This study was conducted to optimize different types and concentrations of amino acids on somatic embryogenesis induction, development and maturation of leaf explants in strawberry cultivars (‘Camarosa’, ‘Paros’ and ‘Kurdistan’). Calli derived from leaf sections were transferred onto MS medium with 1.0 mg/l 2,4-D + 0.5 mg/l BAP supplemented with 0.0, 50, 100, 150 or 200 mg/l concentrations of proline, alanine and glutamine. Stimulation of embryogenesis and embryo development was strictly dependent on the type and concentration of amino acid in the medium. Proline (100 mg/l) was much more effective than glutamine and alanine, on induction and development of somatic embryogenesis in all cultivars. Cultures grown on amino acid-free medium attained lower somatic embryos than cultures grown on amino acid treated medium. Low concentrations (50 mg/l) and high concentrations (200 mg/l) of amino acids tested were inefficient for embryogenesis induction as well as for somatic embryos development.
