    This study was conducted to find out the relationship among agronomic characteristics including midrib ratio in Burley tobacco(N.tabacum L.) Four cultrivars, Burley 21, KB108, KB111 and KB301, were grown at Suwon Experimental Station in 2001. Several agronomic characteristics of these cultivars were measured for the analysis of correlations among agronomic characteristics. Midrib ratio of KB301 was somewhat higher than those of the other cultivars, but there is no significant differences among cultivars at $5\%$ probability level. Among four stalk positions, midrib ratio of cutters was the highest. Midrib ratio was correlated positively with length of leaf at $1\%$ level and negatively with weight of lamina at $5\%$ level, respectively.

    초록

    During the screening of antiviral substances having inhibitory effects on tobacco mosaic virus (TMV) infection to tobacco plants, we found a bacterial isolate KTGBP10, which was identified as a Stenotrophomonas sp., strongly inhibited the infection of TMV. When the culture filtrate from KTGBP10 was applied on the upper surface of leaves of Xanthi-nc tobacco plants at the same time or 24 hours before TMV inoculation, almost complete inhibition of TMV infection was achieved. And $40\%$ inhibition was shown with application of the culture filtrate to the under surface of leaves. In field trials, transmission of TMV from diseased seedlings to the healthy ones during transplanting work was reduced by $87.1\~92.6\%$ when the culture filtrate or cell suspension was sprayed onto the tobacco seedlings, cv. NC82, 24 hours before transplanting. No toxic effect was observed on the tobacco plants. When the broth filtrate of KTGBP10 was supplied by soaking through the cut-leaves before and/or after virus inoculation, the TMV infection was also inhibited by $50.4\~65.3\%$ .

    This study was conducted to investigate the relationship between weather factors during the growing season and chemical components of burley tobacco. Chemical components used in this study was from 'Farm Leaf Tobacco Test' conducted at KT&G Central Research Institute from 1987 through 2002. Data of weather factors during growing season(April to July) were collected in 6 districts measured at Korea Meteorological Adminstration(KMA). Total nitrogen content was increased from 1987 through 2002. Year to year variation of rainfall was the largest, followed by that of sunshine hour. Month to month variation of rainfall also was the largest, followed by that of mean daily air temperature. A negative correlation was found between rainfall and sunshine hour. Relative humidity(R.H.) was correlated positively with rainfall, whereas negatively with sunshine hour. The negative correlations were found between nicotine content and rainfall(in June, May $\~$ June, June $\~$ July, May $\~$ July and average), and R.H.(in June, May $\~$ June, June $\~$ July, May $\~$ July and average), respectively. The negative correlations were found between crude ash content and rainfall(in June and May $\~$ June), and R.H.(in June, May $\~$ June, June $\~$ July and May $\~$ July), respectively. Ether extraction content was correlated positively with mean daily air temperature(in July, June $\~$ July and May $\~$ July) and with sunshine hour(in July, June $\~$ July and May $\~$ July), but negatively with rainfall(average) and with R.H.(in April, July, June $\~$ July, April $\~$ June, May­July and average), respectively. Chloride content was correlated positively with sunshine hour(in May, April $\~$ May, May $\~$ June, April $\~$ June, May $\~$ July and average), but negatively with rainfall(in June, May $\~$ June, June $\~$ July, April $\~$ June, May $\~$ July and average).

