This study was carried out to analyze physico-chemical properties of soils at the ground of landscape planting in reclaimed land from the sea on Kwangyang Bay, South Korea. Physico-chemical properties of soils at each planting grounds were tested by ANOVA and were significantly(P<0.01) different. The difference came from the soil properties of the covered soil, the disturbance applied to the soil with land use and the accumulation of organic matter after landscape planting. Soil hardness, pH, ECe, Na and K level were in a stable condition at high then low of ground height for landscape planting. Organic matter accumulation was greater at lower planting grounds then top and slope ground of big mounding. The planting grounds of favorable growth for landscape trees were determined as following order : the slope ground and the top ground of big mounding>the ground of medium mounding>the coved ground of improve soil>the lower ground of big mounding>the filled ground of improve soil.

Securing sufficient planting strip for street shrubs has a limitation. So many different shrubs which have been planted in the streets looks consider its visual aspect rather than growth characteristics. In this study, we compared with the growth condition of planted shrubs and construction condition of its planting strip. $Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$, $Nandina$ $domestica$, $Abelia$ $grandiflora$ were selected in the Busan City, Korea. The planting strips width were 0.5~0.9m which is not relatively different by each species. Species which have narrow growth character of root hair in the natural bed ($Nandina$ $domestica$, $Abelia$ $grandiflora$) have a good growth condition in the street planting strip, oppositely shrubs which have wide growth character of root hair ($Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$) have a relatively bad growth condition. Hereupon, there have a necessity which should be select the different shrub species for the planting strip of the street.

In order to determine the optimum planting density of Sickle Senna (Cassia tora L.), agronomic characters, yield components and grain yield were investigated under vinyl mulching and non -mulching condition. The characters, stem length, stem diameter, number of branches, number of pods per plant, number of pods per m$^2$, and number of grains per pod, etc., were excellent under the vinyl mulching condition, and number of pods per m$^2$ was the highest in 60$\times$15cm planting space under vinyl mulching or non-mulching. Both of the weight of 100 grains and grain yield were also higher under the vinylmulching condition, and grain yield was the most excellent in 60$\times$15cm planting space under the vinlymulching, or non-mulching. Under the vinyl mulching and non-mulching, the analysis of variance for agronomic characters following the difference of planting density, were acknowledged to be worth of attention.

This study was conducted to grasp the present condition of the name and the related text of the domestic laws (97 statutes, 1 examination, 1 guide, 3 ordinances, 1 leading case) in force which were connected with landscape plant and planting. Examining the general tree-planting system of America, the related foreign laws(1 constitution, 44 statutes, 31 ordinances, 6 leading cases) were arranged in the name and the text and classified by nations of regional groups and it was considered to the mutual relation with lots of laws which are scattered with the various laws. To examine the points at issue of the related domestic laws and to study the related foreign laws, the remedies for the domestic laws being at issue were proposed. That is : A change of the landscape planting concept, the introduction of the landscape planting cost compared with the total construction cost, the unification of the landscape planting ordinances as the unit of city, the clarification of the completion period for the depect of the replaced trees. putting the conservation and production of the top soil under an obligation the adoption of a licence system for the tree planting within the river area, the introduction of the allotment system for landscape architectural expenses, the encouragement of making a hedge, the settlement for the problems of the trees loss compensation, the necessity for the quality test to the landscape planting works, the intensification of the punitive rules to the illegal felling and planting of the trees in the greenzone area, the application of the Labor Standard Act to the landscape planting laborers. The laws relating to landscape plant and planting are prescribed dispersedly in the many other related laws and it is concluded to be impossible for the legislation of the singular law which is applied uniformly to the department of the tree-planting. Hereafter it should be required to analyze concretely in detail the each text of the related laws by means of the joint studies between the professional landscape architects and the lawyers.

This study was conducted to determine the optimum planting distance under rain-shielding condition for improving quality and productivity of squash by staking cultivation. The squashes were grown by 3 planting distances, such as 120${\times}$30, 120${\times}$40 and 120${\times}$50 cm during 3 months under non heat condition. The vine length, fresh weight and leaf area were reduced as planting distance was decreased until main branch was pinching. The first female flowering day and first fruit setting nodes were not different among treatments. The first fruit length and second fruit weight were increased in 120${\times}$50 cm planting distance, but the soluble solid contents were not different among treatments. In 120${\times}$30 cm plant distance, total yield was highest (6,510 kg/10a), but marketable yie이 was lowest. When the planting distance was between 120${\times}$40 cm and 120${\times}$50 cm, the marketable rate was similar (over 98%), but marketable yield was highest in 120${\times}$40 cm planting distance (5,012 kg/10a). The results of this study indicated that the optimum planting distance of staking cultivation in squash seemed to be 120${\times}$40cm.

