Bull. Spec. CORESTA Congress, Lisbon, 2000, p. 113, APOST12 Haskovo 2 - New variety of Virginia tobacco IANTCHEVA A.M.; IORDANOV V.I.; NIKOVA V. Complex Experimental Station, Haskovo, Bulgaria. Virginia tobacco is a relatively new culture for Bulgaria. Usually only 2 or 3 FCV varieties are cultivated under a variety of soil and climatic conditions, which did not permit to develop their potential possibilities for obtaining a typified raw...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 113, APOST14 New Bulgarian high-quality varieties of Oriental tobaccos IANTCHEVA A.; IORDANOV V. Complex Experimental Station, Haskovo, Bulgaria. The increased international demand for Oriental tobacco and the industrial conditions of its production require the creation of new varieties of exportable quality. The purpose of our programme was to select and introduce in the production new...
Bull. ARN, 1992, p. 35-52., ISSN.1146-6200 Description of the chemical and physical behaviour of environmental tobacco smoke during the ageing of the smoke. Corraboration of transfer between the liquid and gas phases of tobacco smoke ESQUIER F. CERTSM-DCAN, Toulon-Naval, France The aim of this study was to assess the relationship between the level of contaminants in the atmosphere of a closed chamber and the number of cigarettes smoked, and to follow the changes in particulate and gas phases of the atmosphere with time. The...
Bull. ARN, 1989, p. 34-41., ISSN.1146-6200 Changes in puff parameters and smoke constituant uptake (COHb, urinary cotinine) in smokers after switching from medium to low tar cigarettes RADZISZEWSKI E.; SCHILTZ P.; DEBROIS P. CERTSM-DCAN, Toulon-Naval, France Two groups of six blend full flavor cigarette smokers smoked alternately for one week period two kinds of cigarettes specially designed for the study and which differed with respect to their filter ventilation : in one hand, an unventilated one (full...
Bull. ARN, 1990, p. 19-36., ISSN.1146-6200 Critical study of methods for nicotine measurements in environmental tobacco smoke ESQUIER F.; HEE J. CERTSM-DCAN, Toulon-Naval, France The aim of this paper is to critically review the performance of several published methods for the determination of nicotine in environmental tobacco smoke. The efficiency of liquid absorption decreased with increasing sampling duration. The...
Bull. ARN, 1990, p. 10-18., ISSN.1146-6200 Evaluation of an end-expiratory gas sampler. Application to carboxyhemoglobin measurement RADZISZEWSKI E. CERTSM-DCAN, Toulon-Naval, France A simple, cheap, automatic and efficient device has been developed for sampling the end expiratory gas. It consists of two bags connected to a mouth piece via a"T"connector. One branch of this"T"piece has a restriction so that the two bags are filled...
Bull. Spec. CORESTA Symposium, Kallithea, 1990, p. 137, A28, ISSN.0525-6240 Study of the consolidation of haploids derived from anthers and their importance in selection DIMITROVA S.K. Experimental Station Complex, Khan Kroum, Shoumen, Bulgaria. Androgenesis induced in vitro is of increasing importance in the creation of new varieties of tobacco. Equalization and morphological invariability after the doubling of homozygotic genes is of major importance in selection. The culture media for...
Bull. Spec. CORESTA Symposium, Kallithea, 1990, p. 177, P20, ISSN.0525-6240 Study of tomato spotted wilt resistant tobacco lines IANTCHEVA A.M. Complex Experimental Station, Haskovo, Bulgaria. The object of this study was to transfer the TSWV resistance gene from the wild Nicotiana alata species to Oriental tobacco, Nicotiana tabacum, by means of the Line 9693/1. Besides TSWV resistance the breeding material obtained had to possess the...
Bull. Spec. CORESTA Congress, Guangzhou 1988, p. 189, S-15 Methodological problems arising in the control of environmental tobacco smoke HEE J.; GUILLERM R.; ISOARD P.; MALASPINA J-P.; SCHILTZ P. CERTSM-DCAN, Toulon-Naval, France A series of experiments carried out in a climatic chamber under various conditions of confinement, ventilation or of filtration have revealed various difficulties inherent in the characterisation of environmental tobacco smoke. The results obtained...
