant that result in poor seed cotton yield. Several researches in different agroecological zones employed different agronomic practices and modern breeding techniques to mitigate the heat stress for better cotton production. A bevy of literature regarding heat stress is presented here.
