In addition to the increase in atmospheric CO2, some&lt;br/&gt;models predict increased drought in Mediterranean areas as a consequence&lt;br/&gt;of global change. Thus, to determine how increased atmospheric CO2&lt;br/&gt;interacts with increased water stress and affects Mediterranean plant&lt;br/&gt;growth is an important achievement. The present study analyses how helm&lt;br/&gt;oak (Quercus ilex L.) seedlings are affected by both elevated CO2 and&lt;br/&gt;increased water stress. The CO2 concentrations were supplied in&lt;br/&gt;controlled environment chambers (350 and 500 ppm CO2), and water stress&lt;br/&gt;was performed according to a Mediterranean pattern (Potential&lt;br/&gt;Evapotranspiration to Rainfall ratio). The increased water stress was&lt;br/&gt;attained by watering half of the Mediterranean reference pattern.&lt;br/&gt;Results show that the positive effects of elevated CO2 on photosynthesis&lt;br/&gt;and growth are counteracted by increased water stress.</style></abstract></record></records></xml>
