Abstract:

 


The 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.
