Experiment to demonstrate negative geotropism in
aerial stem
The
Clinostat has a rotating pot like container mounted on an axis rod. A potted
plant is fitted horizontally on the Clinostat and rotated slowly which
completely eliminates gravity as all the sides of the plant are equally
stimulated. If the rotation of the Clinostat is stopped for a considerable
period of time then the tip of the stem is observed to curve and grow upwards
this proves that the stem tip is negatively geotropic (Figure 15.19).
