摘要: An efficient protocol was established for regeneration of Desmodium motorium via somatic embryogenesis. Embryogenic calli were induced from cotyledon segments (6 mm, 16 days old) lacking embryo axis, excised seedlings grown in vitro on Murashige and Skoog (MS) medium supplemented with indole-3-acetic acid (IAA) (2.9 μM) in combination 6-benzyladenine (BA) (4.44 8.88 μM). Differentiation embryogenic into globular heart-shaped embryos achieved transfer to hormone-free MS medium. When incubated 4 days BA (8.88 μM), 95% the matured torpedo cotyledonary stages minimum (10%) abnormalities. Modified basal without hormones containing half-strength macronutrients 0.88 M sucrose suitable germination mature embryos. Regenerated plantlets successfully transferred earthen pots survival rate 50%. Secondary embryogenesis observed when pre-existing at cultured various concentrations BA, adenine sulphate (AdS) abscisic (ABA) individually.
