Callogenesis and rhizogenesis of Viola odorata L.
Journal Title: Biotecnología Vegetal - Year 2020, Vol 20, Issue 4
Abstract
Viola odorata L. is a medicinal plant and source of different secondary metabolites. It has been proven that callus culture can be used as an effective method for multiplication of medicinal plants. The aim of this paper was to develop a protocol for callogenesis and rhizogenesis in V. odorata. Petiole and leaf were used as explants for callogenesis. Significant callus induction was observed on MS medium supplemented with 2 mg l-1 2,4-D + 2 mg l-1 NAA+30 mg l-1 adenine sulphate. It was produced hard and embryogenic callus with white and greenish colour. The highest fresh weight of callus was obtained with 2.5 mg l-1 2,4-D + 2.5 mg l-1 BAP (8.093 g) and the lowest with 0.5 mg l-1 BAP (0.295 g). Besides, the highest dry weight of callus was achieved with 2 mg l-1 2,4-D +2 mg l-1 NAA+30 mg l-1 adenine sulphate (0.755 g) and the lowest with 0.5 mg l-1 TDZ (0.045 g). Roots from callus were induced using IAA and IBA. Maximum number of roots (10.60) and highest root length (2.92 cm) were recorded after 15 to 20 days in culture medium with 1.5 mg l-1 IBA. Present study reveals that this protocol could be used for in vitro callogenesis and rhizogenesis of V. odorata.
