    Effect of the degree of leaf ripeness at harvest on the yield, quality and chemical characteristics of Oriental (sun-cured) tobacco

    KARAIVAZOGLOU N.A.; PAPAKOSTA D.K.; DIVANIDIS S.
    Aristotle University of Thessaloniki, Greece; Tobacco Institute of Greece, Chemistry Dept., Drama, Greece
    Harvest date is one of the most important crop management practices affecting tobacco yield, quality and usability after curing. In a two-year field experiment, investigations were made into the effect of the degree of leaf ripeness at harvest on...

    Effect of plant growth regulators on maturation, harvesting, yield and quality of Oriental (sun-cured) tobacco

    KARAIVAZOGLOU N.A.; PAPAKOSTA D.K.; DIVANIDIS S.
    Aristotle University of Thessaloniki, Greece.
    Maturation and senescence in tobacco leaves can be accelerated or retarded by applied chemicals and plant growth regulators. Until now, research was focused only on the "yellowing" effect of ethylene on tobacco types other than Oriental. This work...

    Growth, maturation and senescence of Oriental tobacco leaves as affected by ethephon and inhibitors of ethylene biosynthesis

    KARAIVAZOGLOU N.A.; PAPAKOSTA D.K.; SFACIOTAKIS E.M.; DIVANIDIS S.
    Aristotle University of Thessaloniki, and Tobacco Institute, Laboratory of Agronomy, Laboratory of Pomology, Drama, Greece
    Ethylene is a gaseous plant growth regulator that it has long been known to promote fruit ripening and senescence of plant tissues. In contrast, aminoethoxyvinylglycine (AVG) and aminooxyacetic acid (AOA) both inhibitors of ethylene biosynthesis are...

    Distribution of polycyclic aromatic hydrocarbons between the particulate and the gas phase of mainstream cigarette smoke in relation to cigarette technological characteristics

    KALAITZOGLOU M.; SAMARA C.
    Aristotle University, Environmental Pollution Control Laboratory, Dept. of Chemistry, 541 24 Thessaloniki, Greece.
    Particulate- and gas-phase polycyclic aromatic hydrocarbons (PAHs) were determined in the mainstream smoke (MSS) of 59 manufactured cigarette brands (commercially available brands of unknown tobacco and blend type) with variable 'tar' yields and...

    Phosphorus fertilization impact on the yield and heavy metal concentration of tobacco variety KS82

    MATSI TH.; STROUTHOPOULOS G.; BARBAYIANNIS N.; TSOTSOLIS N.; LAZARIDOU TH.
    Aristotle University of Thessaloniki, Soil Science Laboratory, Thessaloniki, Greece.
    Phosphorus fertilization can contribute to the enrichment of soil with heavy metals, especially Cd, and to increase heavy metals content in tobacco. The objectives of this study were to evaluate the impact of phosphorus fertilization on heavy metals...

    Effect of liming on the growth and composition of the tobacco varieties Katerini and VE9

    MATSI T.; PAPADOPOULOS G.; STEFANOU S.; KANELLOPOULOS G.; BAHARIS N.; BARBAYIANNIS N.
    Aristotle University of Thessaloniki, Soil Science Laboratory, Thessaloniki, Greece.
    Liming of acid soils is expected to be beneficial for the growth of tobacco plants. The objectives of this study were to evaluate the impact of soil liming on the yield and composition of Greek Oriental Tasty and Virginia tobacco types. Field...
