This study was performed to abtain the physicochemical characteristics of wood for effective bonsai material production. Three species of of bonsai material were Lagersroemia indica, Acer buergerianum, Ligstrum obtusifolium. Chemical component included lignin, holocellulose, organic solvent extractives and ash were analyzed. Mechanical properties determined were modulus of elasticity(MOE), modulus of rupture(MOR) and deflection. The results obtained from this study indicated that holocellulose content plays a very important part in bonsai material. Decrease of MOE facilited in bending test of bonsai material. In the other side, increase of MOR also influenced on bonsai material.

This study was carried out to estimate the effects of aerial applications of fenitrothion on arthropod communities in pine forests. Since 1988 the applications have been conducted in Busan and Gyeongsangnam-province to control Monochamus alternatus Hope, a vector of the pine wilt disease, Bursapelenchus xylophilus (Steiner 81 Buhrer) Nickle. Abundance, species richness and community structure of arthropods in crown, undergrowth and ground of pine forests were compared between the aerial-sprayed and un-sprayed sites in the 4 regions in Busan and Gyeongsannam-province of Korea. The pesticide aerial applications did not make any significant influences on the abundances (No. individuals per sample) and taxon composition of arthropods, whereas it made some effects on species diversity. Arthropod richness (no. species per site) in undergrowth was lower in long-term pesticide applied sites than in short-term applied sites, whereas P-diversity (heterogeneity of species) of arthropod communities in ground was lower in pesticide-treated sites than in untreated sites.

These findings introduced in this article are deemed to be very closely connected to ethnobotany. This article is the “Chomokhwahuei”, included in the [Dongyu Diary] which was written by Song Ju Sang (1695-1751) from the late Chosun Era. The [Dongyu Diary] by Song Ju Sang is a writing in diary format which records the sightseeing of the Geumgang Mountain, specifically recording the peculiarities of the plants observed which are included in a separate section called “Chomokhwahuei”. In this section, the place of observation and the name and characteristics of the plants are recorded. Although it is a short recording of merely 2 pages, it is credited for its unusual recording of vegetation in the Geumgang Mountain area and deemed to be useful for ethnobotanical studies. With this article, we are able to roughly study the vegetation and its dispersion 260 years ago in the Geumgang Mountain area of the Chosun era and discover the binomial nomenclature of the plants then, not to mention the way the people back in this ear observed their plants. However, it is difficult to comprehend this article because it was written in cursive characters. In this document, the author and his bibliography are to be briefly reviewed and we will review the plant species and discuss the value of the article “Chomokhwaheui”, as the original text will be translated. We hope the information of the old plant names learned through this study will contribute to an accurate interpretation of the plant name discovered in the old text and their ethonobotanical utilization.

This study was conducted to investigate the effects of host tree species, temperature and humidity on ex vitro for seed germination in endangered species of Loranthus tanakae. In addition, we compared seed shapes between Loranthus tanakae and Viscum album that we could have easily shown in ex vitro condition. Seeds were germinated after one week inoculation and followed to develop radicles. Seed germination rates of Loranthus tanakae were 80~95% in most of the experimental conditions. The highest rate of holdfast penetrated to host plants was 72% in Populus alba var. pyramidalis among 13 different species tested at 20oC. Also the rates of their penetration were 57% in Morus bombycis, 55% in Acer palmatum and 42% in Castanea crenata at 20℃. Seeds were germinated under condition without irrigation and followed to withered in 12 weeks later. Stages of seed germination of the Loranthus tanakae were followed by radicle induction, holdfast development, haustorium formation and penetration in order in total period of 14 weeks.

