    Agrobacterium rhizogenes induces growth of aberrant roots with bacterial T-DNA; some roots can spontaneously regenerate into plants carrying T-DNA fragments. T-DNAs contain genes that are expressed in plants which normally lead to root growth and to...

    Stalk position effect on harmful and potentially harmful cigarette smoke constituents in Burley tobacco: a case study

    VERRIER J-L.(1); DESTRUHAUT S.(2); COLARD S.(3)

    Influence of transplanting and harvesting date on the agronomic and chemical characteristics of flue-cured tobacco

    COURT W.A.; HENDEL J.G.; POCS R.
    Chem. Lab. Agric. Canada, Res. Station, Delhi, Ontario, Canada.
    A field experiment was conducted for two years on a Fox loamy sand soil to study the effects of transplanting and harvesting dates on selected agronomic, physical, and chemical characteristics of flue-cured tobacco (Nicotiana tabacum L.) grown in...

    Laboratory assays for evaluation of products for control of pole rot of tobacco caused by Rhizopus arrhizus

    REELEDER R.D.
    Agric. Canada Res. Station, Delhi, Ontario, Canada
    Procedures for the rapid screening of chemical products for control of pole rot of tobacco were developed. A leaf disk assay was developed using disks cut from mature leaves selected from greenhouse-grown plants ( Delgold ). Leaf disks were placed in...
