Summary Leaf conductance, water relations, growth, and abscisic acid (ABA) concentrations in xylem sap, root apices and leaves were assessed in oak seedlings (Quercus robur L.)
Summary We monitored sap flow and estimated diurnal changes in transpiration rates of two trembling aspen ( Populus tremuloides Michx.) stands, located in the southern boreal
In contrast to many deciduous trees in which the total canopy develops in response to increased shoot growth in spring and early summer, fruit tree species that carry spurs may have
To assess how carbon uptake and water-use efficiency (WUE) are affected by water access, I monitored leaf and canopy gas exchange of neighboring Q.. agrifolia trees over a
In trees in the control and low-Pb soil treatments, Pb concentrations increased from the outer annual rings toward the stem center, whereas in trees grown in the soil
Measured daily photon flux (top), simulated canopy leaf area (thick line) and average daily CO 2 assimilation (thin line) in Source 2687 of Erythrina poeppigiana (bottom) during
Although LAI in the thinned plot did not increase between 1992 and 1993, a lower soil water content was observed during 1993 as a result of (1) a higher transpiration rate of trees
In this study, the hysteresis curves observed for tran- spiration rate and canopy conductance versus vapour pressure deficit and radiation were characterised under mist and
