Abstract :This study was designed to micropropagate Vaccinium myrtillus L., a naturally growing bilberry, in the Turkish flora. In order to determine the most effective basal medium, lateral buds were initially selected as explants, which were then individually cultured in Murashige and Skoog medium, Anderson`s rhododendron medium, and McCown`s woody plant medium insert ignore into journalissuearticles values(WPM); supplemented with 1.0 mg L-1 zeatin in combination with either 0.1 mg L-1 indole-3-butyric acid insert ignore into journalissuearticles values(IBA); or 0.1 mg L-1 \alpha-naphthalene acetic acid. WPM, supplemented with zeatin and IBA, was found to be the most effective basal medium tested. As shoot regeneration ability highly depends on the medium and cytokinin concentration, WPM basal media containing various concentrations insert ignore into journalissuearticles values(0.5, 1.0, and 2.0 mg L-1); of 3 different cytokinins, namely zeatin, thidiazuron, and N6-[2-isopentenyl] adenine, were employed together with IBA insert ignore into journalissuearticles values(0.1 mg L-1); and were compared with basal media containing none of the growth regulators. In terms of shoot multiplication, 2.0 mg L-1 zeatin was found to be superior to the other tested growth regulators when combined with 0.1 mg L-1 IBA. WPM was also used as a basal medium for rooting and was supplemented with different concentrations of IBA insert ignore into journalissuearticles values(0.25-2.0 mg L-1); with or without activated charcoal insert ignore into journalissuearticles values(AC);. WPM supplemented with 0.5/1.0 mg L-1 IBA/AC was the best culture medium for rooting with 60% root formation.
