Potometer an apparatus for measuring the rate of water uptake by a cut shoot or whole plant.
蒸腾计：通过茎切段或整个植物体来测量水分吸收速率的仪器。
This is normally closely related to the rate of water loss by transpiration and the potometer can be used to compare transpiration rates under different conditions.
通常与由于蒸腾作用而丧失水分的速率紧密相关，蒸腾计可被用于在不同条件下进行蒸腾速率的比较。
The value measured by Penman-Monteith method is very close to that measured with whole-tree potometer and that measured by heat pulse technique with errors less than 2%.
微气象法中午蒸腾值十分接近整树容器法与热脉冲法，其误差小于2％。
