    Carbon footprint of Oriental variety Katerini 53

    KARAMANLIS K.
    Postgraduate Quality Assurance Course, School of Science and Technology, Hellenic Open University, Patra, Greece
    One of the human activities that aggravates global climate change is the agricultural sector, which produces 9% of carbon emissions. In this paper the carbon footprint of the Oriental variety Katerini 53 is calculated at the farmer's level based on...

    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...

    Analysis of the gas phase of cigarette smoke by gas chromatography with UV-diode array detection

    HATZINIKOLAOU D.G.; LAGESSON V.; POULI A.E.; STAVRIDOU A.J.; STAVRIDES J.C.
    Institute of Biomedical Research and Biotechnology, Athens, Greece.
    A gas chromatography method, coupled with diode-array photometric spectral detection in the ultraviolet region (170-330 nm), was developed for the analysis of the gas phase of cigarette smoke. Several column configurations and elution profiles were...

    The role of heavy metals in the soil upon the technological, chemical and smoking qualities of tobacco

    PAUNESCU A.D.; PAUNESCU M.; PANCIU A.; CÂRNICI M.
    Romanian Parliament, Deputies House, Agricultural and Forestry Commission, Bucharest, Romania.
    For tobacco, the soil represents the main source for the elements of mineral nutrition which are taken over through specific mechanisms and in the required ration for a normal metabolic activity. The purpose of this study is that of watching the...
