Micropropagation of Wrightia Species

Abstract

The genus Wrightia belongs to the Apocyanaceae family and encompasses 32 species. This genus has many pharmacological properties and is used for many of the human ailments in the traditional systems of medicine. It also has commercial importance for its timber, dye, etc. Due to its commercial importance, some of the species of this genus, like Wrightia tinctoria and W. arborea are overexploited and have become endangered. There is a need to conserve these species. One of the techniques to conserve plants and multiplication is micropropagation. In this chapter, regeneration studies that include collection, sterilization, shoot and root generation, and acclimatization of Wrightia tinctoria and W. arborea are described.
