본 연구는 가축분뇨 액비와 양분을 조정한 맞춤액비의 관비처리가 시설 하우스 재배에서 가지 생육, 토양 화학성에 미치는 영향을 알아보기 위하여 수행되었다. 시험구처리는 가축분뇨액비(LM), 가축분뇨액비에 화학비료를 첨가한 양분조정 맞춤액비(LM+CF), 가축분뇨액비에 양분과 아인산 첨가 맞춤액비(LM+CF+PA) 처리구와 화학비료 관행처리구(CCF)를 두었다. 가지의 과장, 과폭, 과중은 LM 처리구가 LM+CF, LM+CF+PA 및 CCF 처리구에 비해 유의적으로 낮았다. LM+CF, LM+CF+PA 및 CCF 처리구 간에 과장, 과폭 및 과중의 유의적 차이는 나타나지 않았다. 가지 주당 수량은 CCF 처리구(27.9 kg)에 비하여 LM 처리구(26.2 kg)에서 6% 낮았다. 가지의 생체중은 CCF와 LM+CF 및 LM+CF+PA 간에 통계적으로 유의한 차이를 나타내지 않았다. 가지 주당 상품수량은 LM 처리구에서 가장 낮았으며, CCF 처리구(24.1 kg)에 비하여 LM+CF+PA 처리구(26.6 kg)에서 8% 증가하였다. 토양의 화학성은 CCF 처리구가 다른 처리구에 비하여 전반적으로 높은 경향이었다. 이상의 결과를 종합해 볼 때 화학비료의 관행시비에 비하여 가축분뇨 액비에 화학비료를 첨가한 맞춤액비에 의한 관비가 가지의 상품생산성 향상 및 토양의 화학성 개선에 유리한 시비방법으로 생각된다.

우리 나라에서의 연간 가지의 1인당 소비량은 100g 내외로 미비하지만, 일본에서는 1인당 약 2kg 내외로 소비하고 있다. 이러한 일본의 수요에 부응하여 우리나라에서는 계약재배 형태로 매년 일본에 수출이 증가되면서 재배면적이 증가되고 있다. 그러나 국내 가지의 생산성은 일본에 비해 크게 미치지 못하고 있는 실정이다. 이러한, 수출을 위한 가지는 재배시기가 동절기에 시설내에서 이루어져 저온과 일조부족과 같은 불량한 환경으로 인해 수량의 감소 및 품질의 저하를 가져온다. (중략)

Yellow spot or blotch symptoms were observed on the upper surface of eggplant (Solanum melongena. cv: Cheonryang) leaves in a commerical vinyl-house of Hapchon-gun, Kyongnam, Korea. We identified Leveillula taurica(L v.) Arnaud as a pathogen causing powdery mildew of eggplant which was observed newly in Korea. The fungal conidia from eggplant leaves were reinoculated to eggplant, tomato and pepper to confirm the same disease as the symptomatology and morphology of the pathogen.

A bacterial strain YB-70 which has powerful biocontrol activity against Fusarium solani causing plant root-rot resulting in considerable losses of many economical crops was isolated and selected from over 500 isolates from a ginseng rhizosphere in suppressive soil, and identified as a strain of Bacillus subtilis. In several biochemical and in vitro antibiosis tests on F. solani with culture filterates from B. subtilis YB-70, our data strongly indicated metabolites which mediated inhibition of the fungal growth were presumed to be heat-stable, micromolecular, and ethyl alcohol solutable antifungal substances. Suppression of root-rot by B. subtilis YB-70 was demonstrated in pot trials with eggplant (Solanum melongena L) seedlings. Treatment of the seedling with the bacterial suspension (1.7~1.9$\times$$10^5$ CFU/g) in F. solani-infested soil significantly reduced disease incidences by 68 to 76% after 25 to 30 days. The results supported that B. subtilis YB-70 have excellent potentials as a biocontrol agent.

본 연구에서는 총 페놀성 화합물 함량(2,465 mg/100 g)을 나타낸 가지 외피 에탄올 추출물의 in vitro 항산화 및 미백 효과를 알아보기 위해 다양한 연구를 진행하였다. 가지 외피 에탄올 추출물의 ABTS radical 소거활성과 FRAP assay결과 농도 의존적인 항산화 활성이 나타났으며 더불어 높은 세포 지질 과산화 억제활성을 보여주었다. 또한 가지 외피 에탄올 추출물의 자외선 흡수도를 측정한 결과 UV-A(320-400 nm)와 UV-B(290-320 nm)영역을 일정 수준 이상의 흡수 경향을 나타냈으며, 특히 UV-B(290-320 nm)영역에서 높은 흡수도를 보여주었다. 최종적으로, 미백효능을 알아보기 위해 mushroom tyrosinase 및 세포 내 멜라닌 함량 저해효과를 측정한 결과 모두 농도 의존적인 저해 효과를 보여주었다. 결국 본 연구결과를 종합해 볼 때 chlorogenic acid를 포함하여 다양한 페놀성 화합물을 함유한 가지 외피 에탄올 추출물은 in vitro 항산화 및 미백 효과를 가지는 기능성화장품 소재로서의 활용 가능성이 있을 것으로 판단된다.

