The division has initiated R & D in this area in 1986 and successfully demonstrated embryo / tissue culture protocols for the endangered blue vanda (Vanda coerula) of the Eastern Himalayas during the same year. Subsequently, the division has developed various in vitro culture methods such as embryo, meristem, root and pollen / anther cultures for the endangered taxa. Micropropagation protocols have been developed for about 40 medicinal and aromatic plants including tree species, 35 wild orchid species of the Western Ghats, agroforesry species which includes rattans, bamboos and wild banana and successfully conserved the species. The cryopreservation facility was established in 1993 and currently more than 30 plant species endemic to the Western Ghats have been maintained via various cryopreservation techniques. Eco-restoration programme was started in 1990 and reintroduced thousands of micropropagated orchids, rattans, bamboos and medicinal plants into the native habitat.
