In vitro propagation by dormant, meristem culture of apricot (Prunus armeniaca L.) cv. Bakuoh junkyou was investigated by placing 1 mm shoot tops on four kinds of basal media (WP, MS. B5 and 1/2 MS) with cytokinins. Judging by survival rates and shoot length, the best medium was WP supplemented with BA or CPPU with 100% survival, whereas WP supplemented with 2 ip yielded 80% survival. For shoot proliferation, BA was most effective among 3 kinds of cytokinins tested, whereas zeatin and 2 ip were more effective for shoot elongation. IBA promoted rooting, the optimum being 2 mu-M; no rooting occurred without IBA treatment. The rooting ability of shoots increased with the number of subcultures; a maximum of 86.7% was attained after the 20th subculture
