Mature leaves of Torenia (Torenia fournieriLind.) were cultured on MS (Murashige and Skoog, 1962) medium supplemented with various concentrations of NAA (-naphthalene acetic acid) and BAP (N6-benzylaminopurine). Calluses, shoots, roots and somatic embryos occurred in different media, depending upon the ratios and concentrations of NAA and BAP. In the medium containing BAP alone (1.0, 3.0, 5.0 mg/l), explants were proliferated shoots reach to 100%. The maximum shoots formation was obtained in the medium containing 5.0 mg/l BAP (55.5±1.2).Whereas somatic embryos were formed on the media containing 1.0, 3.0 and 5.0 mg/l BAPplus 0.1 or 0.5 mg/l NAA. The highest somatic embryos production was occurred on the medium containing both 5.0 mg/l BAP and 0.1 mg/l NAA (59.2±3.7). The media containing NAA singly (0.1, 1.5, 3.0 mg/l) resulted in explants rich in roots and calluses. Morphogenesis monitoring under the microscopes displayed that somatic embryos were formed in the media containing 0.1 or 0.5 mg/l NAA plus 3.0 or 5.0 mg/l BAP and significantly confirmed that the upper leaf side was the origin of the shoots. The somatic embryos occurred without intervening callus phse. Somatic embryos automatically developed to seedlings without changing the medium. Shoots were rooted in the MS medium containing 200 mg/l activated charcoal. In vitroderived plants were acclimatized successfully and grew with uniformity as mother plant.
