Abstract

Dormant bud explants taken from mature trees of Japanese persimmon cv. Hiratanenashi were established successfully on modified Murashige and Skoog's medium with nitrate reduced to half-strength [MS (½NO3)] or woody plant medium, both supplemented with 22.2 μM (5 mg°liter−1) BA. Shoot proliferation in subcultures also was best at 22.2 μM (5 mg°liter−1) BA in MS (½NO3) medium, but growth was of the rosette type. Shoot elongation, however, was stimulated the most in the same medium supplemented with 24.6 μM (5 mg°liter−1) 2iP instead of BA. Rooting of the proliferated shoots was enhanced by the treatment with IBA at 1.23 mM (250 mg°liter−1). Chemical names used: N-(phenylmethyl)-1H-purin-6-amine (BA), N-(3-methyl-2-butenyl)-1H-purin-6-amine (2iP), 1H-indole-3-butanoic acid (IBA).