본 연구에서는 벽면녹화시스템에 식재된 사초류의 방위(광도)에 따른 생육반응 및 옥상녹화시스템에 식재된 사초류의 토양깊이에 따른 생육차이 등을 조사하고자 하였으며, 사초류가 다양한 형태로 활용될 수 있도록 기초적인 자료들을 제시하고자 하였다. 벽면녹화 및 일반컨테이너의 온도변화를 비교한 결과, 벽면녹화의 경우 온도가 낮아지는 것을 알 수 있었고, 주로 화창한 날씨가 유지된 8~9월 동안에 차이가 뚜렷하였다. 테스타시아사초, 에버골드 및 털대사초 등은 높은 광도에서 생육이 우수하고(0~1799㎛ㆍm?²ㆍs?¹), 상록갈사초, 줄무늬사초, 대사초 및 흰줄무늬실사초는 낮은 광도에 적합한 것으로 판단되었다(0~786㎛ㆍm?²ㆍs?¹). 광도가 낮을수록 식물의 색이 선명해져 관상가치가 증가하였는데, 본 연구에서는 무늬의 변화에 대한 고려가 이루어지지 않아 추가적인 연구가 이루어져야 할 것으로 사료되었다. 토양깊이별 수분함량은 10㎝의 경우 배수층 없이 혼합용토로만 이루어져 높게 유지되는 것으로 나타났고, 대부분의 사초류들도 10㎝ 깊이에서 생육이 좋았다. 에버골드, 대사초 및 테사타시아사초 등은 토양깊이 20㎝에서 생육이 우수하였다. 흰줄무늬 실사초와 털대사초 노란무늬종은 토양깊이 40㎝에서 생육이 좋은 것으로 나타났다. 본 연구에서는 사초류가 10~20㎝의 낮은 토심에서도 생육이 우수하여 옥상녹화 소재로 충분히 도입 가능할 것으로 판단되었다. This study was carried out to investigate the plant growth of several Carex L. plants according to light intensity and soil depth planted on a green wall and roof, and to show basic data for the use of Carex L. plants in various forms. The temperature was dropt more in the green container compared to the normal especially during the genial weather from August to September. The plant growth of Carex testaceae, Carex oshi-mensis Evergold, and Carex ciliatomarginata Nakai was excellent at light intensity from 0 to 1799 ㎛ㆍm?²ㆍs?¹, and that of Carex siderosticta Hance, Carex flagellifera Bronzita, Carex ornithopoda Variegata, and Carex morrowii Ice Dance were best in lower light intensity from 0 to 786 ㎛ㆍm?²ㆍs?¹. The leaf color of the plants changed vividly as the light intensity grew lower and the visible value of the plants increased. There must be more considerations about the pattern changes in additory experiments. The water content in the soil depth of 10 ㎝ was maintained higher than the other treatments because of no drainage layer. Most Carex L. plants grew excellent in the soil depth of 10 ern, However, Carex oshimensis Evergold, Carex sid-erosticta Hance, and Carex testaceae showed the best plant growth in soil depth 20 ㎝, and Carex morrowii Ice Dance and Carex ciliatomarginata Nakai in soil depth of 40 ㎝. Therefore, Carex L. plants could be recommended as materials for green roof because they also grew well in light soil depth of 10~20 ㎝.

본 실험에서는 차광 및 시비처리에 따른 여러 양치류의 생육반응을 구명하여 양치류의 효율적인 재배관리를 위한 광도 및 영양관리에 대한 기초자료를 제시하고자 하였다. 상록성 양치류인 참지네고사리, 도깨비고비, 선바위고사리 등은 차광수준 30~60%에서 생육이 우수한 것으로 나타났다. 이들은 시비량이 많을 수록 생육이 좋아졌으며, 식물의 생육 및 생존율은 전처리구에서 유지되었다. 이들은 적합한 차광수준에서 시비할 경우 식물의 관상가치가 높아지고(엽색 변화) 생육도 향상되었다. 하록성 양치류인 설설고사리는 차광수준 30~60%, 참새발고사리는 60%, 그리고 개고사리는 0~30%에서 생육이 우수한 것으로 나타났다. 이 들은 시비에 의한 효과는 부분적으로 보였으나, 일부 차광 처리구에서는 시비함에 따라 생존율이 감소하였다. 또한 이들은 모든 처리구에서 생장량도 감소하는 경향을 보여, 생육관리가 쉽지 않은 식물로 판단되었다. 시비 및 광도에 따른 상록성 및 허록성 양치류의 생육반응에 차이를 보였다. This study was carried out to investigate the plant growth of various ferns affected by the shading and fertilizer application and to recommend the appropriate levels of light intensity. Evergreen ferns like Dryopteris nipponensis Koidz., Cyrtomium falcatum (L. f.) Presl, Onychium japonicum (Thunb.) Kunze and deciduous ferns like Athyrium niponicum (Mett.) Hence, Thelypteris decursive-pinnata Ching, Athyrium brevifrons Kodama ex Nakai were used in this experiment. Evergreen ferns showed the best growth in the shading level of 30~60%. The plant growth and ornamental value (leaf color) of these plants were improved according to the fertilizer application in appropriate shading levels. The survival rate remained constantly in all treatments. Deciduous ferns showed the best growth in different shading levels from 0 to 60%. Some treatments showed improved growth according to fertilizer application, whereas survival rate was in the other treatments. There were differences in plant growth of evergreen and deciduous ferns according to fertilizer application, and additional researches must be executed to explain these reponses.
