Abstract:

Using a potometer to measure the movement of an air bubble due to transpiration.

Hints & Tips:

- Place your cuttings into a bucket of water immediately upon being cut. Cut the stem under the level of the liquid at an angle, this is important as it stops airlock from forming. 

- Cuttings should be at least 15 - 20 cm long with a stem diameter of approx 5 mm.

- Sycamore, beech, or maple are recommended for the woody shoots. Use leaves that do not have thick or waxy cuticles.
