In Xplo, some specific tools are available to explore plant architecture databases. On this page, you will see an illustration of various recurrent data extractions.
Data extraction can be performed with an interactive tool or by Groovy scripts. The interactive tool can be used by beginners, while Groovy scripts are more dedicated to experts.
Download and import the file “P6_I59_ni_L1P08.opf” . This coffee tree was completely described in terms of topology and dimensions of its elements. The decomposition scales of the plant (“Individual”) are the Axis scale (trunk and branches) and the Metamer scale: an axis is composed of Metamers and a Metamer is a component of an Axis. Metamers may axil Axes or Leaves.
First we need to select the branches. They are of ramification order 2 (the trunk being of ramification order 1).
Now we want to know the number of metamers per axis:
Now we want to know the position (or rank) of the axis on their bearer axis (i.e. on the trunk). We can do that in 2 operations:
Finally, produce a plot of the number of metamers in axes vs. the number of metamers on the trunk:
