- the leaf explants are taken from plants cultivated in a greenhouse or in vitro and regenerated according to the technique of leaf discs (Horsh & coll., 1985) in three successive stages: the first comprises the induction of shoots on a medium supplemented with 30 g / 1 of sucrose containing 0.05 mg / 1 of naphthylacetic acid (ANA) and 2 mg / 1 of benzylaminopurine (BAP) for 15 days.
- ANA naphthylacetic acid
- BAP benzylaminopurine
- the shoots formed during this stage are then developed for 10 days by culture on an MS medium supplemented with 30 g / l of sucrose but containing no hormone. Then take developed shoots and cultivate them on an MS rooting medium with half content of salts, vitamins and sugar and containing no hormone. After about 15 days, the rooted shoots are put in the ground.