    This study was conducted to investigate the relationship between weather factors during the growing season and chemical components of flue-cured tobacco. Chemical components used in this study was from 'Farm Leaf Tobacco Test' conducted at KT&G Central Research Institute from 1986 through 2003. Data of weather factors during growing season(April to July) were collected in 10 districts measured at Korea Meteorological Adminstration(KMA). Nicotine and total sugar contents, and total sugar to nicotine(TS/Nic.) ratio were increased, whereas total nitrogen to nicotine(TN/Nic.) ratio and chloride content were decreased from 1986 through 2003. Year to year variation of rainfall was the largest, followed by that of sunshine hour. Month to month variation of rainfall also was the largest, followed by that of mean daily air temperature(MDAT). Rainfall was correlated positively with relative humidity(RH), but negatively with sunshine hour. Nicotine content was correlated positively with MDAT(in July, June $\~$ July, May $\~$ July and average), but negatively with rainfall(in May $\~$ July) and with RH(in June, July, May $\~$ June, June $\~$ July, April $\~$ June, May $\~$ July and average). Total sugar content was correlated positively with MDAT(in May), but negatively with sunshine hour(average) and RH(in June, July, June $\~$ July, April $\~$ June, May $\~$ July and average). The positive correlation was found between total nitrogen content and sunshine hour(in April, May, April $\~$ May, May $\~$ July, April $\~$ June and average). The negative correlation was found between TS/Nic. ratio and sunshine hour(in May $\~$ July and average). TN/Nic. ratio was correlated positively with sunshine hour(in May and April $\~$ May) and with RH(in July and June $\~$ July), but negatively with MDAT(in July, June $\~$ July, May $\~$ July and average). Ether extraction content was correlated positively with MDAT(in July, June $\~$ July, May $\~$ July and average) and with sunshine hour(in July and June $\~$ July), but negatively with rainfall(in April, July, May­July and average).

    The present study was carried out to compare the composition of major essential oil components in the flue-cured tobacco produced by Korea, America, China, Brazil and Zimbabwe. Above 100 essential oil components were separated by GC and major 18 components of them, known to be important contributors to flue-cured tobacco flavor and smoke taste, were identified by GC/MS. Neophytadiene was major in quantities in the oils mostly and its composition in flue-cured tobacco produced by Korea, America, Zimbabwe, Brazil, and Unnam and Yenji region of China was 26.82\%,\;25.17\%,\;26.50\%,\;16.92\%,\;and\;18.75\%\;and\;14.87\%$ , respectively. Megastigmatrienone, one of the major tobacco carotenoid degradation products was contained above $10\%$ in the oils of flue-cured tobacco produced by Korea and America, but, it was comprised about $5.66\%$ to 8.00 in Brazil, Zimbabwe, and Unnam and Yenji region of China. Damascenone is important to the aroma of tobacco as a crotenoid degradation products. Its amount in the oils was $3.31\%\;in\;Brazil,\;3.13\%\;in\;America,\;2.57\%\;in\;Zimbabwe,\;2.54%$ in Yenji of China, $2.00\%$ in Korea and $1.85\%$ in Unnam of China. These results can furnish the basic information capable of evaluating the quality value of flue-cured tobacco produced by various nations.

    This study was conducted to investigate the composition of flavor components of Elsholtzia ciliata and Eisholtzia splendens in order to obtain basic informations for the application of tobacco and food industry. Flavor components extracted were divided into three fractions ; essential oil, absolute and oleoresin from E. ciliata and E. splendens. Essential oil was extracted by simultaneous steam distillation(SDE), absolute and oleoresin were extracted by $100\%$ n-hexane and $50\%$ ethanol, respectively. Yields of the essential oil, absolute and oleoresin fractions from E. ciliata were $0.34\%,\;11.34\%\;and\;15.24\%,$ and those from E. splendends were $0.28\%,\;12.45\%\;and\;9.95\%$ , respectively. The major components of essential oil of E. ciliata were naginata ketone $(29.37\%)$ , elsholtzia ketone $(14.37\%)$ and rosefuran $(11.76\%)$ . The major components of essential oil of E. splendens were 2-cyclohexen-1-one $(26.81\%)$ , elsholtzia ketone $(13.46\%)$ and naginata ketone $(5.26\%).$ The composition of flavor components showed a slight difference between essential oils of E. ciliata and E. splendens. The major components of absolute fraction from E. ciliata were linoleic acid $(12.07\%),$ palmitic acid $(10.46\%)$ and 2-cyclohexene-1-one $(5.39\%).$ And those from E. splendens were linoleic acid $(12.38\%),$ palmitic acid $(9.47\%)$ and naginata ketone $(8.86\%).$ Ethyl linoleolate was a major component in oleoresin of E. ciliata and E. splendens.

