The purpose of this study is, focusing on the ancient paintings and literatures, by examining Flowering Plants and drawing their cultivating methods, to provide a ground of utilizing them on the modern landscaping. In the scope and method of this study, 766 pieces of ancient paintings(6 garden paintings and 760 folk paintings) which were available and had value as literatures, and 8 of ancient literatures were intensively examined. Main results extracted from them are as follows. First, the most frequently used Flowering Plants in Joseon Dynasty were Prunus mume, pbyllostachys, Nelumbo nucifera, Chrysanthemum morifolium, Musa basjoo, Rosa spp., Rhododendron mucronulatum, Paeonia lactiflora, which appeared 11 times to 16 times in total. Next frequently(4 times to 8 times) used Flowering Plants were Gardenia jasminoides, Punica granatum(8 times), Dianthus chinensis, Vitis vinifera(7 times), Orchidaceae, Syringa velutina, Impatiens balsamina, Hemerocallis fulva, Celosia cristata, Hibiscus Syriacus, Rhododendron indicum(6 times), Rhododendron, Rhododendron obutusum, Acorus calamus, Althaea rosea, Kerria japonica, Citrus junos(5 times), Hibiscus mutabilis, Lychnis cognata, Calendula officnalis, Begonia rex., Helianthus annuus, Papaver spp., Narcissus tazetta, Daphne odora, Hosta plantaginea(4 times). Second, usage of the Flowering Plants in Joseon Dynasty can be divided into character building and horticulture for pleasure through positive, scientific approach attempt. It suggests that there might have been classes in the use of them and we can estimate which plants were particularly preferred. Third, in the symbolicity of the usage of Flowering Plants, it can be divided into three parts: The case of representing integrity, gentleman, honesty and nobility and the thought of loyalty and filial piety under the influence of Confucianism. The case of representing Taoism's thought of hermit and perennial youth and long life. The case of representing wish on wealth and prosperity. So if we make a good use of it, we may draw a meaning of cultivation of Flowering Plants from it. This is your target audience or the good luck to all he plants is aimed at, you can see the occurred. Fourth, the Joseon Dynasty was the use of flowering plants are the line of rain wanted to be more consistent with the spirit world. This is shown as a symbol of their ancestors. Joseon Dynasty was used, resulting in a kind of flowering plant and is not a subjective judgement criteria A psychological approach to the side when interpreting the Joseon Dynasty flowering plants to take advantage of the landscape of the area will widen in scope.

We investigated the host preference of Ricania app. at different developmental stages to select the effective control methods. Ricania spp. at different developmental stages preferred different host plants. During the nymphal period, individuals moved to the bottom due to environmental factors such as wind and rain, rather than inhabiting trees, and fed on various plants ranging from 1 year-old herbaceous plants to shrubs. Especially, at Palbong Mt. in Gonju, Ricania spp. nymphs preferred Symplocos chinensis f. pilosa, Celastrus orbiculatus, Euonymus alatus, Kalopanax septemlobus, Aralia elata, Styrax japonicas, Rubus parvifolius, Ru. coreanus, Ru. crataegifolius, Quercus acutissima, Cornus officinalis, Lespedeza bicolor, Albizia julibrissin, L. maximowiczii, Rhododendron schlippenbachii and Rh. indicum. At Yongbong Mt. in Hongseong, Ricania spp. adults preferred herbaceous plants, such as Helianthus annuus, Solanum nigrum, and Oenothera biennis rather than trees during the pre-oviposition stage. Subsequently, as the oviposition season began, Ricania spp. adults were rarely found in H. annuus, S. nigrum, or O. biennis and appeared to migrate to the perennial trees and shrubs hosts to lay eggs. At Palbong Mt., the main laying hosts of Ricania spp. adults were Weigela subsessilis, Ailanthus altissima, Q. aliena, Boehmeria platanifolia, Diospyros lotus, Ziziphus jujubae var. inermis, St. japonicus, Prunus mume, P. serrulata var. spontanea, Spiraea prunifolia f. simpliciflora, Ru. crataegifolius, Salix koreensis, Ru. yedoense f. poukhanense, and Co. controversa. The degree of egg laying, number of egg masses and adult Ricania spp. were significantly higher in sunlit areas than in shaded areas, in addition, the lower the altitude, the more adults were present. This study contributes toward the development of traps that can attract and control Ricania spp. and reduce the density of Ricania spp. that disturb the ecosystem.

This study was conducted to obtain basic informations for breeding and improving cultural practices of sesame (Sesamum indicum L.) through investigation of several agronomic characters of 82 major varieties plants in April 20, May 15 and June 20. Stem diameter and plant height were largest in early planting(April 20). On the contrary, they were smallest in late planting(June 15). Therefore, the later planting, the poorer the vegetative growth on the basis of stem diameter and plant height. Number of capsules per plant and number of grains per capsule were 88 and 54, respectively, in the early planting, while they were decreased to 25 capsules and 40 grains in late planting. The percentage of ripeness and 1000 grain weight 78 and 2.3g in the April 20planting while they were 58% and 2.1g in June 20 planting indicating the later planting, the lower the ripeness. Grain yield per m1 in April 20 and June 20 planting was 112 and 18g respectively. Consequently, grain yield significantly decreased as planting delayed. On the basis of the vegetative and reproductive growth, varieties could be classified into early, conventional, late and indetermediate planting adapted groups. The major yield components were highly and postively correlated with accmulated sunshine hours and temperatures confirming that grain yield was closely related with sunshine and temperature. Among the varieties tested, Gurye and Local 135 had more than 150 capsules. Haenam and Woogang had more than 75 grains per capsule. Since grain yield oflate planted sesame were significantly different among the varieties, breeding of sesame for after barly cropping would be more effective under late cultural condition of after barly.

This experiment was performed to investigate the flowering habit of sesame (Sesamum indicum L.). Sesame varieties tested could be classified into 8 different plant types by their morphological traits such as capsule shape, capsule setting habit and branching types among sesame gene pool of Crop Experiment Station, ORD. The first flower was appeared at the lowest node on main stem. Flowers were appeared progressively toward the tip of the main stem and also toward the tips of branches. The interval of flowering for a node was about one day, but 3 to 8 days for the flowers on the tips. Side flowers started at 4 to 5 nodes lower than those of center flower at the same day. Flowers were beared 2 by 1 node on the middle part of flower setting node (7-9) in mono capsule setting habit in spite of its normal is 1 by 1 node on the other nodes. Flowers were beared opposite direction on each node of stem and flowering toward the tip of main stem composed of cross shape between nodes and spiral, reverse of clockwise direction. We called this habit as cross spiral flowering order and cross spiral phyllotaxis. The first flower on branches was appeared when center flower on the 5th node of main stem began to flower. The branches produced at higher nodes on main stem showed larger flowering periods and more number of flowers than that at lower parts. BTB (Branch, Tricapsule, Bicarpels, 4 Loculi) type showed three capsule setting habits and same flowering period both on main stem and branches while BTQ (Branch, Tricapsule, Quadricarpels, 8 Loculi) type showed three capsule setting habit on main stem and mono-capsule setting habit on branches. In BTQ type, the period of flowering was much shorter on branches than on main stem. Branching type was considered more promising than non branching type for the breeding of early maturing high yielding variety because branching type has the advantage of bearing a lot of flowers in comparatively short flowering period.
