Study: Salt induced changes in Root System Architecture
DOI
Description
Salt stress affects not only plant size, but also plant architecture. In this study, we focused on salt stress-induced changes to Root System Architecture, by germinating the seedlings on vertical agar growth medium (no salt) and transplanting 4 days old seedlings into plates containing 0, 75 and 125 mM NaCl. The Root System Architecture phenotypes were quantified using EZ-Rhizo software for at least 4 replicates per accession per condition. The plants grown under control conditions were measured 4 days after transfer (8 days after germination), while plants growing at both salt stress conditions were measured 8 days after transfer (12 days after germination). The Root System Architecture traits include Main Root Length, Total Root Size, Lateral Root Length and ~ Density, as well as the length of individual zones (basal, branching, apical) on the main root.
