However, the cork oak sector may be at risk due to climatic and economic pressures on cork oak forests, affecting both the quantity and technological quality of products. At some sites, irrigation may present a solution for stimulating cork growth and thereby increasing production. This study presents an initial approach to characterizing cork grown in a forest stand associated with a specific water regime, by comparing cork growth on two plots\u2014irrigated and a traditional rainfed\u2014over an initial five-year period. Samples of cork tissue were analysed and several parameters were\u00a0set: cell area, diameter, cell-wall thickness, number of cells, porosity, growth, and density. Irrigation plot samples showed on average: 25.83\u2009\u00b1\u20093.74\u00a0mm thickness, 5.17\u2009\u00b1\u20091.49\u00a0mm cork-ring width, 0.149\u2009\u00b1\u20090.041\u00a0g.cm<sup>\u22123<\/sup>\u00a0density, 13\u2009\u00b1\u20093.4% porosity coefficient in the tangential plane, 407.58\u2009\u00b1\u2009268.22\u00a0\u00b5m<sup>2<\/sup>\u00a0cell area in the tangential plane and 887.80\u2009\u00b1\u2009449.14\u00a0\u00b5m<sup>2<\/sup>\u00a0in the transverse plane, a total number of cells of 1232\u2009\u00b1\u2009147 per mm<sup>2<\/sup>, and 1.03\u2009\u00b1\u20090.30\u00a0\u00b5m cell-wall thickness; whereas traditional rainfed plot samples presented: 21.33\u2009\u00b1\u20095.48\u00a0mm thickness, 3.08\u2009\u00b1\u20091.44\u00a0mm cork-ring width, 0.167\u2009\u00b1\u20090.068\u00a0g.cm<sup>\u22123<\/sup>\u00a0density, 10\u2009\u00b1\u20093.5% porosity coefficient in the tangential plane, 304.31\u2009\u00b1\u2009205.83\u00a0\u00b5m<sup>2<\/sup>\u00a0cell area in the tangential plane and 752.45\u2009\u00b1\u2009398.94\u00a0\u00b5m<sup>2<\/sup>\u00a0in the transverse plane, a total number of cells of 1481\u2009\u00b1\u2009153 per mm<sup>2<\/sup>, and 1.204\u2009\u00b1\u20090.327\u00a0\u00b5m cell-wall thickness.
