Paclobutrazol 이 盆植 石蒜(Lycoris radiata Herb)의 開花와 生長에 미치는 影響
이동훈,김동철,허북구,정은정 順天大學校 農業科學硏究所 1993 農業科學硏究 Vol.7 No.-
The effects of concentration, time, and method of paclobutrazol treatment on the flowering and growth of potted Lycoris radiata were investigated. The treatment method, dipping and spray has no effects on the flowering and growth. Soil drenching only about one month before the flower initiationis affecting the flowering and growth; and 25 ㎎ ai/pot proves to be effective. The size of flower, flower longevity, and the number of the florets does not show any noticeable change, irrespective of the difference in the concentration, time, and method of paclobutrazol treatment. The tissue of flower stem treated with paclobutrazol as a retardant has smaller and denser stoma than that of untreated flower stem.

This study was designed to investigate the changes trends of types, materials and vessels in the modern flower arrangements. The data were obtained from sampled 842 oriental style works from 1971 to 1990 years. Flower arrangement types were decreased 12% in the ratios of the straight, slant and drooping types in 1989-1990, compared to those of 1971, but free type was increased 15% at the same period. The line method, among expression technics of flower arrangements was 56.1%, but the tendency was gradually decreased. Numbers of materials used in oriental flower arrangements were increased 17 in 1971, 20 in 1983-1984 and 22 in 1989-1990, respectively. Combination ratio was increased in order of cut flowers, ornamental foliages, woody plant and others. Number of material sort per flower arrangement was increased 2.6-4.0 in 1989-1990, compared to those of 1971. Utilization frequencys of flower arrangements were increased in chrysanthemum and rose. Utilization of plant material per flower arrangement was increased in order of cut flowers, ornamental foliages, woody plants and orthers, but ornamental foliage was particularly increased in summer, and woody plant was used greater in autumm and winter. Sort and form of flower vessels were more various and numerous in 1989-1990, than those to in 1971.

This experiments were carried out to find out applied methods of plant growth retardant on the growth and flowering of Lilium cvs (Casablanca and Connecticut King). In coating application of ancymidol, PP333 and uniconazole, flowering rate was high(92-100%) at the low concentration(0.05-0.1㎎/bulb) in Connecticut King. Soil drenching and dipping of uniconazole at the same concentration reduced flowering rate of Connecticut King. Normal flowering rate by coating application of ancymidol and PP333 was decreased by high concentration levels or soil drenching. Flowering was normal at the coating application, but somewhat delayed by soil drenching in Connecticut King compared to the control. Flowering date in Casablanca showed no differences among treatments. Plant stem elongation was retarded by coating application of each retardant in Connecticut King and Casablanca. Leaf growth was somewhat different among treatments, and flower quality had net significant change. Activity of GA-like substances(R.f 0.4) was decreased, but activity of ABA-like substances(R.f 0.8) was high after administration of PP333 and uniconazole. So it is found out that PP333 and uniconazole reduce gibberellin synthesis in lily plant and induce growth retarding.

Use of container gardens on the roadsides in Kwangju·Chonnam area was surveyed for a dta needed to make cities clean and livable. 30 different flowers were seen across area during the one-year observation. But 24 flowers except petunia, marigold, salvia, chrysanthemum(Pot Mum), flower cabbage were not so much popular. The top six popular flowers were all annuals or biennials which were easy to garden and longer duration of flower life. The 19 unpopular flowers, among which were there bulbs or tuber and woody plants, were used only in some distracts. The seven kinds of containers were noticed during the survey, and 95.8 percent containers were made of P.V.C and 64㎝×23㎝×17㎝ size. Seventy percents of the containers were located in the main streets and crossroads. Large and beautiful containers made of Mica or F.R.P. were located around public offices and bus terminals and more used yearly than made of other materials.

The effluent from conventional nightsoil treatment plants contains nutrients, color and chlorides, in addition to residual organics and suspended solids, and hereby causes substantial pollution problems in receving water resources. In order to verify the usefulness of electrolysis in removing those residual pollutants from such conventional nightsoil treatment plant effluent, a bench scale experiment was conducted using sufficiently diluted human nightsoil as experiment feeds. The result showed mean removals of 45% of total phosphorus and 85% of color, in addition to 87% of residual BOD, 47% of residual COD and 85% of residual SS. The uptimum electric current was found to be 15 ampere and the optimum hydraulic residence Time 21/2 hour.

To establish a basic data for developing materials of dry flowers, this writer had investigated on kinds and charaateristics of commersial dry flowers in the Korean domestic markets. Of a total of one hundred and twenty-nine dry flowers which are available in the Korean markets, sixty-one products are home-made, and the others foreign-imported goods. Herbal products are sixty-seven, and the rest sixty-two are woody plants. However, fourty(65.6%) kinds of home-made products are made of herbal flowers while fourty-one(60.3%) foreign products are woody plants. With the origins of the home products, Asia is 62.3 percent, whereas 29.4 percent of the imports are of Oceanian origin, and 27.9 percent of African origin. All in all of home and foreign products, 47 kinds are of Asian origin, 23 of Oceainan origin, 22 kinds of African origin, 14 kinds of European origin, and the rest 21 kinds of other origins. Many different parts of woody plants or herbs are used for the dry flowers; the 47 priducts are made of folwers, 41 products are of fruits and/or pods, 16 products are of ears, 13 products are of leaves, and 12 products are of stems, barnches or vines According to the purposes and usages, 32 products have more than two functions, 30 products are mass flowers, 29 products are form flowers, 26 products are line flowers, and 12 products are filler flowers. As to the methods of processing and treatment, 72 kinds are only dried up in the sun, 30 kinds are treated with both bleaching and coloring, 6 kinds are treated with bleaching or coloring, 5 kinds are treated with glycerine, 3 kinds are skinned, and 7 products are treated otherwise.
