Effects of water stress on Sicilian olive cultivars.

An experiment was conducted to investigate the water relations of potted young olive trees (Olea europaea L.) cultivar ‘Biancolilla’, ‘Giarraffa’ and ‘Nocellara del Belice’ during water stress and after relief from stress. The aim was to highlight the different responses of the three cultivars and obtain a decision-making aid for planning an efficient watering schedule for potted plants grown in nurseries. Leaf water potential (Ψ), relative water content (RWC) and conductance to water vapour (gL) were measured in three-year-old plants. All three olive cultivars were able to survive the severe stress imposed by withholding water for three weeks, but gas exchange was strongly impaired and rec…
