Heat Stress Effects in Fruit Crops: A Review

Heat stress is one of the most ominous abiotic factors which limit the productivity and quality thereby resulting in to huge economic losses. High temperature affects the morphological, anatomical and physiological and biochemical changes in plant system. The success in overcoming heat stress is limited owing to poor knowledge of heat stress during critical stages of fruit crops. There is urgent need to improve heat stress tolerance by using traditional breeding and transgenic approach. In this paper, we have discuss the effect of heat stress and possible management techniques viz., selection of fruit crops, cultivars, rootstocks, canopy management, irrigation, nutrient management, mulching, growth regulator and use of bagging and film spray etc. which can be used to alleviate heat stress in fruit crops.
