361	Mean(R) IAA	PTO	TO:0000257	After 3 days of treatment, plates were scanned with CCD flatbed scanners (EPSON Perfection V600 Photo, Seiko Epson, Nagano, Japan), and images used to quantify root parameters with FIJI, by using the tool ‘segmented line’ (Schindelin et al., 2012) as described in Ristova and Busch (2017). In particular, we quantified: primary root length on day 10 (P), growth rate of P after treatment (P2), branching zone or the length of P between the first and last visible lateral root (R), average lateral root length (LRL), and visible lateral root number (LR.No).			unit	UO	UO:0000000
