Efficient in vitro regeneration of shoots by using hypocotyls explants of quinoa. (A) Seeds germinated aseptically in MS medium without hormones after 3 d (bar = 2.00 cm); (B) Callus induced in MS medium with 0.2 mg/L BA and 2 mg/L NAA after 21 d (bar = 1.00 cm); (C) Callus of hypocotyl induction in MS medium with 0.2 mg/L BA and 2 mg/L NAA after 21 d (bar = 1.00 cm); (D) Callus were subcultured in MS medium supplemented with 1 mg/L BA, 0.1 mg/L NAA and 0.2 g/L proline after 28 d (bar = 0.70 cm); (E) Differentiation of callus in presence of MS medium with 1 mg/L BA, 0.1 mg/L NAA and 0.2 g/L proline after 28 d (bar = 0.85 cm); (F) Adventitious shoots differentiated in MS supplemented with 1 mg/L BA, 0.1 mg/L NAA and 0.2 g/L proline after 28 d (bar = 1.00 cm).
