Adventitious rooting in Arabidopsis thaliana TCLs under different hormonal treatments. a Percentage of TCLs, Col-0 ecotype, either at the initial stage or with macroscopic callus and ARs, after 15 days of culture without hormones (HF) or with IBA (10 μM) + Kin (0.1 μM), IBA (10 μM), IAA (10 μM) or Kin (0.1 μM). b Productivity of AR-forming TCLs evaluated as mean number (±SE) of ARs per TCL under either IBA (10 μM) + Kin (0.1 μM), or IBA (10 μM), or IAA (10 μM). ^a,d P < 0.01 difference with respect to the other treatments within the same developmental stage. ^b,c, P < 0.01 difference with respect to IBA + Kin and IBA within the same developmental stage. ^e, P < 0.01 difference with respect to IAA. ^f, P < 0.001 difference with respect to IBA + Kin. Columns with no letter or the same letter within the same developmental stage are not significantly different. N = 100
