Drought Stress Responses Of Seedlings Of Two Oak Species (Quercus Cerris And Quercus Robur), Ayşe Deli̇göz, Esra Bayar
Turkish Journal of Agriculture and Forestry
Effects of drought stress on growth, predawn xylem water potential (ψpd), osmotic solutes (soluble sugar and proline), and stomatal conductance were assessed in two oak (Quercus cerris L. and Quercus robur L.) seedlings. Seedlings of both species were subjected to three drought treatments with the following irrigation intervals: well-watered (control: irrigation every 2-3 days), moderate drought stress (irrigation every 15 days), and severe drought stress (irrigation every 30 days). Drought-stressed seedlings of Q. cerris and Q. robur had more negative predawn xylem water potential than their well-watered seedlings. In Q. cerris, root collar diameter and root dry weights were negatively …