The purpose of this study is to propose an evaluation method to assess green environments of streetscapes to improve urban street green spaces in Jeonju City. Through a rapid assessment of urban street green spaces, we suggest an objective basis for expanding street green space as well as for adopting sustainable maintenance and improvement measures. We choose 12 sections of streetscapes (roads and sidewalks) to investigate existing street conditions which have more than four lanes and function as major road axes. Six large roads and six medium roads of Jeonju City center area are investigated as pilot assessment study sites. Site inventory checklists consist of environmental characteristics of streetscape, street tree status, and planting condition evaluation. Environmental characteristics of streetscapes are composed of physical and neighborhood factors. For instance, items for physical factors are types and width of road/sidewalks, paving materials, tree protection materials, and green strip. And surrounding landuse is a neighborhood factor. Assessment items for street tree status are street plant names (tree/shrubs/ground cover), size, and planting intervals. Planting condition evaluation items are tree shape, damage, canopy density, and planting types with existence of adjacent green space. Evaluation results are classified into three levels such as A(maintain or repair), B(greening enhancement), and C(structural improvement). In case of grade A, streetscapes have enough sidewalk width for maintaining green strip and a multi-layered planting(in large road only) with fairly good growing conditions of street trees. For grade B and C, streetscapes have a moderate level of sidewalk width with a single street tree planting. In addition, street tree growing conditions are appeared poor so that green enhancement or maintenance measures are needed. For median, only grade B and C are found as its planting growing foundations are very limited in space. As a result, acquiring enough sidewalk space is essential to enhance ecological quality of urban street green. Especially, it is necessary to have green strip with reasonable widths for plant growing conditions in sidewalks. In addition, we need to consider native species with multi-layer plant compositions while designing street green.

This study was executed to investigate matters connected with planting of Gapho Citizen's Woods(Park), and to offer the data about countermeasure. The study was executed in 1988 and 1989. The contents of the study were the condition of plants, the environmental factors, the states of tree planting and the user's behavior. The result of this study can be summarized as follows. 1. Because of incongruity of soil and regardless of physiological properties of trees, the plants were damaged by their environment. In particular, the stress of soil moisture was serious. 2. The unsuitable planting forms for the park were found out through the park, which was the result of imprudent, additional planting. And so in planting trees additionally, the participation of landscape architect is needed. 3. There is a serious noisy problem from express way. Because when they planted trees, they did not consider about noise. It affected the quality and utilization of the park.

One of the most important cultural techniques of pearl millet (Pennisetum americanum (L.) Leeke) is to encourage rapid and uniform emergence of seedlings to establish good stand and to let them grow well. Thus the objectives of the study were to investigate the effects of pre-sowing seed soaking and planting depth on dormancy breaking, germination and emergence of the seedlings, and to estimate the optimum planting season of pearl millet in Suwon, Korea. The seeds with dormancy germinated 99 to 100 percent when soaked in the H$_2$O$_2$ 1％ solution for 24 hours and rinsed with pure water, but germinated only 38％ and 83％ when soaked in pure water for 24 hours just after harvest and drying, and one month later from the harvest time, respectively. The seeds of Australia inbred line did not germinate at the constant 10$^{\circ}C$, but germinated at the constant 11$^{\circ}C$. It also was possible to estimate the optimum planting season by applying minimum temperature 11$^{\circ}C$ for germination. The minimum air temperature reached from late April in Suwon, Korea in regular years but fluctuated from late April to early May in 1986 and 1987. Thus, the safe planting season was mid-May for rapid and uniform germination of pearl millet seed. The optimum depth of planting was 2∼4cm under the optimum soil moisture condition, and 4 to 6 cm under the drier soil moisture condition. Subcoleoptile internode(mesocotyle) length increased according to increased depth of planting. Seedling crown placement also became deeper due to deeper planting of the seeds. The subcoleoptile internode length and seedling crown depth were positively correlated with actual planting depth, indicating that deeper planting would be not good for appropriate adventitious root and tiller development.

Large trees in the apartment complex are playing an important role to decide the quality of external environment. They are planted with the object of utilizing themselves as a landmark of the complex and enhancing space symbolism. Since planting large trees would require high maintenance costs and generate defect, it would cause decline in quality of external environment. This study researches on large trees in artificial ground of the apartment complex. This study analyzes actual condition of planting and tries to provide improvement direction of planting. In order to conduct this research, three target areas (over R30) and 265 trees are selected. Based on the drawings and specifications this study researches on the plan of landscape design, changes of field design, actual condition of completion, present condition of planting, minimum soil depth of growth and development and types of extra action for soil depth. The result shows that 85% of drawings and specifications for large trees in the apartment complex are deep-rooted tree species. On average large trees with R 35 are planted in artificial ground and there is lack of on average 65cm minimum soil depth of growth and development. Reviewing changes of field design is conducted in such limited size as mainly R30 and R40 and there is no extra plan for lack of soil depth. The plan for securing additional soil depth is done by 85% of mounding. However, since there is only 10% of satisfaction, the inappropriateness in securing additional soil is pointed out. This research also points out that the size of large trees, root characteristics and location-allocation for planting are pivotal factors for securing minimum soil depth of growth and development. This research also provides improvement direction in case of planning planting.
