Initially, of the different cytokinins tested (BAP, TDZ and Kin), none gave shoot regeneration alone, but BAP in combination with IAA induced shoot induction. The regenerated leaf explants showed a positive response for the initiation of shoot-bud regeneration in the IAA/BAP combination treatments (Fig. 1A). The morphogenic response of leaf explants (leaflets with petioles) on a MS medium supplemented with different IAA/BAP combina- tions are presented in Table 1. The IAA/BAP combinations tested for in vitro culture establishment resulted in callus production and adventitious shoot induction after 28 days of culture initiation. Initially, the leaf explants enlarged and developed globular structures on the margins as well as the mid-rib region of the leaves within 2 weeks of culture on a MS medium supplemented with 1 mg l
