    An application of Fourier Transform Infrared (FT-IR) microspectroscopy to the study of cigarette manufacturing defects

    THOMPSON M.M.; IRELAND M.S.
    Lorillard Tobacco Company, Greensboro, NC, USA
    FT-IR microspectroscopy was used to investigate a common type of cigarette defect in which the filter separates from the tobacco rod. Infrared imagings of the adhesive located at this junction on the tipping papers from both defective and acceptable ...

    Genetic engineering of tobacco to lower cadmium content of leaves

    WAGNER G.J.; MAITI I.B.; NIELSEN M.T.; HUNT A.G.
    University of Kentucky, Dept. of Agronomy, Lexington, KY, USA
    Burley variety KY 14 was transformed with Agrobacterium tumefaciens harboring a binary vector containing the constitutive 35S promoter, the mouse metallothionein I gene, and a selectable marker gene. Metallothionein (MT) is an efficient Cd chelating ...

    Alkaloid biosynthesis in Nicotiana spp. with different alkaloid composition

    BUSH L.P.; FANNIN F.F.; HANRAHAN M.S.; NICHOLAS K.N.
    University of Kentucky, Dept. of Agronomy, Lexington, KY, USA
    Biosynthetic schemes have been proposed for tobacco alkaloids based upon incorportation of suspected precursors, but the addition of these precursors has not resulted in increased alkaloid accumulation in plants. Putrescine, cadaverine and nicotinic acid ...

    Evaluation of factors effecting germination and plant growth in float method of transplant production

    PALMER G.K.; ZELEZNIK J.M.
    University of Kentucky, Dept. of Agronomy, Lexington, KY, USA
    Float plant production is increasing in popularity as the system of choice for producing tobacco transplants. Approximately 5% of Burley tobacco transplants used in Kentucky in 1991 were produced by the float method. That figure will increase to ...

    Ignition propensity testing at different O2 concentrations

    NORMAN V.; WU E.C.; IHRIG A.M.
    Lorillard Tobacco Company, A.W. Spears Research Center, Greensboro, NC, USA
    Ignition propensity of cigarettes on soft furnishings is a function of oxygen availability. Oxygen availability, in turn, depends on air movement, and substrate permeability and geometry. Experiments are described where oxygen concentrations over a range ...

    Evaluation of an enzyme-linked immunosorbent assay for Phytophthora parasitica var. nicotianae in tobacco

    CSINOS A.S.; MILLER S.
    University of Georgia, Dept. of Plant Pathology, Coastal Plain Experimental Station, Tifton, GA, USA
    Diseased tobacco (Nicotiana tabacum L.) samples collected from a black shank nursery or commercial fields in 1988 and 1989 were used to compare enzyme-linked immunosorbent assay (ELISA) Phytophthora kits to standard culture plating identification ...

    Comparing six models of various complexity for calculating leaf area from measurements of leaf width and length

    MAW B.W.; MULLINIX B.
    University of Georgia, Dept. of Agricultural Engineering, Tifton, GA, USA
    Where there is a need to calculate the leaf area of tobacco, rather than measure it, leaf length and maximum leaf width are convenient input parameters for a mathematical model. Previous publications have proposed a simple relationship between length and ...

    Mechanical properties of flue-cured tobacco lamina as related to maturity and stalk position descriptors of market grade

    FOUTZ T.L.; ABRAMS C.F.; SUGGS C.W.
    University of Georgia, Dept. of Biology and Agricultural Engineering, Athens, GA, USA.
    Market grades were determined on a leaf-by-leaf basis for flue-cured tobacco harvested in 1986 and 1987. The leaves were placed into categories that described stalk position and maturity as defined by the USDA's elements of quality. Uniaxial quasi ...
