The dynamic pipeline: hydraulic capacitance and xylem hydraulic safety in four tall conifer species

Creator:: McCulloh, Katherine A., Johnson, Daniel M., Meinzer, Frederick C., and Woodruff, David R.
Abstract:: Recent work has suggested that plants differ in their relative reliance on structural avoidance of embolism versus maintenance of the xylem water column through dynamic traits such as capacitance, but we still know little about how and why species differ along this continuum. It is even less clear how or...
