Climate change is a major threat to biodiversity, ecosystem services, and human well-being and will have impact on horticultural crops, due to erratic temperature regime, rainfall, more demand for water and enhanced biotic and abiotic stresses. Global warming has the potential to reduce available winter chill and thus greatly impact yield of temperate fruits and nuts. On the other hand, subtropical and tropical fruit tree species might have the opportunity to spread beyond their current latitudinal belts and to much higher elevations, while others will decline in increasingly adverse locations. Changes in plant phenology are one of the earliest responses to rapid global climate change and could potentially have serious consequences for fruit crops that depend on temperature and rainfall. However, the changes will not be only harmful, as CO2 concentration may enhance faster photosynthesis and increased temperature may hasten the process of maturity. Temperature increase affects photosynthesis directly, causing alterations in sugars, organic acids, and flavonoids contents, firmness and antioxidant activity. Hence there is a need to protect these valuable crops for sustainability against the climate change scenario.
