Direct flower neoformation from superficial tissue of small explants of Nicotiana tabacum L.
On explants composed of 3-6 layers of epidermal and sub-epidermal cells of Nicotiana tabacum L. from the floral branches, it is possible to obtain mitoses followed very rapidly by meioses and the direct formation of anthers and pistil without any intermediate callus.
