The purpose of this study is to analyze the profitability by selecting Pinus densiflora S. et Z. worthy of ornamental tree from among the cutting timber in the urban development project, and then presents the improvements. The study site is the whole area of Oedong-eup Gyeongju city Gyeongsangbuk-do and subject trees numbers are 2,180 trees. Analysis method is cost analysis because it is used generously pubic land development. In results, at first, in case of forest development currently cutting tree costs 7.3 million Won/ha. and no profit is occurred at all. Secondly, the forward direction order of tree treatments expenses are in sawdust production, selling lumber, selling ornamental tree, and selling ornamental tree, sawdust production, selling lumbered on the aspect of profits by the selling stumpage. Especially, selling trees as ornamental tree costs 127 million Won/ha. which shows the highest profits. Third, the management of ornamental tree pine tree after transplantation from development site costs 5 times less than purchasing the same quality trees. Hence, it is recommended to re-utilize the trees from the development sites to produce a high standard gardens and it also provides the basis for the low carbon green growth society.

The wild Pyrus plants belong to the deciduous woody plants in Rosaceae family. Most are cultivated for fruit productions, but some for ornamental plants. There are 5 Pyrus species including Pyrus ussuriensis and 8 varieties cultivated in Korea. In Korea, these plants are populated near villages or on the hills, and they are easily propagated since their fruit are very juicy and quite big in size. Plant breeding to get improved cultivars is not difficult because the Pyrus plants are easy to cross breeding among its genus. Because not only this reason but there have been shown lots of variation in wild groups, the Pyrus plants inhabited in Korea are excellent deciduous woody plants and favorable fruit trees to develop ornamental plants. It is necessary to develop many kinds of fruit trees and ornamental trees containing genetically different character, so that it will be satisfied for many different people's taste and demands. Collecting lots of wild plant resource with diverse genes is necessary for plant breeding.

The purpose of this study was to analyze the village groves in Pohang city by classifying them into 5 categories: sage plantation, shelter-belt plantation, shore plantation, ornamental plantation and bower plantation. The results of this study can be summarized as follows; The village groves in Pohang city consist of 16 sage plantations ($128,682m^2$), 14 shelter-belt plantations ($807,755 m^2$), 17 shore plantations ($447,616m^2$), 10 ornamental plantations ($141,276m^2$) and 6 bower plantations ($79,075 m^2$). Namely, the ratio of shore plantations is highest (n=17) in terms of number, while that of shelter-belt plantations is highest (50.3%) in terms of area. On the other hand, Pinus Thunbergii account for the absolute majority (n=55,239, 74.1 %) of the trees, followed by pine trees (n=18,017, 24.2%). Both species are combined to account for 98.3% of the entire trees, which means that the plantations are simple in terms of tree species When the village groves were compared in terms of functional age, sage plantations are oldest or aged 143 years, followed by bower plantations (aged 137), ornamental plantations (aged 118), shore plantations (aged 92) and shelter-belt plantations (aged 88).

매년 새로운 식물바이러스병이 보고되고 있지만, 이들 대부분의 바이러스들은 곡류, 채소류 및 화훼류와 같은 초본식물에서 발견된 것으로서, 상대적으로 목본식물의 바이러스는 잘 알려지지 않고 있는 실정이다. 한편, 현재까지 국내에서 보고된 목본식물의 바이러스는 17 종으로 11 종의 수종으로부터 분리되었다. 이와 같은 목본 식물의 바이러스병은 대부분 과수나 원예용 수목에서 발견되었는데, 그 이유 중의 하나는 임목보다 과수나 원예용 수목이 경제성이 높기 때문으로 추정된다. 다수의 식물바이러스가 초본 식물 뿐만 아니라 목본식물에도 피해를 준다는 사실을 생각해 볼 때, 보다 더 많은 연구가 수행된다면, 앞으로 많은 수의 목본식물 바이러스병이 밝혀질 것이다. 이 논문은 현재까지 국내에서 보고된 목본식물 바이러스병에 관한 총설이다.

