    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 stops, ...

    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 ...

    The influence of the mixed and organic fertilization on the soil biology, yield and quality of the Oriental tobacco

    PAUNESCU A.D.; STEFANIC G.; PAUNESCU M.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    Studies were made in 1982-1994 at the Experimental Station for tobacco in Voicesti, Vilcea, Rumania, using Oriental tobacco in crop rotation with organic, mineral and mixed fertilization. The cultivars and crop rotations for different periods were as ...

    New studies on the resistance of Oriental tobacco to the micromycete Chalara elegans

    PAUNESCU M.; PAUNESCU A.D.; STEFANIC G.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    The resistance of Oriental tobacco to black root rot caused by the micromycete Chalara elegans (Nag Raj et Kendrick) represents since 1990, a major purpose for breeding this type of tobacco in Rumania. Studies were conducted in laboratory, greenhouse and ...

    Studies on the behavior of Rumanian Virginia tobacco cultivars under infection by TMV and PVY

    PATRASCU M.; CIRNICI M.; PAUNESCU A.D.; BADICA S.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    Virginia tobacco in Rumania represents approximately 40 % of the total tobacco acreage. Virginia tobacco fields are placed on sandy, leaching soils in the south and the north-west of the country and also on smaller surfaces in the Center Ardeal region. ...

    Transfer of the resistance to TSWV from Nicotiana alata to other tobacco cultivars using in vitro culture techniques

    PATRASCU M.; PAUNESCU A.D.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    In order to transfer the dominant gene N, responsible for the resistance to TSWV, from Nicotiana alata to Virginia tobacco cultivars, interspecific hybridations were performed followed by in vitro culture of the immature embryos (around 7 days old), to ...

    The role of the bacterial rhizosphere in limiting the development of pathogenic micromycetes of the roots of tobacco plants

    PAUNESCU M.; PAUNESCU A.D.; STEFANIC G.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    Studies were conducted in 1993-1996 on the rhizosphere and the edaphosphere of the tobacco plants in conditions of root infection by pathogenic micromycetes in seedbeds (Chalara elegans, Rhizoctonia solani, Pythium de baryanum, Alternaria sp.). When the ...

    Influence of different levels of fertilization and moisture on some vegetation characteristics of the Oriental tobacco

    PAUNESCU A.D.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    Greenhouse experiments were carried out using Mitscherlich pots of 8 kg, filled with a 1:1 ratio mixture of soil and sand in order to evaluate the influence of different fertilization levels and moisture on some vegetation characteristics, chemical ...

    Agrobiological indices used to express the fertility state of the soils where tobacco is grown

    PAUNESCU A.D.; STEFANIC G.; PAUNESCU M.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    The authors define fertility as "The fundamental characteristic of the soil, which is a result of the vital activity of the micropopulation, of the plants roots, of the accumulated enzymes and from the chemical processes which generate biomass, humus ...
