WinRHIZO™, a root-measuring system with a unique overlap correction method.

In topology to measure roots with WinRHIZO Tron you must manually trace them with the mouse over the image. As you trace roots to indicate their presence, WinRHIZO Tron measures them and display complete morphological information on screen. Any root segment or node can be modified (moved, re-sized, deleted or added) by clicking the mouse or pressing keyboard keys. As you modify the roots, morphological measurements and data in files are automatically updated.The distribution of root length, area, volume or number of tips is displayed as a function of diameter in a graphic above the image. The color classes are the same as those used to draw the roots in the image. WinRHIZO Tron measures the real root diameter distribution rather than the average diameter as some other programs do. If a root segment encompasses three diameter classes, for example, the root length will be distributed among those three classes rather than only in the average class.
