The Influence of Dicamba on Somatic Embryogenesis and Frequency of Plant Regeneration from Cultured Immature Embryos of Wheat (Triticum aestivum L.)

An investigation was made to discover the influence of dicamba on the somatic embryogenesis of winter wheat cultivars‐. Immature embryos of Triticum aestivum cv, ‘Sage’, ‘Caribo’ and ‘Kanzler’ were cultured, on modified N6‐medium with the addition of 1 mg/13,6 dichlor‐2‐methoxy benzoe acid (dicamba). The young embryos were placed with the embryo axis on to the medium. Under this condition the scutella of the embryos at different stage of development produced compact calli and embryoids which regenerated plants with a high frequency (70 %) four to: six weeks later. The results suggest that dicamba could be of value in the induction of somatic embryogenesis.
