This experiment was carried out in order to study the effects of shading and girdling respectively, through the late stages of growth, on the yield and accumulation of chemical components of tobacco plants. Shading treatment continued from June 9th until harvesting with Hicks tobacco transplanted in the 1/2000-a-pot on April 28th, 1971. And girdling treatment was conducted on June 12th, and then its tobacco was cultured under the same condition with control plots. The tobaccos in all plots were arragned 11 leaves per plant at the time of topping. All of the leaves of each treatment were harvested at the time on july 9th, and the effects of each treatment were investigated. The summary of the results are as follows; 1.Stem height of each treatment plot was somewhat higher than the control plot, and highest in the shading plot with double sheets of victoria lawn. The dry weight and ration of dry matter of stem were greatly decreased by shading with double sheets of victoria lawn, but showed an increasing trend by girdling treatment. 2.There were no differences in the dry weight and ration of dry matter of the leaves between girdling treatment and control. But dry weight and ratio dry matter were greatly decreased in the case of shading with double sheets of victoria lawn. 3.Leaf size was slightly increased by shading treatment, though it was the same with control in girdling treatment. 4.Number of dried-up leaves was 1.0 leaf in control, 0.3 leaf in shading and 0.5 leaf in girdling treatment. 5.The content of total alkaloid was slightly decreased by shading treatment, and considerably decreased by about 1.0% as a result of girdling treatment. 6.The content of protein-N was higher especially in upper leaves of shading treatment tobacco, but somewhat lower in girdling treatment tobacco. 7.For the carbohydrates, the content of insoluble sugar was not of any considerable difference among each plot. However the content of soluble sugar was greatly decreased in the shading plot, and tended to decrease as the intensity of sunshine was getting weak. On the contrary the content of soluble sugar was remarkably increased in girdling plot. 8.The ratio of soluble sugar against total alkaloid was very low in the shading plot in comparion with the control, and depending on the intensity of sunshine, its ratio was lowered remarkably. While the ratio was considerably higher in the girdling plot in terms of quality. 9.As a result of this experiment, it can be seen that growth and accumulation of chemical components was not good by shading treatment through the late stages of growth of tobacco plants, but very much improved in terms of good quality through girdling treatment.

This experiment was conducted to investigate the effect of K2O on the water cultured tobacco plants in a green house. In the case of different condition of nitrogen, iron and environment, the effects of different levels and periods of treating time of K2O on the growth, development, dry matter production, yield and quality (chemical components ) were studied. 1.The higher the level of K2O was, the larger the dry matter production and growth were. The differences of these were significantly large in the high level of nitrogen, but not significant in the low level of nitrogen. 2.The flowering and maturing were remakably accelerated by the increased K2O supply under the condition of low temperature and short day, but they were not accelerated under high temperature and long day. At the low (deficient) level of nitrogen, the increased K2O supply delayed flowering. 3.The number of differentiated leaves showed little difference among the plots of different K2O levels, but it decreased at the low level of K2O and nitrogen. 4.The yield increased rapidly as the amount of K2O increased until 80ppm under the condition of low temperature and short day, however there was little difference among 80, 160 and 320ppm of K2O. On the other hand the yield increased until 200ppm of K2O supply under the condition of high temperature and long day. The effect of increased K2O supply on the yield was enhanced by the increased nitrogen supply. 5.The dry weight of the root was increased with the increased K2O supply and this effect was enhanced by the high nitrogen level. T/R ratio was decreased significantly by the increased K2O supply. 6.The more the K2O supply was, the higher the content of soluble sugar and K2O in the leaves were, and the lower the total nitrogen was. The content of nicotine in the leaves was low in the low level of K2O (0,8 and 10ppm), but that showed little difference among the plots of standard (80ppm) and high (150, 200ppm) levels of K2O. Ash content showed little difference among the plots of different levels of K2O. 7.There was positive correlation between the content of soluble sugar and K2O in the leaves, and negative correlation between the content of nicotine and K2O in the leaves. 8.It was concluded that the effect of K2O supply on tobacco Plants were changeable in accordance with the environmental condition of cultivation.

