Deficit Irrigation as a Tool to Optimize Fruit Quality in Abbé Fetél Pear

Climate change is leading to higher plant water requirements and rootstock can play a role in tree adaptation, since the more vigorous ones are also likely be stress resistant. Pear trees of cv. Abbé Fetél grafted on BA29 (more vigorous) SYDO dwarfing) quince were irrigated according three different treatments: 110 C, 80 DI 60 DI, corresponding 110%, 80% 60% crop evapotranspiration rate (ETc), respectively. Shoot fruit growth, potentials, leaf gas exchanges dry matter content monitored during season. Fruit quality was evaluated at harvest after 6 months storage 1 °C. Results show how for both rootstocks, significantly decreased their stem (?stem) (?leaf) potentials as well exchanges. In SYDO, final size affected by irrigation, with lower values but BA29, no differences found between treatments. After storage, showed soluble solid content, while fruit, firmness irrigation level. conclusion, despite slight decrease size, reduced led features that maintained long period storage.