경기도 의정부시에 위치하고 있는 도봉농장내에서 생육하고 있는 조경수목이 인근 공장의 연료연소시 발생되는 $SO_2$ gas에 의해 피해를 입어 고사된 것을 조사한 결과를 요약하면 다음과 같다. 1. 피해수종별 엽내유황함량을 분석한 결과 피해가 심할수록 전유황함량이 증가하는 각수종에서 나타났다. 농장서쪽 경계선에서 $70\~120m$ 거리가 피해가 가장 심하였고, 여기서 전유황함량이 가장 높았다. 또한 전유황함량의 최대치가 $0.5\~0.6\%$인데, 이러한 피해가 발생된 것은 급성적인 피해가 기온의 차이가 큰것에 기인된다. 2. 향나무에서 동일개체내의 건전부위와 피해부위의 전유황함량은 유의적인 차이를 보였다. 2. 엽조직의 해부학적 조사에서 피해엽은 공통적으로 갯솜조직과 표피세포의 원형질분리가 일어나 수축 파괴가 일어났고, 또한 세포간극과 기공주변이 넓어진다.

This study aimed to select evergreen broad-leaved trees (EBT) that can be produced and planted in Korea by analyzing the current use of the trees for landscaping in the Kyushu area of Japan, a warm temperate region. The results revealed the total production of EBT was higher than that of conifers and due to the suitable growth environment of the area and the subsequent high demand for them. The landscape tree production methods in Japan were divided into container nursery and outdoor nursery, and the uses and species of the trees varied depending on the method; a variety of native species were produced in container nursery rather than in outdoor nursery, whereas trees used as ornamental, gardening, and shade plants were produced in outdoor nursery rather than in container nursery. The results also showed that in Fukuoka, a major city in Kyushu that is adjacent to Korea, the planting rate of EBT, used as ornamental, gardening, and shade plants, was higher than that of deciduous broad-leaved trees and conifers. In the city, the planting rate of Cinnamomum camphora was the highest, Elaeocarpus sylvestris var. ellipticus, Ternstroemia gymnanthera, Ilex rotunda, Quercus glauca, Camellia sasanqua, Eurya emarginata, Pittosporum tobira, Raphiolepis indica var. umbellata, Hedera rhombea, Kadsura japonica, Trachelospermum asiaticum var. asiaticum. These species were verified in Kyushu area for their application as landscape trees and are expected to serve as landscape trees in Korea if the planting areas of them are expanded by global warming, urban heat island and regional microclimate.

Ginkgo trees have long been planted in Korea as roadside trees and ornamental trees, but the wood was seldom used except some utilization f3r small artifacts. Soaring prices of imported wood and future uncertainty about long-term supply of foreign woods have stimulated research on value-added utilization of less-utilized domestic wood resources such as Ginkgo wood. The processing properties of Ginkgo wood were investigated to determine its utilization potential in this study, and the results of treatability, drying characteristics, gluability, paintability, bending properties, chemical discoloration characteristics were presented.

네 종의 관상수목에서 흰가루병이 발생하였는데, 이들은 지금까지 한국에서 보고되지 않았으므로 발병양상을 기록하고 병원균을 동정하였다. 노린재나무 흰가루병은 그늘에서 자란 잎에서만 약하게 발생하였으므로 그리 문제되지는 않을 것으로 생각되는데, 병원균은 Microsphaera nomurae U. Braun으로 동정되었다. 꽃산딸나무 흰가루병은 그리 심하지 않았으나 묘포에서의 대발생이 우려되었는데, 병원균은 Microsphaera pulchra Cooke & Peck으로 동정되었다. 야광나무 흰가루병은 묘포에서 어린잎과 어린줄기에 주로 발생하였는데, 병원균은 Podosphaera leucotricha (Ellis & Everh.) Salmon으로 동정되었다. 왕느릅나무 흰가루병은 주로 가을철에 발생하였으며 2차 생장한 어린 가지에서 특히 심하였는데, 병원균은 Uncinula kenjiana Homma로 동정되었다.
