This experiment was conducted to investigate the effect of Ca and Cl concentration in water culture solution on the growth and yield of free-cured tobacco. Results of Ca treatment ; 1.Dry weight of harvested leaves was largest in Ca 150 ppm plot. 2.Leaf growth was inhibited, and the length/width ratio of leaf was large in Ca 0 ppm plot. 3.Root growth was much inhibited and so T/R ratio was increased in Ca O ppm plot. Result of Cl treatment ; 4.Stem height and leaf area were largest in Cl 100 ppm plot, and leaf shape was not influenced in accordance with Cl concentration in culture solution. 5.Dry weight of harvested leaves was increased with the increases of Cl concentration (12.5, 25, 50, 100ppm) in culture solution but the weight in the plot of 200ppm of Cl was smaller than those in 50 and 100ppm of Cl. 6.Differences of dry weight of stem and root skewed the same tendency as that of dry weight of leaf. 7.T/R ratio was highest in Cl 200 ppm plot.

Effects of auxin and Rootone on the rooting of Juniperus chinensis var. Kaizuka cutting were investigated to improve propagation efficiency. When Rootone treated, rooting was 100% compared with the control, 33%. IBA 200ppm 1h and NAA 100ppm 12h improved evidently rooting, 93% and 90%, respectively. Root fresh weight increased up to 131mg by Rootone. NAA 200ppm 12h, NAA 500ppm 1h, and IBA 200ppm 1h were also very effective to root fresh weight more than 110mg. Shoot growth(height, fresh weight and dry weight) did not increase largely, but increased a little. Dipping into high concentration auxin solution for 1min increased rooting rate and root fresh weight, but was less effective than low concentration treatment. Shoot growth did not increase largely, but increased a little. These results indicate that Rootone and IBA 200ppm 1h are most effective for improvement of rooting in Juniperus chinensis var. Kaizuka cutting.

자화수와 파이워터는 분자구조가 매우 작은 물로, 생체에 흡수가 잘되고 내병성이 증가되며 절화의 수명과 품질도 크게 증진시킨다고 알려져 있다. 본 실험에서는 이들 물을 이용하여 장미와 카네이션의 절화수명과 품질에 어떤 효과가 있는지 조사하였다. 장미에서 파이워터(N)은 수도수 보다 물의 흡수가 더 잘되어 꽃잎 전개를 촉진시키는 경향이 보였으나, 자화수나 파이워터(W)는 오히려 꽃잎전개를 억제하는 것으로 나타났다. 또한 파이워터(N)만 절화수명을 대조구(수도수) 보다 1일 정도 연장시키는 경향이 있었을 뿐, 다른 물에서는 효과가 보이지 않았다. 카네이션에서는 꽃잎 전개 정도나 수분 흡수에서 처리간 차이가 거의 보이지 않았다. 다만, 파이워터(N)와 자화수가 절화수명을 1일 정도 연장시키는 것으로 나타났다. 자화수와 파이워터의 이화학적 특성을 조사한 결과, 모든 물의 pH는 7.1에서 7.3 범위에 속해서 큰 차이를 보이지 않았으며, ORP도 212mV에서 242mV 범위로 물의 종류간 큰 차이를 보이지 않았다. 용존산소는 파이워터(N)에서 6.2mg/L로 수도수 9.4mg/L 보다 낮았으며 자화수와 파이워터(W)는 수도수와 비슷한 정도였다. 따라서 본 실험에서 자화수와 파이워터가 절화수명 연장에 뚜렷한 효과가 보이지 않았던 이유가 본 실험에 사용된 자화수와 파이워터가 본래의 성질을 가지지 못했을 가능성이 크다고 판단되었다. Magnetized water and Pi water which are very small in molecular size, are very easy to be absorbed into plant, improve the resistance against diseases and extend the vase life of flowers. This study was conducted to clarify the effect of these waters on the vase life of rose and carnation. Pi-water(N) was absorbed more than tap water and stimulated the opening of rose flower. However, magnetized water and Pi-water(W) inhibited the opening of rose petal. Pi-water extended the vase life of rose by only 1 day, but other water did not. Effect of magnetized water and Pi-water on the opening of flowers and evaporation and transpiration amount in cut carnations were not observed. Pi-water(N) extended the vase life of carnation flowers by 1 day, but other water did not. pH of all kinds of water studied in this study were the range of 7.1 to 7.3. ORP of these water were the range of 212mV to 242mV. DO of Pi-water(N) was 6.2mg/L, lower than 9.4mg/L of tap water. DO of magnitized water and Pi-water(W) were similar to that of tap water.

One of the most important problem during summer plug plant production is the succulent growth. The possibility of controlling height of plug seedlings by temperature drop shock(TDS) was investigated in Pharbitis, Impatiens and Callistephus. The most sensitive plant to TDS was Pharbitis. By 2℃ water irrigation, height of Pharbitis decreased by 33%. Impatiens showed 16% reduction in height by 2℃ water irrigation. Callistephus showed no reduction in height by any treamtnet. In all plants, stem diameter increased about 10% by the cold water irrigation. Leaf injury such as leaf spot of Saintpaulia was not observed. These results suggested that TDS could be used for controlling height of summer plug seedlings such Pharbitis which is sensitive to TDS.

