In Vitro Morphogenetic Responses of a Tropical Tree Terminallia arjuna L.

Plantlets via somatic embryogenesis have been produced from leaf derived callus of mature Terminallia arjuna L. tree when cultured on Murashige and Skoog's (MS) medium containing 2.3μM- 23.0μM of 2,4-D. However, the formation of white globular embryos was triggered by the withdrawal of 2, 4-D from the nutrient medium after the exposure for a certain period of time. Embryogenesis and further embryo development as well as secondary somatic embryo formation was preceded in the nutrient medium containing 0.11μM to 0.44μM of BAP.
