Software

WinRHIZO program is offered in 4 versions (Basic, Regular, Pro & Arabidopsis)

The table below lists and explains the measurements and features offered by each version

WinRHIZO Basic

WinRHIZO Basic is a low cost entry level version. It produces only global measurements (average root diameter, total root length, area, volume and number of tips).

WinRHIZO Regular

WinRHIZO Regular has all features of the Basic model plus root morphology measurement as a function of user definable diameter classes. A root (length, area, volume) distribution graphic is automatically generated and is visible above the image.

WinRHIZO Pro

WinRHIZO Pro has all features of the Regular version plus link, topology, architecture and color analyses. The color analysis can produce root morphology as a function of color. It can also be used as a color area meter.

WinRHIZO Arabidopsis

WinRHIZO Arabidopsis has all features of the Pro version plus the ability to separate and analyse separately individual objects such as seedlings and leaves. It can do multiple root analyses per analysed image or regions of it.

Color Analysis with the Pro & Arabidopsis versions 

There are many possible applications for color analysis. Color analysis allows you to quantify areas of specifc colors or groups of colors and to measure root morphology as a function of color.

The operator first indicates to WinRHIZO the colors of the objects to be analysed and those of the surrounding background. This is done interactively by clicking the mouse in the image. During the image analysis process, WinRHIZO classifies the colors present in the image into different classes before making the morphological measurements. Color analysis will work if there are minimal color contrasts between the feature(s) you want to quantify and the surrounding background.

Link Analysis

Link Analysis is a study of the morphology and basic connectivity of roots segments. 

Red = External-External link
Yellow = External-Internal link
Green = Internal-Internal link
Blue = Isolated link (not connected to any link)

Topology Analysis is an extensive link connectivity analysis.

  • Magnitude, the number of external links extending from a link.
  • Path length, the number of links between a link and the base link (inclusively).
  • External path length, the sum of path lengths of all external links. It is the value for the complete root system (not per link).
  • Altitude, the largest path length.

The Develpmental Analysis identifies the order in which links are born from the base link as the plant grow.

Links of the same order can also be grouped per axis. An axis is a group of connected links of the same order.

Morphological data can be obtained for all orders and axes.

To analyse non-touching objects

Non-Touching objects are automatically identified and analysed individually (area, length, width, color). They must contrast with their surrounding background).

Touching objects...

... and too dense root systems (below) cannot be analysed individually (only total data is available). You can manually trace an outline around each seedling roots to get individual estimates but it will include some neighboring roots.

When the root system is very dense, it might not be possible to track down the main root and differentiate it from the laterals or it can be possible but time consuming (requiring interactive modifications). Also it might not work on all growing media (minimal contrast required) and with all scanners (we strongly recommend those we sell).
