摘要

Heat stress is known to be the second most significant abiotic stress after drought, negatively affecting the growth, productivity, and quality of fruit plants. Developing heat-tolerant genotypes is a current research priority due to the gradual increase in Earth’s atmospheric temperature every year. Fruit crops occupy a central position in horticulture and they contribute significantly to the profit sector of the food market, thereby boosting the economy. Due to the limited data on heat tolerance mechanisms specific to different fruit crops, it has been difficult to counter heat stress successfully in all cases. Heat stress can cause alterations at all growth stages of the plant—at physiological, biochemical, and genetic levels—resulting in severely diminished final edible produce. Heat stress effects are perceived at the cellular level through osmotic imbalance, leading to misfolding or damage of proteins, membranes, and reactive oxygen species (ROS), and a range of other molecular mechanisms. Heat stress tolerance is characterized by several protective mechanisms including scavenging of ROS, expression of heat shock proteins, production of transcription factors and chaperones, and accumulation of secondary metabolites and osmoprotectants along with various physiological adaptations at the plant tissue/organ level. Detailed knowledge of the mechanisms and impact of heat stress is essential for the development of counter-strategies to alleviate the effects of heat stress and to generate heat-tolerant plants. The present review focuses on the effect of heat stress in different fruit crops, including a detailed discussion of the underlying mechanisms involved. Conventional breeding techniques along with biotechnological approaches topped with molecular and omics methods are used to improve plant resilience to heat stress. Different management strategies implemented during heat stress in various fruit crops (i.e., heat-tolerant root stock, seed priming and bacterial seed treatment, canopy management, nutrient management by foliar spray with biostimulants, fruit bagging, foliar spray with osmoprotectants, antitranspirants, growth regulators, bark painting, mulching, and soil moisture conservation) work as rescue techniques to improve the quantity and quality of harvested crops.
