  • Floret flowering of a monocarpic plant Orostachys japonicus should be controlled to change its harvest time. The study was done to clarify the effect of pinching time of inflorescence with many florets (Aug. 25, Sept. 8 and 22, Oct. 4) on its growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done since Aug. 25 when afterward samples were taken every 2 weeks to Nov. 4. Growth, morphological and flowering related characters were measured from each sample. Plant height, inflorescence length and number of leaves including bracts showed significant difference between the treatments because they were sharply increased until each pinching time. Stem diameter did nearly same. Leaf and bract, floret, shoot and total dry weights had similar response to the plant height, but stem and root dry ones did similar response to the stem diameter. Most florets were removed by the pinching treatments after formed ones were increased until each pinching time. Few florets were left after the treatment, meaning that night-break treatment after that could be skipped.

  • ${\ll}$Hua shu${\gg}$ is one of the Taoist scriptures written by Tan qiao, a taoist in the late Tang dynasty. The logical structure of his scriptures is very complicated, and its content is profound though it has few pages. To understand ${\ll}$Hua shu${\gg}$ precisely the key words which appear in the Taoism scriptures have been examined. The most important words are: 'Tao', 'Emptiness', 'Shape', and 'Variation'. Tan qiao tried to explain nature, human, and society changes by using these key words, and also asserted that humans can affect their change; we slow our aging, more or less; we prevent our society from its decay and make it stable, more or less. Tan qiao asserted the autonomous feature of humans in ${\ll}$Hua shu${\gg}$ which shows how man manages his own life rather than being stuck in his destiny. This goes the same for society. "One's destiny is not fixed but changeable through his efforts". In Taoism, humans are not beings who have no chance to make change other than living their given destinies but are autonomous. This is again what the Taoist Tan qiao wanted to make clear.

  • This thesis examines the reality of Hwaseo's view of scholarship established through the various academic roots, and explains the writing techniques in his poetic world. The results are as follows; With the roots including the Five Books of Confucianism, Five Classics, the books of Zhuxi and Songjadaejeon, Hwaseo established his own scholarship based on the principle of 'keeping of piety and acting with prudence(持敬致愼)'. And he pursued a practical discipline in parallel with 'understanding the utmost principle and extension of knowledge(致知)' and 'diligent self-cultivation(力行)'. The characteristics of his poetic techniques are the use of quotation and interweaving narrative with discussion. He did not stay in just borrowing or variations on the quotation, but gave new meanings beyond the acceptation, and even reached the point of creating newly coined words. He made pithy narratives according to historical events and character's activities, put forward some discussions, and then expressed his emotion. In particular, there were the poems described by interweaving narrative with discussion based on Mencius's historical viewpoint of 'repetition of peaceful times and troublous times one by one(一治一亂)', which could be regarded as the most representative works of his literary value as well as the essence of his scholarship and ideas.

  • This experiment was conducted to investigate the effects of growth retardant uniconazole on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One'. Reduction in leaf length of both cultivars was proportional to the amount (0-5g) of uniconazole and growth reduction of 'A One' was more remarkable than 'Moon Venus'. The inflorescence length was reduced 18.4% in 'Moon Venus' and 15.3% in 'A One' by 5g treatment of uniconazole. There was no significant difference in flowering time, number of inflorescences and florets and size of lower sepal regardless of uniconazole treatment. It was concluded that uniconazole treatment is effective in reducing the leaf growth of Cymbidium. However, as high concentration (5g) of uniconazole reduced the growth of inflorescence causing low quality, 1g was recommended as useful concentration.

  • This experiment was conducted to investigate the effects of a growth retardant uniconazole treatment time on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One' in order to develop a substitutional technique on the highland cultivation. Leaf growth of both cultivars was more remarkably reduced by earlier uniconazole treatment time and growth reduction of 'A One' was more remarkable than 'Moon Venus'. Flowering time of 'Moon Venus' treated with uniconazole at May 7 and 27 was accelerated by 5 and 6 days respectively. Moreover, the number of inflorescences and florets showed a tendency to increase. However there was no difference in flowering time of 'A One' among treatments but there was a tendency to decrease in the number of inflorescences and florets by uniconazole treatment. In both cultivars, there was no difference among treatments in the length and width of lower sepal which represent the floret size.

  • This experiment was conducted to investigate growth and flowering characteristics of Celosia argentea native to Korea treated by pinching and growth retardants, diniconazole, hexaconazole and daminozide. The more increased from one to three times of pinching, the more decreased in plant height and internode length but increased number of spadix and lateral branch. Spray application of diniconazole $50mg{\cdot}L^{-1}$ and daminozide $6,800mg{\cdot}L^{-1}$ decreased plant height, internode length and leaflength, but increased number of spadix, number of leaves and number of lateral branch.

