ch7rac: RAC Data for the Vectorized Root System of a Young Oak Tree
Description
For each observation date, this data set obtained with Data Analysis of Root Tracings summarizes the length of each root constituting the vectorized root system of a young oak tree (Quercus robur L.) growing in a vertical rhizobox.format
A data frame containing the following columns:
- Root: the identification number of each root constituting the vectorized root system.
- Mother: the parent root identification number (a primary root having no parent root, its value in this column is set to -1).
- Ord: the branching order (equal to 1 for the primary root, 2 for a secondary root, 3 for a third order lateral root, etc).
- DBase: the distance between the branching point to the parent root base.
- DApp: the date of emergence.
- Lengths: the root length at each observation date (in pixels). The number of column "Lengths" is equal to the number of observation dates.
