Macroscopic adventitious rooting response on TCLs from various genotypes under different hormonal treatments. a–g Images under the stereomicroscope at the end of the in vitro culture (day 15) with IBA (10 μM) (a, d, f, g), IBA (10 μM) + Kin (0.1 μM) (c), IAA (10 μM) (b, e) or under HF (Insets in a, d, f, g). a Col-0 TCLs showing a poor callus formation and a lot of elongated ARs with hairs. b Col-0 TCLs with elongated hairy ARs, and high callus formation. c Col-0 TCLs with ARPs (arrow) and no elongated AR, and callus. d ech2ibr10 TCLs with a poor number of highly elongated ARs, and a very reduced callus formation. e ech2ibr10 TCLs with callus and elongated ARs. f–g wei2wei7 (f) and lax3aux1 (g) TCLs with a very few number of ARs which were not elongated. Insets in a, d, f, and g show the absence of AR formation in the HF-treated control explants. Bars = 1 mm (a-c, e-g, and insets in a, d, f, g), 2 mm (d)
