These studies were carried out to know the measure of damage having an effect on the ornamental trees owing to sulfurous acid gas($So_2$) which injures much forest trees among air pollutions in south area of Korean and to know the difference of smoke resistance on the five representative species among them and therefore to establish the preventive measure of air pollutions in industrial complex of south area of Korea by the ornamental trees. The reaction formula utilized was $Na_2So_2+H_2So_4$ $Na_2So_4+H_O+So_4$. The results obtained were as follows. 1) The ornamental trees surveyed in the industrial complexes of Ul-San, Chang-Won and Po-hang belonged to 51 species, 161,699 trees in all. The most five species among 51 sorts of woody plants were Populus tomentiglandulosa, Buxus microphylla, Forsythia korenan, Juniperus chinensis and Pinus densiflora. 2) The relation between the concentration of sulfurous acid gas($So_2$) and the damage rate upon investigation in each species: In case of low concentration the destructive quantities of cells of woody plants, and the more increased the concentrations, the more increased the amount of damage. 3) The difference of smoke resistance among five species showed to be the strongest in Buxus micorphylla, the second rand Pupulus tomentiglandulosa, the third rand Forsythia koreana, the fourth rank Juniperus chinensis and the weakest in Pinus densiflora. 4) The ornamental trees of industrial complex expecially in south area of Korea in future should be planted gradually broad-leaved trees which have strong sprout, smoke resistance and thick leaved rather than comifers. 5) I think that the area of city forest in industrial complex requires about $50m^2$ per head of population and about 100m width of green belt between industrial area and residential district.

It is the purpose of this study to arrange in ornamental trees and shrubs the planting that leads to an appropriate type of templescape. The study was designed primarily as an examples for each Buddhist temple which desires further decoration with several ornamental plants, doubles the effectiveness of the Sen-Buddhist meditation, and boosts tourists' attraction. To investigate the planting status and type of trees and shrubs in the precincts of Buddhism temples, We close three temples : They are Nagsansa, Boolgoogsa and Booseugsa, which are intermonatane area temples all together. The results investigated were summarized as follows :1. Planting status and pattern in temples Open spaces of the Daewoogjeon in all temples, a main Sanctuaries in temple buildings, where Buddha is enshrined in, we could not find any kind of trees of shrubs to be planted.Muryangsujeon, a symbol of "Future", which can be also found at Boosugsa temple, is living in Western Elysium world and takes mercy on mankind of this life. Taxus cuspidata was planted at this Muryangsujeon, known as an immeasurable bliss building, where an Amitabha is enshrined in.Total 25 species of trees and shrubs were planted around Birozani building of Buddhist temples, Birozani is enshrined at the Birojion of Boollgoogsa temple.The buddhist Goddess of Mercy which is a buddhist saint for pursuit of fortune and blessing to relieve the mankind is enshrined at Wonchonjeon, Daebijeon and Kwaneumjeon which are able to observe at both Boolgoogsa and Nagsnsa temples, where Euonymus japonicus trees including other 26 species could be found in common at both temples.2. Correlation between trees/shrubs and temple buildingsTrees and flowers symbolizing Buddha are often planted as material sources of gardening to decorate : They are Logerstroemia indica as Buddha's flower, Viburmum opulus var. calvescens resembling Buddha's head, Tilia mandshurica producing the beads of rosary, Gardenia jaminoides Ellis with white flower blade and flower of bliss, not flower to this day and Lotus flowering clearly in the pond filling with dirty water which is able to clarifies the world full of crime, infidelity and injustification. Among these Buddhist' plants, however, Logerstroemia indica could be found in all three temples, and Viburmum opulus var. calvescens at both Nagsansa and Boosugsa. Also, Lager stroemia indica was planted at all three temples and Viburmum opulus var. calvescens at both temples of Nagsansa and Boosugsa. Tilia mandshurica and Gardenia jasminoides Ellis were not found in any temples which might become the subject of investigation.In relation of the buildings of each temples as a sanctified space, the planting of trees and shrubs was not considered for the arrangement, templescape architecture or species. And, also, we could not find in the study any special relationship of trees/ shrubs with the characteristics of temples.With the results obtained through precise studies we presented here in this paper newly designed model of templescape in intermane buddhist temple which can be applied for planting and arrangement of trees or/and shrubs. Basic principles of model in mind are:To consider the correlation of the dominant between plants and temple buildings.To plant trees/shrubs for special functions as well as conditions of temple location.To make tree arrangement correlating to Buddhism spirit.To induce environment friendly plants to be planted, suitable to regional conditions.This redecorated model of templescape might be used as a canon of the tree planting and arrangement in the precincts of Buddhism temples.

