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 carried omit in order to investigate the most effective methed of girdling for improvement of tobacco quality and saving of labour and time. Hicks tobacco was cultured in 1/1,000-a-pot in a green house. Girdling was treated by H2SO4, NaOH, K2SO4 and cut with a knife at the flowering time, and a non treatment plot (control) was set up. The tobaccos in all plots were limited to 15 leaves per a plant concurrently with topping, and the leaves of each plot were harvested simultaneously according to leaf position and used for investigation and chemical analysis. 1) The visible effect of girdling was good in H2SO4 and NaOH plots, while calluses partly developed in the treated position of K2SO4 and knifed areas. 2) Leaf area was the same in all plots, but dry weight per leaf and unit area of the leaves tended to increase in H2SO4 and NaOH plots, especially in the H2SO4 plot. 3) The alkaloid and total nitrogen contents of the harvested leaves were significantly decreased in H2SO4 and NaOH plots in comparison with the control plot, and tended to decrease in the K2SO4 and knifed plots. 4) Soluble carbohydrate content showed an opposite tendency to alkaloid. 5) The radio of soluble carbohydrate to alkaloid was remarkably increased in the following order: H2SO4>NaOH>knife> K2SO4 in comparison with the control. 6) As a result of this experiment, it is found that girdling by H2SO4 and NaOH has a significant effect in both sensus of the improvement of tobacco quality and the saving of labour and time.

煙草植物의 生理, 生態에 關한 硏究 : 第一報 培養液中의 K₂O濃度가 煙草植物의 生長 및 發育生理에 미치는 影響 I. Physiological Effects of K₂O Concentration in Culture Solution on Growth and Differentiation of Tobacco Plants

裵吉寬,盧載榮 충북대학교 엽연초연구소 1977 煙草硏究 Vol.4 No.-

The experiment was conducted in order to investigate the influence of K2O levels on growth and differentiation of tobacco plants. Experiment plots were comported of 6 K2O levels (0, 8, 40, 80, 160 and 320ppm) which consisted of 3 different periods of treatment (whole growing period (I), secondary bed period (II), and field period (III). For this study, Bright Yellow tobacco (Nicotiana Tobacum L) was cultured by a renewal water culture system in a green house. 1.Stem elongation was accelerated in accordance with increasing K2O levels, especially in the early stage, and the effect was most significant in block I. 2.The increase of visible leaves showed the same tendency to stem elongation, but the total number of differentiated leaves were not different between each plots. 3.Days to flowering were significantly reduced according to the increase of K2O levels in block I and II, expecially block I. However there was no difference in block III. 4.The dry weight of harvested leaves was significantly increased from 0 ppm to 80 ppm in block I, while it was increase to 320ppm in block II and III. 5.The higher the K2O concentration, the lower the T/R ratio was. This was especially remarkable in block I. Roots continued to grow more than stems and leaves in higher K2O levels (160 and 320 ppm). 6.When K2O was administered in culture solution of from 0 ppm to 80 ppm the alkaloid content increased. However, there was no alkaloid increase when K2O solution of from 80 ppm to 320 ppm wer administered. 7.Conversely, the total nitrogen content followed the opposite tendency to decrease with the rise of the alkaloid content. 8.Soluble carbohydrate content was not regularly changed in accordance with the increase of K2O levels.

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.

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.

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.
