Abstract
The effects of water stress on photosynthetic rate (Pn), intrinsic water use efficiency (WUE), chlorophyll (Chl) and ion content were investigated in three olive cultivars (Olea europea ‘Picual’, ‘FS-17’ and ‘Manaki’) for a four month period. Olive trees were subjected to three irrigation treatments, T1, T2 and T3 that received a water quantity equal to 100, 50 and 25% of crop evapotranspiration, respectively. Water-limited treatments reduced the Chl a and b concentrations in ‘Manaki’ whereas the concentration of Chl a was also reduced in the leaves of ‘FS-17’ exposed to T3 treatment. Water stress treatments were effective in reducing P(n) of the leaves of olive cultivars. As a result of the T2 treatment the WUE of ‘Picual’ and ‘Manaki’ was decreased whereas T3 treatment reduced the WUE in the olive plants. A water stress treatment- and genotype-depended reduction in P, Mg and B concentration was also observed in olive leaves. Under water stress conditions ‘Manaki’ appears to possess a certain capacity to increase leaf P, Ca, Mg and Zn concentrations.