This study was to investigate the planting arrangement of ornamental trees and shrubs that leads to an appropriate, type of templescape. Temples sampled for this study were Woljonsa, Sineunsa, Sinreugsa and Mitasa which fall all under the category of the level land. The results obtained were as follows : Open space of Daewoongjeon in all temples, a main Sanctuary among temple buildings, where Buddha is enshrined in, we could not find any kinds of trees/shrubs to be planted. But tere were Acer mono, Acer planmatum, Crataegus pinnatifidam Raododendron poukhanense, Texus cuspidata and Buxus mincrophylla to be planted, before Jeokkwangjeon, in which Buddha is exceptionally enshrined. In Geugragjeon of both temples of Sinheunsa and Sinreugsa, and Elysium building and Muryangsujeon of Woljeongsa temple, an immeasurable bliss building, in which an Amitabha is enshrined. was Taxus cuspidata planted numerously found. Particularly, Josadang, Muryangsujeon and Samsungkag of Woljeongsa temple commonly had Sciadopiys verticillata, which is known as one of Japanese-favorite trees. Syinga oblata Lindaley was also observed at Jeokkwangjeon of Woljeongsa temple and Keungnakjon of Sinheungsa temple, and Vidurnun opulus var. calvesvens, a symbolic flower tree imaging Buddha's head, was planted in Myungboojeon of Sinheungsa temple and Keugnakjeon of Sinreugsa temple. Juniperus chinensis which could be observed in both temples Sinheunsa and Sinreugsa was well arranged enough to be easily captured by human's eyes. In terms of templescape that might be considered in templescape, the correlation between trees/shrubs and temple buildings was thoroughly discussed. And, with the results obtained through precise studies, we presented here in this paper newly designed model of templescape in level land buddhist temples which is possibly applied for planting and arrangement of trees or/and shrubs.

This study was carried out to develop new cultivars of Z. serrata showing red fall leaf as street trees. Z. serrata which had red fall leaves were selected and then examined for contents of leaf anthocyanin and chlorophyll. In addition, for the progeny test, selected trees were grafted. Of 21 trees having red autumn leaves, three individuals, 'S-6', 'S-20', and 'I-24' were finally selected. They contained higher level of anthocyanin in the leaves. Once developed, the red color remained till late autumn. Grafted plants of the selected strains showed high grafting efficiency and red foliage color in autumn. The soil pH of the survey sites ranged from 5.9 to 7.24. However, other soil characteristics did not show much difference among the sites with regard to inorganic nutrients including N(%), $P_2O_5$, CEC(mg/meq), $K^+$, $Ca^{3+}$, and $Mg^{2+}$, 'S-6', 'S-20', and 'I-24', clonal lines with red fall leaf were selected as new cultivars and propagates by grafting.

Campsis grandiflora (Thunb.) K. Schum is an ornamental species with various useful biological effects. The chloroplast genome of C. grandiflora isolated in Korea is 154,293 bp long (GC ratio: 38.1%) and has four subregions: 84,121 bp of large single-copy (36.2%) and 18,521 bp of small single-copy (30.0%) regions are separated by 24,332 bp of inverted repeat (42.9%) regions including 132 genes (87 protein-coding genes, eight rRNAs, and 37 tRNAs). One single-nucleotide polymorphism and five insertion and deletion (INDEL) regions (40-bp in total) were identified, indicating a low level of intraspecific variation in the chloroplast genome. All five INDEL regions were linked to the repetitive sequences. Seventy-two normal simple sequence repeats (SSRs) and 47 extended SSRs were identified to develop molecular markers. The phylogenetic trees of 29 representative Bignoniaceae chloroplast genomes indicate that the tribe-level phylogenic relationship is congruent with the findings of previous studies.

This paper outlines the system and operation of plant variety protection right and plant patent of ornamental crops in USA to guide for application of new varieties developed in Korea and to use for national examination of applied variety from USA. The Plant Variety Protection Act(PVPA) in USA is given as PVPR to the developers of new variety for the seed propagating crops and tubers and provides as plant patent for asexually reproducing crops. A certificate of PVPR and plant patent is awarded to an owner of a variety has shown that it is new, distinct from other varieties, genetically uniform and stable through successive generations by official evaluation without the growing trial. The term of protection for plant patent and PVPR for most crops is 20 years but 25 years for trees, shrubs, and vines. The application of ornamental variety in USA is mostly for plant patent. The application of ornamental crops accounted for 87% of total applications for plant patent. The ratio of new variety applications for plant patent from national and foreign countries is not significant differences.