  • The objectives of this study are to examine the context of the establishment of Suhoe Gugok, Byeokgye Gugok Vally, and Nosan Palkyung, which have been established in Seojong-myeon of Yangpyeong-gun, by literature review and site investigations, and to determine the sceneries of Byeokgye scenic site as enjoyed and managed during the period of Hwaseo Lee, Hang-ro(華西 李恒老). The results of the study are as follows. First, Byeokgye Gugok Vally(黃蘗九曲) and Nosan Palkyung(蘆山八景), which have been established after the period of Hwaseo and theorized to have been established around key scenic areas associated with Hwaseo's activities, the analysis results showed that they were collecting sceneries of modern times. The extensive overlap between Byeokgye Gugok Vally and concentrated scenic elements of Suhoe Gugok(水回九曲), and the artificial configuration from the end point of Suhoe Gugok to the beginning point of Nosan Palkyung, reveal the pattern of space conflict and hegemony between Byeokgyes of Suip-ri and Nomun-ri. This is likely to be caused by the conflict between the historicity of the group that enjoyed Byeokgye prior to Hwaso's period and the strong territoriality of the space filled with the image of Hwaseo. Second, Byeokgye Gugok Vally was the secondary spatial system created by selecting the most scenic sites in Suip-ri while expanding the area of Nosan Palkyung. After establishment of Byeokgye Gugok Vally, the spatial identity of the entire Byeokgyecheon area was effectively established. This was a "Hwaseo-oriented" move, including the complete exclusion of the scenic sites from the pre-Hwaseo period such as Cheongseo Gujang and Suhoe Gugok's Letters Carved on the Rock. Consequently, the entire Byeokgyecheon area was reorganized into a cultural scenic site with Heoseo's influence. Third, Fifth, creations of Gugok(九曲) to determine the lineage of the Hwaseo School from Juja(朱子) to Yulgok(栗谷) to Uam(尤庵) to Hwaseo is likely to be an opportunity of birth and external motivation of the establishment of new Gugok Palkyung. In other words, Nosan Palkyung and Byeokgye Gugok Vally are likely to have been created as a reaction to the change of the center of the Hwaseo School to Okgyedong, and with strategic orientation based on the motivation and needs such as creation of the connecting space between Mui Gugok, Gosan Gugok, and Okgye Gugok, and the elevation of Hwaseo's status. Fourth, from the Hwaseo's Li-centric point of view, all revered sites in Beokwon(蘗園) that he managed existed as the spatial creative work to experience the existence of "li" through the objects in the landscape and the boundary of the spirit of emptiness of the aesthetic self. This clearly shows how Byeokgye Gugok Vally or Nosan Palkyung must be defined, and furthermore, appreciated and approached, prior to discussing it as the space associated with Hwaseo. Fifth, Nosan Palkyung was composed of cultural scenic landscapes of Gokjungkyung(曲中景) with eight scenic sites where Hwaseo gave his teachings and spend time around, in the Byeokgye of Nomun-ri area of Byeokgye Gugok Vally. The sceneries is, however, collected by depending on Hwaseo's Letters Carved on the Rock and poetry. Consequently, an inner exuberance of Nosan Palkyung is satisfied beside Byeokgye Gugok Vally, but its conceptual adequacy leaves room for questions.

  • To establish the proper size of seedling of A. gigas, different weight of seedlings were used for this study. Agronomic characters including plant height, number of leaf, leaf length, number of inflorescence, fresh weight and rate of bolting of the aerial parts, root length, root diameter, number of lateral root and root weight of the underground parts were determined and correlation coefficients among them were estimated. Growth of A. gigas showed the significant vigor for all the characters of the aerial parts along with increasing of seedling weight, but root weight in yield decreased in proportion to increasing of seedling weight due to lignification of the root tissue. When the smaller seedlings were transplanted, bolting rates decreased to about 16% as compared with the traditional size of seedlings. Correlation coefficients between aerial and root characters in A. gigas were negative, and the characters such as plant height, number of leaf, number of inflorescence and fresh weight per plant showed highly significant correlation with the rate of bolting which is one of the characters having great influence on yield.

  • For nine taxa of the genus Carex which consist of C. arenicola, C. chordorhiza, C. curta, C. gibba, C. laevissima, C. leiorhyncha, C. neuromrpa, C. maakii and C. remouscula with mixed pistillate and staminate flowers, morphological characters such as inflorescense, spikelet, inflorescence bract, utricle, pistillate and staminate scales, achene, length between two spikelets were observed to find useful characters for their identification. Especially, the shape and the number of spikelet were very useful characters to divide the treated nine taxa into two groups, the their keys were prepared. The first group was comprised of five species of C. arenicola, C. chordorhiza, C. curta, C. gibba, and C. remouscula, which were characterized by broadly oboval or narrowly elliptical shape of spikelet, and 3-9 spikelets per infIorescence and gradual decrease in length between two spikelets. The second group was composed of four species of C. laevissima, C. leiorhyncha, C. neurocarpa, C. maakii, which were distinguished by oval shape of spikelet, and 17-20 spikelets per infIorescence and repetition of increase.

  • To determine the optimum N rate m Jeju island for utricle and root production of Achyranthes japonica Nakai, a medicinal plant, the plants were grown at two plant densities $(50\;and\;100\;hills/m^2$, two plants per hill; mall plots) at six N application rates (0, 6, 12, 18, 24, and 30 kg/10a; split plots) in 2001. There was no significant interaction between plant density and N application rate for all measured agronomic characters. Main root length and roots per hill were 5 and 52% greater, respectively, but N content of stover was lower under lower plant density compared to higher plant density. The other characters were not affected by plant density. N application rate did not significantly affect mall stem diameter, spikes per hill, spike length, utricles per spike, mall root length and diameter, and utricle N content. As N rate increased from 0 to 30 kg/10a, SPAD values and stover N content increased linearly from 35.0 to 40.5 and 1.09 to 1.38%, respectively, and plant height, branches per hill, stover, utricle and root dry matter yields, roots per hill, and top N yield increased quadratically. Spikes per hill were increased in a cubic manner with increased N application rates. N application rate for the maximum dry matter yield of utricle and root in A. japonica was estimated to be 21 kg N/10a.
