| photosynthetic, hydraulic and biomechanical responses of juglans californica shoots to wildfire. | leaf gas exchange and stem xylem hydraulic and mechanical properties were studied for unburned adults and resprouting burned juglans californica (southern california black walnut) trees 1 year after a fire to explore possible trade-offs between mechanical and hydraulic properties of plants. the co(2) uptake rates and stomatal conductance were 2-3 times greater for resprouting trees than for unburned adults. both predawn and midday water potentials were more negative for unburned adult trees, ind ... | 2010 | 20496153 |
