Abstract
Introduction: Teak tree is a precious wood species, due to its durable wood quality, widely used in construction and industry, ranked first in the world.
Aim: An improved micropropagation system has been developed for teak in pilot scale
Methods: Shoot tips placed on WPM medium supplemented with 0.1 - 0.05 mg/l BA for shoot induction. Shoots were used as culturing materials for far micropropagation studies
Results: WPM is basic media cultivation for this purpose. The admenments of BA (0.1 mg/l), and others as Tyrosin (10 mg/l), Adenine sulfate (10 mg/l), coconut water (10 %), position of internode, volume of cultivated plastic box (500 ml), lighting intensity (34,2 mmol/m2/s) and increasing air exchange leading high efficiency for in vitro raised micro shoots. Its reaches 100 % for rooting and 96.5 % for hardiness acclimatization
Conclusion: A rapid micropropagation technology for teak under pilot scale was set up.
