dc.description.abstractThe oriental beech (Fagus orientalis Lipsky) is one of the important tree species among the broad-leaved species in Turkey. Tree social status can effect on competition and access to light, and on availability of local environmental resources, including water. The current study was conducted in 32 years old pure oriental beech stand. In May 2016, xylem water potential, soil water content and stomal conductivity were measured at six different time of day at the southern-facing crowns of dominant, intermediate and suppressed trees. The xylem water potential ranged between -0.18 and -1.28 MPa. The water potential was the highest in predawn, the lowest in the midday, and then it rises again. While all social classes were similar to predawn water potential, the water potential difference between the dominant and suppressed trees increased towards midday and decreased in the following hours. The dominant trees had the lowest water potential, while the suppressed trees had the highest. Soil water content decreased all soil layers throughout the day, especially in the top layer. The midday stomatal conductance was highest in the suppressed trees (16.53 mmol m(-2) s(-1)) and the lowest in dominant. trees (5.20 mmol m(-2) s(-1)). It can be concluded that oriental beech trees in different social status could have different eco physiological responses despite being in similar soil water conditions.en_US
