The presence of stems in cut tobacco is detrimental to cigarette quality, resulting in problems during production particularly on today's high-speed makers. Incomplete threshing and the use of unthreshed semi-oriental tobaccos can increase the stem...

148 French cigarette smokers (75 men, 73 women) had been subjected to smoking behaviour questionnaire. A principal component analyse followed by varimax rotations allowed to clearly point-out five factors which account for 58 % of variance:...

This paper deals with the theory of Addiction, which analyses and explains the common mechanism of many behaviours like for instance drugs' consumption, alcoholism, smoking habit, pathological gambling... This theory presents at the same time three...

This work is one contribution to the study of the mode of action of elicitins, fungal proteins inducing defense reactions on tobacco. The purpose concerns the involvement and the role of active oxygen species (AOS) in necrosis appearance associated...

In Switzerland approximately 730 ha of tobacco are grown, mainly on small family farms. The main growing area is located in the French-speaking part of the country, on altitudes ranging from 400 to 800 m above sea level. Approximately 95% of the...

The variability of P. tabacina A. populations was studied using the isoenzyme polymorphism of peroxidase, malate dehydrogenase and superoxidismutase. P. tabacina conidia from N. tabacum crops cultivated in distant areas of Europe...

In August 1993, unusual virus-like symptoms were observed in tobacco plants ( Nicotiana tabacum L.) of the cvs Myrodata Agriniou in the area of Agrinio (Central Greece). In 1994 and 1995 similar symptoms were noticed in the cv. Virginia in the area...

The high incidence of PVY on tobacco and the great variability of the viral strains involved were the reasons for setting up in 1996 a collaborative study on the matter within CORESTA. The objective was to evaluate the available varietal...

In the future, biological pesticides will be increasingly used in storage protection, and will complement or even replace conventional synthetic insecticides. In particular, the application of entomopathogenic viruses or fungi with a high specificity...

Accumulation of tobacco-specific nitrosamines (TSNA) is generally higher in air-cured tobacco than other types. Often there is a positive relationship between nitrite and TSNA accumulation and a negative relationship between rate of leaf moisture...
