Callus, Organogenesis and Plantlet Formation in Tissue Cultures of Clitoria ternatea

Decoated seeds of Clitoria ternatea L. germinated on Murashigeand Skoog (Physiologia Plantarum 1962, 15, 473–97) basalmedium (BM) and differentiated callus and bipolar embryoids(two-step method) in low frequency. Calluses developed on lateralroots BM+KN(0.1 mg 1^–1)], on roots and hypocotyls BM+KN(0.5mg 1^–1)], and on roots BM+KN+IAA (0.5 mg 1^–1 ofeach)]. On basal medium with KN (0.5 mg 1^–1) and withKN+IAA (0.5 mg1^–1 of each), multiple shoot buds and embryoids(one-step method) were differentiated directly on split hypocotylsand roots. In the former, shoot buds developed even on unsplithypocotyls. Rhizogenesis on isolated shoot buds occurred efficientlyin BM+indole butyric acid (IBA 0.1 mg 1^–1) and BM+IAA(0.1 mg 1^–1 and 0.5 mg 1^–1). Profuse direct embryoidsand shoot buds developing on root systems are interesting morphogeneticphenomena rarely reported. Clitoria ternatea L., callus, embryoids, multiple shoot buds, regeneration
