    The influence of the physiologically active substances and of the natural bioregulators on tobacco seed, seedlings and plants

    DIMA A.; PAUNESCU A.D.; PAUNESCU M.; CIUPERCA A.; MILITARU D.C.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    The goal of the research was to improve the germination of tobacco seeds in order to obtain a healthy, vigorous, uniform seedling, ready to be transplanted in the shortest time. For the tobacco seed, cultivar Baragan 132, the following variants were used: ...

    New research concerning the production of tobacco seedlings in Romania using the float system with trays

    MILITARU D.C.; PAUNESCU A.D.; DIMA A.; COMAN E.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    The float system with trays was first tested in Romania in 1992, knowing its numerous advantages regarding the quality of the tobacco seedlings produced and the shortening of the obtaining period. After 1997, systematic research was conducted at the ...

    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 ...
