Abstract
SummaryThis study examined the hypothesis that enhancement of peach quality resulting from Regulated Deficit Irrigation (RDI) is caused primarily by changes in fruit physiology during development. Water deficit was applied during either stage II of fruit development (RDI-SII) or during stage II and postharvest (RDI-SII-PH), as compared with non-droughted (control) and postharvest (RDI-PH) treatments. Fruit from the various RDI treatments had significantly higher soluble solids concentrations and red colour at harvest than control fruit. While fruit respiration was not altered by any RDI treatment, ethylene production indicated sooner the onset of climacteric phase for fruit from RDI-SII and RDI-SII-PH than for control or RDI-PH fruit. Accordingly, greater ethylene production in detached fruit was related to their having experienced water stress during development. Ethylene production by RDI-PH fruit did not change, but their quality did in terms of increased soluble solids concentration and improved skin colour similar to the RDI-SII treatment. This observation suggests that water-stress related changes occurring during fruit development are not the only factors involved in enhancing quality in RDI fruit.
