Measuring hydraulic conductivity.
Driven by gravity, measuring solution moves through the xylem of a stem segment. A balance (connected to a laptop) monitors the flow rate.
If you would like to find out more about the methods we use for measuring hydraulic conductivity, vulnerability curves, and wood anatomical traits, please look at Dr Anna Jacobsen's and Dr John Sperry's methods websites. Both have some very useful information. You may also email me if you have questions about methods.
