Table 3.
Comparison of various traits measured by IJ_Rhizo, RhizoVision Explorer (RVE) and WinRhizo™ using simulated root images of dicot and monocot root systems (n = 294) of known measurements. Length and average diameter are given in millimetres, and surface area and volume are given in squared millimetres and cubic millimetres, respectively.
