Summary

A simple technique to evaluate accurately the effect of mechanical stress on root growth has been developed. The roots are allowed to grow against a predetermined pressure in the chamber of a pressure-plate apparatus. The root growth was studied against the applied pressures of 0, 2, 4, 6, 8 and 10 bar. A relationship of the form Y = aXb was observed between the rate of root elongation (Y) and applied pressure (X).
