Influence of sources and concentrations of plant growth regulators on callus induction and subsequent indirect plantlet regeneration of gerbera. a Induction of callus formation in the form of swelling of the injured sections of leaf due to cellular expansion (bar = 5 mm) [inset: the injured sections on leaf]; b proliferation of organogenic callus (induced from MS + 1 mg/l picloram) (bar = 5 mm); c proliferation of embryogenic callus (induced from MS + 1 mg/l 2,4-D) (bar = 5 mm); d proliferation and subsequent necrosis of callus (induced from MS + 1 mg/l NAA) (bar = 3 mm); e initiation of shoot primordia from nodular callus (induced from MS + 1 mg/l picloram) in MS + 1.5 mg/l kinetin (bar = 10 mm); f subsequent elongation of regenerated shoots (bar = 10 mm); g elongation, multiplication, and proliferation of regenerated shoots (bar = 25 mm); h root initiation and elongation from regenerated and isolated shoots in MS + 1.5 mg/l IAA (bar = 25 mm)
