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.

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.

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 加里營養에 관한 硏究

裴吉寬 충북대학교 엽연초연구소 1980 煙草硏究 Vol.7 No.-

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.
