1Purpose:
Xylem embolism is a common phenomenon in woody plants when subjected to water stress. Research has found a close relationship between the anti clogging ability of woody sapwood and the water consumption and drought resistance of trees. Studying the drought tolerance of trees (drought tolerance and drought resistance) can prevent the occurrence of xylem voids and clogging, thereby ensuring the normal operation of xylem water transport under drought stress. The XYL'EM measurement system is a device that can measure plant hydraulic conductivity and clogging rate. It can be used both in the laboratory and in the field (requires an additional 12V battery, 15AH or above is acceptable). 1 set of 12V power supply unit and temperature probe for temperature compensation. The XYL'EM measurement system can operate under low pressure (up to 1 meter of water column, 100 mbar) or high pressure (typically 3 bars, up to 7 bars). Adopting an integrated water container. There is a set of control valves on the main panel that can be used to select the high or low water pressure. The LCD screen can instantly display flow rate, water pressure, and water temperature. Communicate with a computer using an RS232 data cable and manage measurement data using professional data acquisition and analysis software.

IIPrinciple:
The XYL'EM measurement system uses a referenceThe "water pressure" method first measures the hydraulic conductivity of a section of the sample under low-pressure water flow (1m water column), and then continuously pours deaerated water into the sample at a certain pressure (with a built-in high-pressure storage tank that can provide 3bar high pressure) to saturate it with water. This infusion eliminates or dissolves the air contained in the cork tube. The ratio of initial hydraulic conductivity to fully saturated hydraulic conductivity provides a quantitative value for the level of embolism.
