Abstract
The method for mass propagation of one-year-old 'Nanko' mume (Prunus mume Sieb. et Zucc.) seedlings for rootstocks was investigated using tissue culture, and the following results were obtained: 1. The shoot growth on a WP basal medium was more suitable than that on MS or B5 basal media. 2. 6-benzyladenine (BA) at 5 or 10μM was most effective for shoot proliferation, whereas zeatin and N^6-(2-isopentenyl)adenine (2iP) were less effective at the same concentrations. 3. IBA or NAA treatment was more effective than IAA treatment on the number of roots and rooting percentages. 4. Rooted plantlets could be easily acclimatized under a mist condition.
