Environmental factors and physiological responses of sweet cherry production under protective cover systems: A review

Climate change is increasing sweet cherry (Prunus avium (L.) L.) production under cover systems such as high tunnels, rain covers, and nets. The objective of this review was to provide an overview the environmental factors physiological responses involved in different types protective covering systems. most important affected by are photosynthetically active radiation (PAR), temperature, relative humidity, wind speed, which turn affect leaf gas exchange, plant water relations, tree growth, flower development, fruit quality. use has a positive effect on photosynthesis amount diffused PAR, but negative reproductive-vegetative balance due lower total PAR availability. Increases air temperature alter differentially flowering set, impacting positively ripening time cell division fruits. Plant status improved systems, allowing for greater tolerance deficit well potential expansion, with ensuing size, decreasing firmness Ca availability multiple observed suggest need adjust agronomic practices pruning, crop load regulation, irrigation, nutrition according these specific conditions.
