Shoots of Camellta sinensis L. (1.5-2.5 cm in length) derived from sterile plantlets were cultured on MS medium containing BA at 0, 1, 2, 3, 4 mg/l combined with IBA at 2, 4, 6, 8 mg/l and activated charcoal (6 g/l). Before culturing, The shoots were dipped in a solution containing 500 mg/l IBA for 1 min. The shoots were cultured for      a period of 3 months with the first 2 weeks in darkness and then 10 weeks     in light conditions.

The result showed root formation occurred in that most of the medium combinations BA and IBA at the ratio of 0:2, 0:6 and   2:8 mg/1 yielded 100% root induction. However, the number and length of roots varied among the three media. The medium containing BA   and IBA at the ratio of 0:2, 0:6 and 2:8 mg/1 gave the average root number at 13.0, 16.6 and 15.5 roots/shoot and the average length of roots      at 1.9, 1.2 and 1.8 cm respectively.