This experiment was carried out to study the influence of different sowing time, seedling age (the degree of delayed setting) and seedlingbed materials on the growth and yield components of flue-cured tobacco. The variety applied was N.C. 2326, was sown on March 1,11,21 and 31. Those plants were transplanted on the seeding bed mixed humus with sand at the ratio of humus 9 : sand 1 and humus 3: sand 7, 25 days after sowing. Seedlings were grown for 40, 50, 60 and 70 days (from sowing to setting) on the seed bed and seedling bed, and set on the pots (1/5,000a) in the vinyl house. The results obtained were as forlows . 1.The amount of growth of seedlings increased by late sowing and delayed setting. 2.Until the time before the maximum growth stage after setting, stem heigth was larger in the plots of late sowing and delayed setting. After the middle part of maximum growth stage, the earner the sewing time was, the more remarkable the influence of seedling age on the stem elongation was and the larder the seedling age was, the more remarkable the influence of sowing time on the stem elongation was. 3.Stem diameter was large in the plot to late sowing until the early part of maximum growth stage but after the middle part of maximum growth stage the diameter was large in the plants sown at March 11 and March 21. 4.The number of leaves per plant increased by late sowing and delayed setting shown significant difference after maximum growth stage. 5.Late setting made the stem height high and number of leaves per plant more. The size of largest leaf was small in the plot of early sowing and large in the plot set after May 10. 6.It takes more days to reach a topping time from sowing and setting in the case of early sowing and early setting. 7.In early sowing plots, the leaf area of lugs and cutlers decreased by younger seedling age, and in late sowing plots, that decreased by older seedling age. The leaf area of leaf and tip at different treatments showed similar results, but in the plots sown at March 11 and 21, largest leaf was shown in the plot of 50- day seedlings. The area of green tip decreased by late seeding and delayed setting. As a result of theses the plant type showed sylindrical in the plot of early sowing and younger seedling age, and cone shape in the plot of late sewing and older seedling age. 8.The earlier the sowing time and the younger the seedling age were, the heavier the weight of unit leaf area of lugs and cutters, but there were little influences of different sowing time and seedling age on the weight of unit leaf area of leaf, tip and green tip. The percentage of dry matter showed similar tendency to the results of weight of unit leaf area. 9.Late sowing (March, 31) decreases the weight of a cured leaf. Weight of cured cutter was largest in the plots sowing March 1 and that of leaf tip and green tip was largest in the plots sowing March 11 and March 21. The weight of cured lugs was largest in 40 and 50-day seedlings, and that of tip and green tip was largest in 50-day seedlings. There were little differences of weight of a cutter and leaf among the treatments of different seedling age. 10.In 40- day seedlings, the area and weight of leaves per plant increased by late sowing, and in 70-day seedlings, those increased by early sowing. In 50 and 60-day seedlings, those were highest in the plots sown at March 11 and March 21. Largest weight and area of leaves per plant was shown in the plot set on May 10, and the plots set on April 10, and June 1 showed significantly low weight of loaves per plant. 11.Late sowing and older seedling age increased the leaf thickness of those leaves. Different sowing time and the seedling age did not influence on the leaf area contraction ratio and leaf thickness of leaf, tip and green tip. 12.There were significantly negative correlation between leaf area of lug and cutter and weight per unit leaf area, percentage of dry matter and leaf thickness of the lug and cutters, but no correlation between those characters of leaf, tip and green tip. Weight per unit leaf area correlated positively with percentage of dry matter and specific leaf weight in all stalk position. In the lug and cutter, weight per unit leaf area correlated positively with leaf thickness and negatively with leaf area contraction between weight per unit leaf area and leaf area contraction ratio. There were negative correlation between leaf thickness and leaf area contractions of lugs and cutters, and no correlation between those characters of leaf, tip and green tip. 13.There were not significant effects of seedling bed materials applied in this experiment on the growth after setting and yield components.

Survey for utilization, future availability and demand prospect of 32 cut flowers on 120 flower shop owners was conducted. On the utilization for purposes, out of 32 cut flowers surveyed, cut flowers evaluated as more than 'good' were 15, 14 and 12, in for flower basket, bouquet and home, respectively. Flowers evaluated as less than 'medium' were just 1-2 kinds including standard chrysanthemum. For event decoration and religion, 5 and 8 cut flowers were evaluated as more than 'good'. For consolation garland, celebration garland and bridal bouquet, just 1, 6 and 7 plants were evaluated as more than 'good'. These results indicated that utilization of cut flowers were largely different according to their use purposes. On the future availability, all 32 cut flowers were evaluated as more than 'good' in for religion. Almost plants were evaluated as more than 'medium' excepting standard mum and gerbera in for home, standard mum and china aster in for celebration garland, standard mum in for flower arrangement, houquet, flower basket and event ceremony. However, for consolation garland, just 7 plants including standard mum were evaluated as more than 'medium'. For bridal bouquet, just 5 plants including rose were evaluated as more then 'good'. The importance for purposes of cut flowers is orderly for flower basket > bouquet > celebration garland > consolation garland > bridal bouquet > flower arrangement > event decoration. The demand prospect for purposes of cut flowers was evaluated as more than high in for flower basket and bouquet, as more than medium in for event decoration, home, flower arrangement and religion, and as less than medium in for celebration garland.

장충근,송재용,이기선,강준길,김수용 충남대학교 1990 忠南科學硏究誌 Vol.17 No.2

Thin tantalum pentoxide(Ta_2O_5) films were deposited by oxygenassisted pyrolysis of tantalum methoxide using LPCVD method and their UV-absorption characteristics, X-ray diffraction, surface structure and I - V characteristics were investigated. Ta_2O_5 films as grown were originally amorphous and became polycrystalline hexagonal δ-Ta_2O_5 after annealing at 800℃ in the nitrogen gas atmosphere for 4 hours. The structures of the si_3N_4 films deposited by LPCVD were basically amorphous but mixed micro crystallites were observed in the films. For the Ta_2O_5 films of about 1000Å thick, the leakage current density through the films was 10 exp (-7) A/㎠ at 5 MV/㎝. The leakage current density was high and breakdown voltage was low with respect to Si_3N_4, Ta_2O_5 films could make them attractive in multiplayer dielectric thin films for memory devices.