A scab disease on eggplant (Solanum melongena L. cv. Chukyang) in plastic film houses around Kimhae area in Korea during the winter season of 0998-1999. The disease started on leaves with small dark brown spots which were gradually expanded to 1 to 3 mm diameter lesions. Later, the central parts of the lesions became collapsed and detached to make holes. Dark brown mold was grown out of the lesions on the lower side of leaf. Numerous conidia were produced on the lower side of leaf. Numerous conidia were produced on the diseased leaves and appeared to be readily dispersed in the air. A fungus was isolated from the diseased leaves, and tested for Koch's postulates to prove the causal agent of the desease. The isolated fungus grew on potato dextrose agar, forming greenish black to pale brown colonies. Conidia were ellipsoidal, fusiform or subspherical, mostly one-celled but occasionally septated, and formed in long branched chains on the erected conidiophores which were pale olevaceous brown and variable in length between 12.4 and $393.4\mu\textrm{g}$. The fungus was identified as Cladosporium cucumerinum Ellis Arthur based on the above morphological characteristics examined. The optimum temperature for mycelial growth and conidial formation was about 20 to $25^{\circ}$. In addition to cucumber, the fungus was also pathogenic to watermelon, pumpkin and oriental melon. This is the first report on the scab disease of eggplant in Korea.

In order to establish a fully automatized pest control in the a greenhouse , the authors developed a prototype of microcomputer installed spraying vehicle which traveled along the furrows. Since a power sprayer mounted on the vehicle was driven by gasoline engine, plants grown in the greenhouse might be injured by the gas exhausted from the engine. Thus , effects of exhausted gas on photosynthetic rate and the shedding of flowers and buds of plants were examined. At first, effects of exhausted gas on photosynthetic rate of potted sweet pepper (Capsicum annuum L.) and eggplant(Solanum melongena L.) plants were examined. In a closed vinyl house the engine was operated for 5 minutes and plants were exposed to the gas for 2hours in the daytime on a fine day. Photosynthetic rate did not significantly decreased by the treatment in both species. Secondly, effects of ehtylene on the shedding of flowers and buds of sesame (Sesamum indicum L. ) were examined. In the closed and partiall opened vinyl house, the engine was operated for 5 minutes and potted sesame plants were exposed to the gas for 12 hours in the night. In partially opened vinyl house, ethylene concentration decreased to 0 ppm 3 hours after the engine was stopped and flower and bud did not shed. In contrast, when vinyl house was closed ethylene concentration was 0.75 pm even 12 hours after the engine was stopped and flowers and buds shed markedly and epinasty was observed in upper young leaves. As mentioned above , it was revealed that injury of plants in the greenhouse caused by the gas exhausted from a gasoline engine could be prevented by providing suitable ventilation.

Induction of somatic embryogenesis from Brazilian eggplant variety F-100 was studied in response to four auxin types. NAA, at the optimal concentration of 54 $\mu\textrm{m}$, was the only one that resulted in the induction of somatic embryos in either leaf and cotyledon explant and, at murk lower intensity and frequency, in hypocotyl and epicotyl explants. The optimal temperatures for embryo induction were 28 and 35$^{\circ}C$ for cotyledon and leaf explants. Incubation at 22$^{\circ}C$ caused a significant reduction both in the frequency and intensity of induction. This system was used to study the effects of position and orientation of the tissue on the culture medium as well as of antibiotics and explant co-cultivation with Agrobacterium on the efficiency of somatic embryo induction. The intensity of embryo induction was greater in the midsections of cotyledons relative to apical and basal regions, when the abaxial surface was in contact with the culture medium. The presence of antibiotics resulted in approximately 40-60% reduction of embryo induction relative to control explants, which originated 335$\pm$26.6 embryos. Co-cultivation with Agrobacterium before treatment with antibiotics caused a more drastic reduction (80-99%). Ampicilin treatment after cocultivalion with Agrobacterium caused the least inhibitory effect, allowing the production of 60 embryos/explant.
