In-vitro callus induction and multiplication of inter-nodal explants in plants Dicoma tomentosa and Alhagi maurorum

Abstract

Dicoma tomentosa and Alhagi maurorum are the two medicinal plants with fast in-vitro growth. Both the plants have high economic values. Both the plants were investigated on nodal segments and on leaves. The plants were cultured in five different conditions of medium ranging from MS1- MS5. The hormones were used in these mediums in different concentrations. BAP, NAA, Kinetin, and 2,4 D were use. The MS medium in combination with BAP (2.0 and 2.0mg/ml) with NAA 0.1 mg/ml with kinetin 0.25 mg/ml with 2-4 D were taken, where BAP 1 mg/ml with 2 mg/ml of NAA, BAP 2 mg/ml with 0.5 mg/ml of NAA showed better results with callus growth and root-shoot initiation. The best rooting medium found was MS medium supplemented with IAA and IBA 0.5mg/ each. The culture medium was used in different concentrations for estimation of primary metabolites. Maximum protein and lipid percentage were noticed in leaves of both the plants. It can be concluded that both the studied plants have high medicinal importance and can be used as raw material for industry.
