  • This study was conducted to investigte the visual preference and response between introduced and native trees for utilization of the south native trees in interior space. 1. The intensity of illumination was below 500lux at 24 buildings of interior spaces surveyed. Generally the temperature was 24~$26^{\circ}C$, and humidity was 60~70%. 2. Total number of introduced tree species were 9 familiar, 16 genus, 18 species, especially palm genus were the largest tree among them at these surveyed interior spaces, but native trees were only 2 species. The introduced tree of 2 to 3m in height was 46 percent, and the case of 1.2 to 2m was 42 percent. 3. The mean of visual preference was the highest at Rhapis excelsa and howeia belmoreana, and followed with Neolitsea sericea, Daphniphllum macropodum, Listsea japonicum. In the mean of visual preference for selected tree groups, native tree was not different as compared with introduced tree. 4. Visual image factor of the native and introduced trees at interior spaces was classified by individual factor and emotional factor. These 2 factors were shown 66.5% total variance. The native tree was strongly recognized on individual factor, as , and introduced tree was also strongly recognized on emotional factor. 5. In the analysis of visual preference and image, a difference between the selected groups of the introduced and native trees were not shown significant, and the introduced trees were similar to the native trees on the visual image. This result was as follow There was an analogy between Cinnamomum camphora, Ligustrum japonicum and Ficus retusa, Ficus benjamina. There is an analogy between Castanopsis cuspidata var. sieboldii, Cinnamomum japonicum and Ficus retusa, Ficus benjamina. There was an analogy between Elaeocarpus sylvestris var. ellipticus, Fatsia japonica and Rhapis excelsa, Howeia belmoreana. There was an analogy between Neolitsea sericea, Daphniphyllum macropo여, Listsea japonica and Rhapis excelsa, Howeia belmoreana. There was an analogy between Elaeocarpus sylvestris var. ellipticus, Fatsia japonica and Dracaena fragranse, Ficus elastica, Monstera deliciosa.

  • 제주 재래마와 쓰시마 재래마 간의 유전적 유연관계를 16개 혈액 단백질 좌위의 유전적 다형현상을 분석하여 연구하였다. 두 지역의 재래마 집단에서 5개의 단백질 좌위를 제외한 11개 좌위에서는 유전적 다형현상을 보였다. 다형현상을 나타내는 좌위에서 분석된 유전자 빈도를 이용하여 평균 이형접합자 빈도를 분석한 결과 제주 재래마에서는 0.375로 쓰시마 재래마의 0.304 보다 다소 높게 나타났다. Nei방법에 의해 계산된 Da distance와 유전자 동일성은 각각 0.108과 0.868이었다. 본 연구결과와 이미 보고된 아메리카말 집단들에서의 결과를 이용하여 phylogenetic tree를 구성하여 본 결과 크게 세 개의 cluster를 이루었다. 즉 아메리카말 집단들이 하나의 cluster를 이루었고 제주 재래마 집단이 하나의 cluster를 이루었으며, 이 두 cluster는 현존 말의 기원으로 보는 몽고 야생마 cluster에서 분지됨을 알 수 있었다.

  • With continuous decline of Philippine forest cover, sustainable forest management and restoration are essential to restore destroyed forest ecosystems. Unfortunately, of ten most planted trees in reforestation projects in the Philippines, eight are exotic species, with large leaf mahogany (Swietenia macrophylla) being the most dominant. In this study, effect of Swietenia macrophylla in reforestation projects on native tree species was evaluated. Effects of S. macrophylla leaf litter, frequency, and canopy closure on the growth of the Philippine native species Pterocarpus indicus were investigated. Results showed that S. macrophylla leaf litter significantly inhibited the growth of P. indicus seedlings based on root collar-to-shoot height. The standardized growth rate of seedlings in plots without S. macrophylla leaf litter was significantly higher than the growth rate of seedlings in plots with leaf litter. Furthermore, there was no significant difference in the standardized growth rate of seedlings between plots without leaf litter and a control plot. On the contrary, S. macrophylla tree frequency and canopy closure showed no significant effect. These results attest to the negative effect of widely planted S. macrophylla to a valuable Philippine native tree P. indicus. With accumulating scientific evidence about negative effects of S. macrophylla on native trees, discontinued use in tree planting and reforestation efforts with active management of restoration sites previously planted with large leaf mahogany are needed.

  • This study was conducted to analysis the ecological characteristics of "Wando HolIy"$(llex{\times}wandoensis)$ which is expecting as a possible ornamental tree with its beautiful leaves, flowers and fruits, and to find special breeding material which have particular characteristics and also provide correct environmental information which are required for commercial cultivation. The hill of Galmoon-Ri, Gunoei-Myon, Jeonnam Province, Korea, were reported as a original habitat of native $llex{\times}wandoensis$. The investigation shows that soil pH of native habitat was 6.18, hardness was 2.39, humidity was 38.6%, direction of slope is SSW, and average inclination was $15^{\circ}. The vegetation around $I.{\times}wandoensis$ is occupied by trees like an Quercus variabilis, Q. serrata, Q. acuta and so on. These are mixed forest of deciduous trees. Tree height reached up to about 12m and its coverage is about 30%. Q. salicina, Camellia japonica, I. integra, Cryptomeria japonica account for sub-tree layer. Tree height is around 8m and coverage is about 20%. Shrub layer was taken by Viburnum furcatum, Callicarpa japonica, Styrax japonica, Eurya japonica, Lindera obtusiloba, Ligustrum japonicum, Smilax china, Cornus walteri etc. Tree height reaches around l.2m and coverage is around 20%. Herb layer includes Trachelospermum asiaticum var. intermedium, Cymbidium goeringii, Dryopteris bissetiana, Disporum viridescens, Disporum smilacinum, Sasa borealis var. gracilis etc. Trachelospermum asiaticum var. intermedium, which are observed in southern evergreen zone, are dominant and its coverage is around 20%. The native habitat was in spoiled condition because of artificial thin out.

  • Seeding treatment was used for 2 years at an artificial bare ground for selecting tree species suitable for forest-floor revegetation. 2 ${\times}$2${\times}$2 factorial experiment was used with a randomized complete block design for 19 native tree species and results were summarized as follows; 1. Native species suitable for restoration of bareland under 75% shading in central part of Korea were Styrax japonica, Styrax obassia, Smilax china, Callicarpa japonica, Stephanandra incisa, Viburnum dilatatum for. pilosulm, Magnolia sieboldii, Cornus kousa, Celastrus orbiculata, etc.. Especially, Magnolia sieboldii, Stephanandra incisa and Stryrax obassia were tolerant for forest-floor with hardened woil surface and Callicarpa japonica, Viburnum dilatatum for. pilosulum, Euonymus sieboldianus and Philadelphus schrenkii were suitable for softened soil surface with straw-mat mulching. 2. It is necessary to break seed dormancy to accelerate germination in case of Styrax obassia, Styrax japonica, Viburnum dilatatum for. pilosulum, Smilax china and Stephanandra incisa.
