RAC Data for the Vectorized Root System of a Young Oak Tree

Share:

Description

For each observation date, this dataset 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.

Usage

1

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 first-order root having no parent root, its value in this column is set to -1).

  • Ord: the branching order (equal to 1 for the first-order root, 2 for a secondary root (or a first-order lateral root), 3 for a tertiary root (or a second-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.
