This study was carried out to determine the optimum nodes of pinching and fruit setting in muskmelon cultured by deep flow technique. A fruit was set either at 7~8th, 11~12th, or 15~16th nodes, and main shoot was pinched either at 22nd or 27th node. Distance between rows was set the same at 100cm, while the distance between plant in the row was set at 25, 35, 45, or 55cm. In treatments with the same node of fruit setting, fruit quality was enhanced and mean fruit weight increased on 22nd node compared to 27th node. terms of fruit quality as affected by node of fruit setting, larger fruits with lower soluble solid concentrations were produced as fruits were set at higher nodes. In terms of planting density, larger fruits with higher concentrations of soluble solid were produced in the 100cm$\times$45cm and 100cm$\times$55cm treatments compared to 100cm$\times$25cm or 100cm$\times$35cm treatment. Total fruit yields decreased as the planting density decreased. However, percent marketable fruits produced was the greatest in the 100cm$\times$45cm treatment, followed in descending order 100cm$\times$25cm, 100cm$\times$35cm, and 100cm$\times$55cm treatments.

Sedum takesimenses among the Korean Native Genus Sedum was selected as evergreen ground covers during winter in the central districts of Korea. In order to obtain basic information for production as a pot flower with good quality, the effects of pinching frequencies on growth and flowering of S. takesimense were investigated. S. takesimense plant height became much shorter and numbers of lateral shoots were increased with increased pinching. Shoots of S. takesimense treated with 30% pinching during 2004 and 2005 showed greater length and less number of lateral shoots than those with 60% pinching. Leaves of S. takesimense treated with 70% shading showed a dark green color and had a longer shoot length and a lower number of shoots than cultivation under full sunlight. Therefore, Korean native S. takesimense will be utilized as ground cover treated with 70% shading or under a tree. Therefore, S. takesimense will be promising as ground cover materials in the central districts of Korea.

This research was conducted to investigate the effect of foliar application of 6-benzylaminopurine (BA), sprayed weeks after pinching (SWP), on ornamental usage of Veronica longifolia L, which is native to Korea. Foliar application of 0, 500, 1,000, and 2,000 mg/L BA on 10 cm long V. longifolia L. plant was evaluated at 0, 7, and 14 days after pinching for growth and flowering. The maximum result of multiple shooting was seen in the 2,000 mg/L BA at 1 week after pinching, and almost all the treatments showed dwarf growth in V. longifolia L. The number of days to flowering was delayed by BA treatments. Moreover, the length and the number of flowers decreased with high concentrations of BA. Thus, foliar application of BA via pinching technique can improve the ornamental usage of V. longifolia L. by controlling the plant type.

This experiment was carried out to determine the effects of topping time and fertilizer split application on the growth and root yield of Scutellaria baicalensis G. In case of stem cutting at 25cm above the soil surface early in July and middle in August, plant height was reduced by 37cm compared with nontreatment, but stem diameter, the number of branch per plant and the growth of root increased. Topping treatment twice produced the highest dry root yield (182kg/10a) of all, 15% higher than nontreatment. When nitrogen and potassium were applied by the basal dressing with 60% and by the top dressing early in July and middle in August with 20% in each time, the growth of plant (both top and root) increased. The dry root yield per 10a in top dressing twice was 12% higher than once.

In this experiment, the effects on the growth and the quality of cut flowers of chrysanthemum 'Jinba' were mainly concerned depending on cultural methods between the pinching and the non-pinching. According to the results, the sufficient period of the vegetative growth was necessary to enter the flower bud differentiation in case of the non-pinching cultivation whereas it was not the case on the pinching. As compared with the pinching, the non-pinching showed 10% higher in the flowering ratio after flower bud differentiation. The flowering ratio of the non-pinching exceeded more than 95% but the pinching showed below 95% of the flowering ratio after flower bud differentiation. Comparing the number of cutting flowers between pinching and non-pinching, it was the non-pinching that showed the production of the first grade cutting flowers about 5 weeks faster than that of the pinching. It seem to be possible that harvesting time and growing period could be shortened. In the non-pinching growing region, above third-grading marketable cut flowers was 100% regardless of planting time. On the contrary, the pinching method showed 84.7% of marketable cutting flowers at first week from the planting, followed by 64.3% at second week, 18.8% at third week, and 2.6% at fourth week. Marketability of cutting flowers indicates that were planted by the pinching is very poor. When draw a comparison between the fourth-week planting of the non-pinching with the first-week planting of the pinching, the non-pinching could cut the growing period 38 days shorter than the pinching and the marketability was better. These results indicate that the non-pinching method can shorten the growing period and harvesting time compared to the pinching and it also resulted in reduction of cost and rapid production of the cutting flowers.

This study is on the types and characteristics of foundation and basestone which can be seen in remains of Baekje and Silla in beginning study of them in ancient Korean architecture. This is a close investigation that division of the shape of the basestone and the type of Jeoksim(積心, the supporting part under the basestone) and foundation under the ground. Also it can be seen that the difference of construction technique and the relation with each part. The research objects are the remains of temples which had been excavated or are been excavating now in Baekje area and in Silla from 6th to 8th century. Results of research published in north Korea are quoted for the remains in Goguryeo being unable to be seen as they are in north Korea. If it had been possible to visit the sites, the materials would have been collected from the direct investigation. Otherwise they are collected from the excavaion results published. After that the basestone and the foundation could be divided according to several types. Also each types can be compared and studied according to times and building use. The results are follows. There are some different characteristics between Baekje and Silla in the technique of foundation, jeoksim, and basestone. Through them it is possible that the arhitectural technique of Baekje had been introduced to not only wooden pagoda in the erection of hwangryongsa temple. These results are considered limited in a few remains grasped the characteristics so it should be complemented continuously as the outcome of excavation of architectural remains will be accumulated to.
