Changes in tomato seedlings root growth and morphology, induced by affinin treatment. Tomato seedlings were grown in a medium with or without the indicated affinin concentrations. After ten days, seedlings showed changes in: (a) primary root length (PRL), number of emerged lateral roots (eLRs), lateral roots length (LRL); (b) biomass expressed as fresh weight (FW) of five pooled shoots or roots with three biological repeats. Data were analyzed with one-way ANOVA and a Tukey test. Different letters (A–C) were used to indicate means that differ significantly (p ≤ 0.05) (n = 3).
