A field experiment was conducted to study the effects of fertilizer application rate and number of harvested leaves per plant on selected agronomic, chemical and physical characteristics of burley tobacco(Nicotiana tabacum L. cv Burley 21) in 1988, 1989 and 1990 at Chonju Experiment Station, Korea Ginseng SE Tobacco Research Institute. 175.0 or 227.5 kilogram per 10a of compound fertilizer(N-P2O5-K2O= 10-10-20) were applied as main plot, and 2 or 4 of upper leaves was topped off with 0, 2 or 4 of the lower leaves removed as sub plot. Yield, total alkaloid and total nitrogen content of cured leaves were high in the higher level of compound fertilizer plot, and increasing the level of compound fertilizer had an adverse effect on physical characteristics. Reducing the number of harvested leaves had a negative effect on yield regardless of whether the leaf number was reduced by lower topping or removing the bottom leaves, but increased the rate of higher grades leaves. Differences in total alkaloid, total nitrogen and some physical properties among number of harvested leaf per plant were smaller than expected.

The position of tobacco leaves is affluence to the quality. To evaluate its quality, sample leaves was collected according to the position of attachment. In Korea, the position was divided into four classes such as high, middle, low and inside positioned leaves. Until now, the grade of standard sample was determined by human expert from korea ginseng and tobacco company. Many research were done by the chemical and spectrum analysis using NIR and computer vision. The grade of tobacco leaves mainly classified into 5 grades according to the attached position and its chemical composition. In high and low positioned leaves shows a low level grade under grade 3. Generally, inside and medium positioned leaf has a high level grade. This is the basic research to develop a real time tobacco leaves grading system combined with portable NIR spectrum analysis system. However, this research just deals with position recognition and grading using the color machine vision. The RGB color information was converted to HSI image format and the sample was all investigated using the bundle of tobacco leaves. Quality grade and position recognition was performed through well known general error back propagation neural network. Finally, the relationship about attached leaf position and its grade was analyzed.

This study was performed to investigate the changes in chemical composition of Panax ginseng leaf by harvesting at July, August and September. The levels of crude protein of dried ginseng leaf were decreased from 17.12mg% to 14.26% by harvesting month, however, crude fat contents of dried ginseng leaf were increased slightly from 1.90% to 2.49%. Three kinds of free sugar, i.e. glucose, fructose and sucrose were found in dried ginseng leaf and maltose was not found. Free sugar contents were increased by delaying harvest, but free amino acid were decreased. Total free amino acid was decreased in delayed harvesting month, serine was revealed superior in free amino acid composition, and valine was revealed next order. In minerals, contents of Ca were from 1,306.1mg% to 1,923mg%, that of K were higher than others patricualy as 1,266.9∼1,216.0mg%. The contents of minerals were existence in order of Mg, P, Na, Fe, Mn, Zn and Cu, abundantly. Total vitamin C were present of 391.0∼336.1mg%, and the contents were decreased as delayed as harvesting period despite of the plentiful content. In fatty acid composition of ginseng leaf, the palmitic acid content was as 40% higher than other fatty acids, remarkably.

Three kinds of shading materials, styrol-foam board, pine board and polytex, were examined and compared with ordinary shading, and the effects of light intensity and the temperature under the shadings on the photosynthesis and the root growth of the Korean ginseng were studied to improve the shading on the ginseng field. The amounts of photosynthesis of the ginseng leaves at 2$0^{\circ}C$ were significantly larger than those at 3$0^{\circ}C$ in the same light intensity. At 2$0^{\circ}C$, the maximum photosynthesis occured at 35, 000 lux, but at 3$0^{\circ}C$, the amount of photosynthesis was rapidly reduced by higher light intensity over 26, 200 lux. The best root growth occurred under the polytex shading and the styrol-foam board shading was also effective for ginseng growth. Under the ordinary shading, the root growth of ginseng planted on rear line was very poor but under the styrol-foam or the polytex shading, the root growth showed little difference between the ginsengs planted on rear line and front line.

A particular type of ginseng that grows in mountainous regions of Korea is known as Sansam, a term meaning literally mountain grown ginseng. Sansam has recently gained a reputation among some Korean people who believe its health benefits are superior to that of other types of ginseng. Misuse of Sansam has resulted from misinformation that has circulated about the health benefits of its use. Due to insufficient study and research, Korean Oriental Medicine academia does not presently have enough credible information about Sansam to properly educate the public in its use. However, we do have a responsibility to perform adequate study and research so that correct information may be provided. To date, only cursory investigation of the physical characteristics of the Sansam plant have been conducted. This limited investigation was performed in July 2002, at Sobaek Mountain. The branches, leaves, stems, peduncles, fruits, and roots (head, main and fine roots) were observed. The fine roots grew and spread in a large area around the main roots so that harvesting the plants required digging out the soil a considerable distance from the main roots. The plants grew in a northwesterly direction, with a gradient of 40 degrees. They had four branches. Three of the branches had six leaves, while one had five leaves. Each plant had 40 fruits. The roots of the plants grew in a shape similar the Chinese character for mountain. The roots were milky in color. The average weight of the plants was 42.5 grams.

This Study was conducted to estimate the degree of dominance and gene frequency of some sueful characters in tobacco. The eight parents and a set of 28 crosses of F'1s was F'2s were used as materials, and planted on oriental's and burley cultivated system as randomized block designs, respectively. The observed characters were six agronomic characters which were plant height, number of leaves per plant, leaf length, leaf width, days to flowering and yield, and the data obtained from the experiment were analyzed from methods by Hayman's and Jinks. The results obtained are summarized as follows: 1. In Vr-Wr graphical analysis, number of leaves per plant, leaf length, days to flowering and yield were found to be inherited in partial dominance, and plant height was over dominance to be similar to complete dominance, but leaf width was inherited with partial dominance close to complete dominance. 2. In the gene frequency, two varieties Xanthi-Basma and KA 102, for days to flowering and yield had larger number of dominant genes as those were situated near the point of origen. 3. Additive effects of genes(D) were greater than dominance effects of Genes(H) for six agronomic characters except plant height, and mean degree of dominance over all loci was lower than 1 for days to flowering yield, leaf length and number of leaves per plant.

A CAB cDNA vector(pKGCAB), encoding the light harvesting chlorophyll a/b binding protein in Korean ginseng (Panax ginseng C. A. Meyer), was constructed with the CaMV35S promoter of plant expression vector. The chimeric vector was transformed into tobacco(Nicotiana tabacum cv. NC 82) using Agrobacterium tumefaciens LBA 4404 strain, and the transgenic tobacco plant CAB-TP2 was selected. Photosynthetic rates of the CAB-TP2 plant at before-flowering stage were increased about 20% under low irradiance conditions of quantum 100 and 500 $\mu$mol.m$^{-2}$ s$^{-1}$ , however, the rates were similar to those of NC 82 under quantum 1000 and 2000 $\mu$mol.m$^{-2}$ s$^{-1}$ conditions. The plants were germinating under low- or normal irradiance condition and the quantum yield of photosystem III were measured. The differences of the Fv/Em values between conditions were 0.07 and 0.01 in NC 82 and CAB-TP2, respectively. The mature leaves in the position 8-10 of the CAB-TP2 at before-flowering stage revealed l0% higher Fv/Fm values in range of 0.759 to 0.781 and 40% more chlorophyll contents of 70-93mg/$m\ell$ than those of normal NC 82. These data suggest the possibility that the increase in photosynthetic activity of leaves under low light intensity in the canopy of CAB-TP2 transgenic tobacco might lead to increase the quality of lower tobacco leaves.
