    Investigation of the genetic variability induced in tobacco by experimental androgenesis

    PATRASCU M.
    Central Research Station for Tobacco Culture, Bucharest, Romania.
    The in-vitro culture of anthers has made it possible to obtain genetic variability in haploids, i.e. dihaploid lines derived from the same anther donor source. In Virginia-type tobacco, three intra-species hybrid combinations in the first generation were ...

    Utilization of the cultures in vitro in order to obtain tobacco genotypes with resistance to TSWV (Lycopersicum virus 3)

    PATRASCU M.; CIUPERCA A.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    Immature embryos, of 4-6 days, originated in pollination of some cultivars of tobacco with Nicotiana alata which has factors of genetical resistance to Lycopersicum virus 3 (LV-3), were cultivated. Through repeated tests, the best medium of culture proved ...

    The determination of Cu, Cd, and Pb in tobacco and tobacco products by stripping anodic voltametry

    GAIVORONSKI B.S.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    Stripping anodic voltametry has been used for the determination of Cu, Cd and Pb in tobacco and tobacco products. The sensitivity of the method and the established work conditions assure good reproducibility, permitting simultaneous determination of the ...