    In this study, we have investigated the natural and puffing combustibility of cigarette brands and the compulsory ash-drop, and analysed factors related to the materials. Cigarette combustibility was greatly affected by the tobacco weight in cigarettes rod. Combustion rate of 4AOR cigarette made by flue-cured tobacco was 5.02 $^{mm}/_{min}\;and\;10\%$ faster than 1BO cigarette. Combustion pattern has interrelation with sugars, chlorine and ash contents among tobacco components. Combustion rate of 4DL, flue-cured tobacco was 55 seconds faster than 1CL tobacco extremely much in sugars contents, and ash drop was maintained at $21\%$ longer. Combustion time and burning rate were fast in cigarette made by expanded tobacco slice and tobacco stem and the formation of ash was poor. The length of puffed ash drop of expanded tobacco slice and tobacco stem were 18.6 mm and 25.2 mm and these forced ash drop length were 3.8 mm and 4.9 mm respectively. Puffed burning rate of general cigarette was $14.3\%$ faster than static burning rate and super slim type cigarettes was $21.3\%$ faster. Combustion rate and ash drop of domestic and foreign cigarette brands were quite different depending on tar level and cigarette types. The lower tar level, the faster combustion rate and the shorter ash drop.

    Tobacco dust samples were collected for two times in primary and secondary process at 4 cigarette manufacturing factories(Shintanzin, Youngju, Wonju, Kwangju) and analyzed to evaluate usage as a raw material in production of reconstituted tobacco. The chemical constituents and HWS of tobacco dust were analyzed. Tobacco dust samples were partitioned by particle size using a series of screens ranging from 20 to 200 mesh. The amount of material retained in each fraction was quantified and sand content was also determined. Appreciable average amounts $(40-65\%)$ material at 4 locations were found to be larger than 60 mesh. Although the amount of material in each fraction increased to a maximum at 100 mesh and then decreased, the $\%$ sand continually increased with decreasing particle size. The chemical constituents and HWS content of tobacco dust have similar values in secondary process of 4 cigarette manufacturing factories but the those of primary process have different values according to the site of occurrence and manufacturing factories.

    To evaluate utilization of tobacco dust as a raw material of reconstituted tobacco, tobacco dust was applied to the paper-making reconstituted tobacco process and we examined the chemical and physical properties of the reconstituted tobacco and raw materials. The use of tobacco dust in the manufacture of reconstituted tobacco had no measurable adverse effects on the chemical properties of the reconstituted tobacco when added to the reconstituted tobacco formula at levels of $3\%,\;5\%,\;7\%\;and\;10\%$ instead of foreign bright stem. Filling power and fragibility index of the reconstituted tobacco was slightly decreased with increasing tobacco dust levels, but it was not significant change. However, when the level of $10\%$ tobacco dust was added to the reconstituted tobacco formula, the tensile index based basis weight was rapidly decreased.

    This study was conducted to evaluate the characterization of the pyrolysis products of tobacco constituents such as cellulose, lignin and tobacco additives. The pyrolysis condition was designed to simulate the pyrolysis/distillation zone $(200\~600^{\circ}C)$ and combustion zone $(700\~950^{\circ}C)$ of burning com in the smoking cigarette. The pyrolysis products were determined by GC/MS after pyrolysis using Double-Shot pyrolyzer. In the case of cellulose and lignin, the number of pyrolysis product in the condition that simulate the pyrolysis/distillation zone was much more than the combustion zone simulating one. The major products of cellulose were levoglucosan, furfural, and 1, 6-anhydro- $\beta$ -D-glucofuranose and that of lignin were phenol, 2-methoxy phenol, and 1, 2-dimethoxy benzene. In the case of tobacco additives such as 2, 6-dimethyl pyrazine, maltol, and piperonal, the pyrolysis products of these additives were evaporated from the pyrolyszer at least $96\%$ intactly. These results indicate that tobacco constituents such as cellulose and lignin were thermally degraded at the pyrolysis/distillation zone and thoroughly broke down at the combustion zone, but tobacco additives were intactly evaporated from burning com of smoking cigarette.
