Biochemical changes during in vitro root formation in Tribulus terrestris were investigated in the callus derived from nodal explants on Murashige and Skoog’s (MS) medium supplemented with 1.0 mg/l 2,4-D+ 0.5 mg/l Kinetin. The callus maintained on MS medium fortified with 2.0 mg/l 2, 4-dichlorophenoxy acetic acid (2,4-D) + 0.5 mg/l Kinetin. The above callus subcultured on Murashige and Skoog’s (MS) medium + 2.0 mg/l α-naphthalene acetic acid (NAA). Metabolites like starch and total; soluble sugars decreased while reducing sugar, total phenol and total protein increased during root differentiation in callus. Enzyme activity viz. α-amylase, acid invertase, peroxidase and acid phosphatase increased during root differentiation.

Keywords: Tribulus terrestris Linn, Biochemical changes, Rhizogenesis, Callus.
