The quantification of cotton root system using customized image-processing software. a An example of time-course images of cotton root system. The red line is primary root (PR) skeleton and the blue line is lateral root (LR) skeleton. b The root depth, root width, total root area, convex hull area, PR length and LR area of cotton root system over time. DAT: Days after transplanting. c The time-course images are superimposed as a color image with outline as the pseudo-landmarks of the root system. Colors indicate time sequence. d The vertical distribution of maximum root width. Colors indicate time sequence. e The automatic segregated sections of PR and lateral root groups (LRGs). Colors are used to distinguish PR sections and LRGs. f The automatic segregated sections of PR and the LRGs separated by hand. Colors are used to distinguish PR sections and LRGs. g The pseudo-mean-length of LRs in each section of PR. Colors indicate time sequence. h The trajectory of rearranged LRGs in different PR sections. The red line indicates full trajectory and the black line indicates the trajectory of 95% cumulative length
