    Researches concerning the production of tobacco seedling in Float system using trays with cells

    DIMA A.; CIRNICI M.; CIUPERCA A.; MILITARU D.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    During 1996-1997 a programme for obtaining tobacco seedlings by unconventional methods was conducted in Romania. The tests were made in three experimental fields of the Central Research Station for Tobacco Growing and Industrialization in Bucharest,...

    Types of Virginia Bright tobacco barns (or other vegetable materials) made in Romania

    RAC-HRISTOV C.; MARINESCU L.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    To be used in industrialisation process, green leaves of Virginia tobacco have to be harvested at proper time and then put to a yellowing, curing and fermentation technology treatment. When the green leaves are harvested the assimilation phenomenon...

    Using haploidy by androgenesis and embryoculture in tobacco breeding

    CIUPERCA A.; CIRNICI M.; DIMA A.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    In order to fulfill the main purposes of tobacco breeding (high yield potential, superior chemical and industrial quality, resistance to the main diseases of tobacco), the creation of a large genetic variability is needed. The classic methods for the...

    New tobacco genotypes obtained through in vitro manipulation of microspores

    PATRASCU M.; IOAN E.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    Genotypes with new genetic combinations were obtained by using "in vitro"cultures of microspores derived from inter- and intraspecific hybrids in F1 and F2. Dihaploid isogenic lines with superior production and quality characteristics are used as...

    Concentration of semi-volatile components in cigarette smoke by puff number

    SAWADA H.; KAWAMOTO J.; KOTANI M.
    Daicel Chemical Industries Ltd. Filter Products R&D, Osaka, Japan
    The filtration efficiencies of cellulose acetate charcoal filters for removal of such semi-volatile compounds as acetaldehyde, isoprene, acetone, benzene, and toluene were studied. Acetaldehyde deliveries on a per puff basis were determined for the...

    Dihaploid-type isogenous Lines and their use in tobacco quality improvement

    PATRASCU M.; EUGEN I.; DECULESCU G.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    Isogenous lines were obtained by doubling the chromosomal set of androgenetic haploids achieved byïn vitro"anther culture derived from inter- and intraspecific Nicotiana hybrids that were in the F1-F4 generation. Dihaploid genomes that include...