Plant growth regulators such as kinetic, gibberellin, TIBA and B9 were treated to Hicks tobacco (Nicotina) Tabacum L.) at the early stage of growth, and it was investigated that effects of the regulators on growth and development of tobacco plants and chemical components of curable leaves. Kinetin; Early growth of tobacco plants was accelerated and dry weights of curable leaves and stem increased in kinetin 5ppm plot. Soluble carbohydrate in the curable loaves increased, while nicotine and total nitrogen decreased by kinetin treatment. Gibberellin; Early growth was accelerated even in low gibberellin levels (4-8ppm), but dry weight of curable leaves and stem was reduced. This reduction was due to growth inhibition by gibberellin which made the growing tissues lignified. TIBA and B9; There is no important effects of TIBA and B9 on growth and weight of dry matter, but quality of curable leaves was reduced by TIBA and B9 treatment. Every hormone had little effects on developmental phase such as number of total leaves, differentiation of flower bud and flowering. Interaction among the hormones; Compound treatment of kinetin + B9 decreased remarkably the yield and growth of the top, and the stem height increased by compound treatment of kinetin + TIBA and kinetin + gibberellin. Fresh weight of a plant and leaf width decreased significantly by compound treatment of gibberellin + TIBA and gibberellin + B9.

This experiment was carried out in order to study the factorable period of girdling for imperovement of the yield and the quality of tobacco leaves. Hicks tobacco was transplanted on the 1/1000-a-pot and cultured all period of growth in a green house. Girdling was conducted at three different stages of growth; 10 days before topping, same day with topping, 10 days after topping, and a nontreatment plot (control plot) were set up. The tobaccos in all plots were arranged 12 leaves per plant at the same time with topping, and the leaves of each plot were harvested at the same time according to the leaf position and used for investigation and chemical analysis. 1.There were no different appearance in growth characters of each plot, but dry weight of stems in all girdling plots were greatly increased in comparison with the control plot. 2.Leaf area of the harvested leaves was not different in all plots, but dry weight of the leaves in each girdling plot showed a tendency of increasing in contrast with the control plot. 3.There were no differences in leaf thickness among all plots, but the proportion of midrib was decreased slightly in the two earlier girdling plots. 4.The alkaloid content of harvested leaves was considerably decreased by girdling, and tended to decrease remarkably as the girdling time was getting earlier and leaf position was getting upper. 6.The ratio of soluble carbohydrate to total alkaloid were increased in all the girdling plots and showed a tendency of increasing as the girdling time was getting earlier, especially in the middle leaf and upper leaf at a certain girdling time. 7.As the result of this experiment, it is found that girdling has the remarkable effects on the improvement of quality but not much on quantity, and that the favorable time of girdling is during the 10 days before topping.

This experiment was conducted to study the effects of gibberellin and ethrel treatment on the root growth of Hicks tobacco seedlings. The number of secondary root emerged in 15 days after gibberellin treatment decreased in the gibberellin 50, 100 and 200ppm plots, and the higher gibberellin content was, the greater the decrease was. Elongation of secondary root was effected by gibberellin treatment as same tendency as the number of secondary roots. The number of secodary root decreased also in 500 dilution of ethrel plot, but increased slightly in 2000-4000 dilution of ethrel plots. Elongation of secondary root was inhibited markedly in each ethrel treatment plot, and the higher ethrel content was, the more elongation of the root inhibited extremely.

The experiment was conducted to investigate the effect of kinetin treatment on growth and development of tabacco plants. Experiment plots were composed of 5 kinetin levels (0, 5, 10. 25 and 50ppm), and the kinetin was sprayed at cotyledons after germination of tobacco seeds 5 times everyday. For thin experiment. Hicks tobacco(Nicotiana Tabacum L.) was cultured in field condition after the kinetin treatment. Stem elongation was accelerated in only 5ppm plot, but final stem height was higher in all treated plot than control plot, especially in 5 and 10ppm plots. Fresh and dry weight of shoot (stem, leaves) were increased at all stages of growth in kinetic treated plots, and there were remarkable differences in low kinetin levels and at late stage of growth. There was no measurable differences on number of differentiated leaves, days to flowering, curable leaves, leaf area and leaf shape between each plots. But fresh and duty weight of curable leaves were increased significantly in 5 and 10ppm plots, and stem weight and diameter showed the name tendency to the weight of curable leaves. And no change was showed in nicotine and total nitrogen contents among curable leaves by kinetin in treatment.

