The ability of apical axillary buds of 15–30 and 1–3 years old walnut trees to morphogenesis in vitro was studied. Adventitious shoot formation was induced on MS- media containing IBA (0,01 mg/1) and 6-BAP (1 mg/l) after 12 weeks of cultivation (including two subcultivations after 2 and 6 weeks). Propagated shoots were pretreated in liquid MS-medium with IBA (1; 5; 10 mg/1) and sucrose (60 g/l) during 6 days in dark. Rooting of the walnut shoots was achieved on hormone free MS-medium (macro-salts were dissolved 1/4) with agar.
