First, a ‘batch process’ was carried out which automatically ‘thresholds’, ‘skeletonises’ and ‘builds segments’ of all images in bulk. Then, the the root system of individual images was measured by placing a marker at the ase and tip of the primary root. From these markers, RR2D automatically calculates primary root length (PRL), lateral root length(LRL) of all laterals and lateral root number (LRN).",,primary root BIP/EI,Lateral root length,cm,"RootReader2D (RR2D, Clark et al., 2013) was used to analyse images.

Root lengths were previously derived from image analysis based - measurements from RR2D. (MO_001),,root BIP/EI,Mean lateral root length,cm,The average of length of lateral roots was derived from dividing lateral root length (LRL) by lateral root number (LRN). Lateral root lengths and numbers were previously derived from image analysis based - measurements from RR2D.