이상각,강병화,배길관 高麗大學校 自然資源科學硏究所 1998 自然資源科學硏究 Vol.6 No.-

Korean Ginseng (Panax ginseng C. A. Meyer), herbaceous perennial of family member of Araliaceae, has been a main subject to elucidate its medicinal efficacy for a long time. As a result, the basis of scientific theory on the medicinal efficacy has been addressed. In the summary of the introduced book "Ginseng", the applicaiton of well-rotted horse manure can be a potential adventage for its growth. The edibility of berry also widen its potential as a good matenial for food proessing. It is highly feasible to produce beverage or pickled berry with ginseng fruits. In America, as early as 1890, optimal growth condition was determined with well-defined experiment and observatin. They reported that four to six years is long enough to keep transplanted roots in the ground. IN comparison the cultivatin of this valuable roots had been established before the time in Korea peninsula, especially in the neighborhood of Kaisong. According to old chinese trading report (1896), the price of Korean ginseng was $16.50 per pound which was nearly nine times high than the price of ginseng from America, priced at $1.86 per pound. The detemination of ginseng price did not followed the general law of supply and demand. It depends upon the color, the form and size, and its fancied resemblance to the human body. In Korea the cultivated ginseng is smaller than wild type or sansam(mountain sinseng) in length and diameter. The medicinal efficacy of samsam is belived to involve many physical rejuvenation such as improvement of physical strength and recovery from sleeplessness and many diseases. All these cure seems to come from improved immune system. That is why many people call ginseng as a miraculous elixir.

This experiment was performed to investigate and to analyse the effects of sail moisture condition on growth, yields and content of nicotine and to study the adaptability to environment of oriental tobacco. 15 varieties (Samson Xanthi etc.) of oriental tobacco were applied in this experiment. Three levels of soil moisture condition were 30% (Damp) 45% (Moist), and 60% (Wet) to the maximum water holding capacity. The results obtained are summarized as follows. 1.The number of harvested leaves was high in order Samsun〈 Basma〈 Xanthi Gaya〈 Bursa〈 Izmir and low in order Zichna 〉Samsun Holmus 〉Xanthi 〉Smyrna. But there were little differences among the treatments. 2.Percentage of dried up leaves showed no differences among the treatments. Among the varieties, it showed inverse proportion to the tendency of number of total leaves. 3.Leaf area had a tendency of Damp〈 Moist〈 Wet and showed significant difference between the plot of Damp and the plots of Moist and Wet. Among the varieties, Zichna and Mahola had remarkably broad leaves, Bursa, Nigrita, Smyrna, Xanthi and Drama etc. had narrow leaves, and the other varieties Showed no differences. 4.Dry weight of unit leaf area was low at the plot of Damp, and high at the plots of Moist and Wet. Among the varieties, that was appeared in order Baschibaglis〈 Xanthi〈 Nigrita〈 Smyrna. Xanthi Gaya, Zichna, Mahola and Samsun Holmus had light weight of unit leaf area. 5.There were significant differences on yieldg among treatments in order Damp〈 Moist〈 Wet. Especially, high significant differences of yields were appeared between the plot of Damp and the plots of Moist and Wet. Among the varieties, yields was high in order Izmir〈 Basma〈 Smyrna〈 Baschibaglis〈 Mahola and low in order Nigrita 〉Bafra 〉Samsun Holmes 〉Xanthi. Every variety has his own type of constitution of yields. 6.The content of nicotine was low in order Bursa 〉Mahola 〉Izmir 〉Basma 〉Samsun 〉Drama and those of these varieties were under 1.8%. And that was high in order Xanthi〈 Zichna〈 Samsun Holmus〈 Bafra〈 Nigrita〈 Xanthi Gaya〈 Smyrna, and those of these varieties were about 2.0∼3.8%. Among treatments, the plot of Damp had a tendency of low content of nicotine.
