    Effect of storage method and duration on germination of pelleted flue-cured tobacco seed

    AMANKWA G.; MISHRA S.; SHEARER A.D.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Delhi, Ontario, Canada
    The amount of pelleted seed remaining after seeding can be quite substantial in certain cases, requiring proper storage if the seed is to be seeded the subsequent year. This study was conducted to determine the best storage condition that would maintain ...

    An evaluation of hybrid and pure line cultivars of flue-cured tobacco for cured leaf yield and quality

    AMANKWA G.A.; MISHRA S.; SHEARER A.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Tillsonburg ON Canada
    Currently, hybrids account for about 57% of the flue-cured tobacco acreage in Canada, since the first release of a hybrid cultivar in 2006. Grower expectations for hybrids are high in terms of the potential for improved cured-leaf yield and quality which ...

    Evaluation of MCW-2 (fluensulfone) as a nematicide in flue-cured tobacco production

    SAUDE C.; BRAMMALL R.A.; SHEARER A.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Tillsonburg ON Canada
    Field trials were conducted in 2012-2014 to evaluate the effects of three rates (1, 2 and 4 kg a.i./ha) of MCW-2 (a.i. fluensulfone) on plant growth and yield, and populations of Root-lesion (RLN) (Pratylenchus penetrans) and Stunt (Tylenchorhynchus spp.) ...

    Evaluation of mustard bran soil amendments for the control of root-lesion nematode (Pratylenchus penetrans) and effects on selected soil fungi in flue-cured tobacco production in Ontario, Canada

    BRAMMALL R.A.; SAUDE C.; SHEARER A.D.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Tillsonburg, ON, Canada
    The root-lesion nematode (RLN) is an important pest in flue-cured tobacco production in Canada which is controlled through the pre-planting application of chemical soil fumigants. Mustard green manure and the incorporation of mustard by-products into soil ...

    Evaluation of two flue-cured tobacco F1 hybrids with different sources of male sterile cytoplasm

    AMANKWA G.A.; MISHRA S.; SHEARER A.D.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Tillsonburg, ON, Canada
    Hybrid cultivars are growing in importance in flue-cured tobacco production in Ontario, Canada. The first F1 hybrid cultivar was released in 2006, and today hybrids account for about half of the flue-cured tobacco acreage. Cytoplasmic male sterility (CMS) ...

    Color and aroma of tobacco: a facilitated approach for their objective evaluation in Oriental tobaccos and for cultivar classification within Virginia and Oriental tobacco types

    DAGNON S.; EDREVA A.; VLADOVSKA A.
    Tobacco and Tobacco Products Institutes, Plovdiv, Bulgaria; D. Kostov Inst. of Genetics, Bulgarian Academy of Sciences, Sofia, Bulgaria.
    In the routine practice the evaluation of colour and smoke aroma, major qualitative characteristics of tobacco, is mainly based on organoleptic estimates by expert panels, with this suffering from subjectivity, high costs and health hazards. We propose a ...
