Plants constitute the major source of raw materials as drugs used in treating various diseases of human beings. Because of wide spread toxicity and harmful side effects often caused by synthetic drugs and antibiotics, modern society increasingly preferring drugs of herbal origin. Genetic diversity of traditional medicinal herbs and plants are threatened by extinction as a result of over exploitation, environment unfriendly harvesting techniques, loss of growth habitats and unmonitored trade of medicinal plants. Propagation through seed is often limited for some medicinal plants because of poor seed production and germination ability. Further, propagation of these medicinal plants by conventional techniques like rooting of cuttings and grafting is not adequate to meet overgrowing demand. Hence, there is an urgent need to develop and adopt other propagation techniques like in vitro cultivation for large scale multiplication of medicinally important species. It offers many unique advantages over conventional methods of plant propagation. Ocimum citriodorus (O. ? citriodorum) (Lemon basil) belongs to the family Lamiaceae, is rich in aromatic essential oils and valuable for its medicinal, volatile and culinary properties. The present study describes the procedure for mass propagation and caulogenesis in O. ? citriodorum using nodal and leaf cultures. Shoot bud initiation was observed after four days of culture on full strength MS medium supplemented with nodal segments. Our regular observations revealed healthy growth of shoot sprouts into nodular buds in 10 days on MS media with 0.25-5.0mg/lit BAP and in combination with 0.25-5.0mg/lit IBA. An attempt has been made to study caulogenesis in Ocimum citriodorus L. using leaf and nodal explants inoculated on full strength MS medium with 0-5.0mg/ lit IAA and 0- 5.0mg/lit IBA. Calli bud formation occurred in both explants after one week. Effective and voluminous growth of callus was found after ten days of inoculation.
