영문 초록

This study was conducted to determine the effect of a light-emitting diode (LED) on in vitro shoot growth and rooting in teak (Tectona grandis L.). In the experiments with apical bud explants, the greatest shoot elongation (3.2 cm) occurred when they were cultured on DKW medium under 50% blue and 50% red LED mixture (BR), whereas no differences in growth were observed in different light sources (florescent light [F] or BR) or media (MS or DKW). The highest number of shoot multiplication (2.4/explant) or elongation (4.94 cm) was achieved with 0.5 or 1.0 mg/L 6-Benzyladenine (BA) treatment under BR. In addition, the best rooting rate (93.8%) or root length (1.3 cm) was recorded with 0.5 mg/L indole-3-butyric acid (IBA) treatment under BR, and the highest root induction (3.1/explant) was observed in 0.2 mg/L IBA under BR. The in vitro rooted plantlets were hardened and survived well on soil.
