The seedling height, leaf width and leaf length of pepper increased in plants grown from seeds irradiated with the low dose of 4 Gy. The $O_2$ evolution in the 4 Gy irradiation group was 1.5 times greater than the control. Pmax was decreased with increasing illumination time by 20% in the control, while hardly decreased in the 4 Gy irradiation group. Fv/Fm was decreased with increasing illumination time by 50% after 4 hours, while Fv/Fm in the 4 Gy irradiation group was decreased by 37% of inhibition, indicating that the low dose $\gamma$ radiation increased resistance of plants to photoinhibition.

The aim of this study is to look at how pepper was used in traditional medicine. In other words, this study aims to take a look at the process by which the medicinal nature & efficacy of pepper in traditional society was perceived and arranged through the aspects of the use of pepper as an exotic crop for treating diseases. This study investigated cases of using pepper for medical treatments by referring to books on traditional medicine in Korea. The old records about pepper are mainly in empirical medical books from the late Chosun dynasty. Nevertheless, the records about pepper tend to decrease in medical text as time goes by. Such a phenomenon can be attributable to the fact that people began to use pepper for daily food life rather than for medicinal purposes. Pepper was used mostly for digestive trouble such as vomiting, diarrhea, and stomachaches, and it was also applied to mental and aching diseases caused by the sound of body fluids remaining in the stomach. In addition, there were many cases where pepper was used externally for surgical disorders. Such symptoms for treatment are linked to, or in a complementary relationship with, research results in modern times. Boiled pepper was generally taken in the traditional herbal decoction method, and in the case of surgical diseases, it was applied externally. The cases of using old pepper, using pepper with seeds or without seeds, and using pepper mixed with sesame oil belong to a sort of herbal medicine processing, which usually aimed at changing the medicinal nature of pepper. In addition, in relation to the eating habits at that time, pepper was used as seasoning and to make red pepper paste with or without vinegar. There are two words used for pepper in the medical textbooks, 苦椒 (gocho) and 烈棗 (yeoljo). These words are translated into Korean as gochu, so we can identify this word as a nickname for pepper.

Four seed vetch (Vicia tetrasperma), a biennial native leguminous plant, was used for a cover crop with different quantity of sowed seeds. Weed suppression and yield were evaluated for the red pepper cultivation in the following year of the vetch seeding. Seeding of 1.0, 2.0, 3.0, 4.5, and 6.0 kg 10 $a^{-1}$ suppressed weed occurrences until late in the growing season of the red pepper. Consequently, red pepper in the cover cropping system with seeding of 3.0, 4.5, and 6.0 kg 10 $a^{-1}$ had a similar yield to the conventional red pepper. The ideal seed rate in four seed vetch was 3.0 and 4.5 kg 10 $a^{-1}$ in terms of reducing weed occurrence as well as increasing growth and yield in red pepper.

This study was conducted to investigate the effects of osmotic priming, liquid smoke (LS), sonication and modified drum priming treatments to improve the germination speed and uniformity of pepper seeds for high quality export seeds. Seeds were treated in 0.5, 1.0, 5.0, 10% LS solution only or with 100mM $K_2SO_4$ solution for 6days at $15^{\circ}C$. Sonication treatment was performed for 5, 10, and 20 minutes at an intensity of 5.2, 10.4, 15.7, 21.0, 26.1kHz in water at $15^{\circ}C$. After sonication treatment, seeds were primed with water or 100mM $K_2SO_4$ for 4days. 40, 50 and 60% seed moisture content (SMC) of hydrated seeds were incubated for 84, 96 and 108h in a container with a relative humidity of 99% at 26rpm for a modified drum priming treatments. 0.5% LS treatment with water or 100mM $K_2SO_4$ priming showed significant effects with 71% GP (9.0days MGT) and 66% GP (7.4days MGT), respective, while untreated seeds resulted in only 61% GP and 10days MGT. The healthy seed % was increased by 24% by $K_2SO_4$ priming with LS treatment compared to untreated seeds. However, sonication treatment showed less germination or no difference compared to untreated seed, regardless of intensity and treatment time. The modified drum priming treatment (108h incubation after 50% SMC hydration) significantly improved the GP (on the $4^{th}$days after sowing), germination rate (GR), and MGT to 65%, $28%{\cdot}day^{-1}$, and 3.6days, whereas untreated seed resulted only 7% GP, $17%{\cdot}day^{-1}$ GR and 5.9days MGT. Thus, modified drum priming treatment effectively improved seed germination and is considered as an industrially promising treatment methods considering the shortening of the treatment period and environment-friendly aspects.

A rapid radicle assay for prescreening antagonistic bacteria to Phytophthora capsic4 causal agent of Phytophthora blight of pepper was developed. Sixty-four bacterial strains with in vitro antifungal activity selected out of 1,400 strains isolated from soils of Ansung, Chunan, Koyang, and Paju, Korea in 1998 were used for development of the bioassay. Uniformly germinated pepper seeds dipped in bacterial cells for 3 hours were placed near the edges of growing mycelia of P. capsici on water agar containing 0.02% glucose. Five-week-old pepper plants(cv. Nockwang) were inoculated to compare with results of the radicle assay developed in this study. For plant inoculation, pepper seeds were sown in potting mixtures incorporated with the bacterial strains, then transplanted into steam-sterilized soils 3 weeks later. Plants were hole-inoculated with zoospores of P. capsici 2 weeks after transplanting. Disease incidence and severity were determined in radicle and plant assessments, respectively. In radicle assay, six strains, GK-B15, GK-B25, OA-B26, OA-B36, PK-B09, and VK-B14 consistently showed the significant(P=0.05) disease reduction against radicle infection by the fungus, four of which also did in plant assessments. Strains OA-B36 and GK-B15 consistently reduced the fungal infection in both the radicle assay and the plant assessment. Therefore, prescreening strains using the radicle assay developed in this study followed by plant assay could reduce time and labor, and improved the possibility of selecting antagonistic bacteria for control of Phytophthora blight of peppers.

Sixteen seed samples of nine vegetable crops imported from Japan were tested for plant quarantine by routine methods of seed health testing. Nineteen species of fungi including Alternara alternata were identified from the seed samples. Some species were very frequently detected in the seeds. In this experiment, Verticillium albo-atrum, V. dahliae and Macrophomina sp. from the seeds of spinach, and Cercospora capsici, Drechslera hawaiiensis and V. albo-atrum from the seeds of sweet pepper were detected for the first time, respectively. It has been reported that they had a pathogenicity on some vegetable crops in Japan and other countries. The data suggest that an epidemic damage may be occurred if the infected seeds are sown and cultivated in Korea.

본 연구에서는 고추씨 에탄올추출물이 콜레스테롤 흡착능 및 UDP-glucuronyl transferase 활성에 미치는 영향을 관찰하였다. In vitro 콜레스테롤 흡착능에서는 대조군에 비해 고추씨 에탄올추출물 모든 농도에서 유의적으로 증가하였다. In vivo에서 실험동물은 체중 $100{\pm}10$ g 내외의 Sprague-Dawley계 수컷 흰쥐를 사용하였으며, 실험군은 정상식이를 공급한 정상군과 고지방 고콜레스테롤 식이 실험군으로 나누고 고지방 고콜레스테롤 실험군을 다시 고추씨 에탄올추출물을 공급하지 않은 군(HF groups), 0.1% 공급한 군(HEA group), 0.2%을 공급한 군(HEB group) 및 0.5%을 공급한 군(HEC group), 5군으로 나누고 각 군당 8마리씩 3주간 사육하였다. 체중증가량은 정상군에 비해 HF 군에서 유의적으로 증가하였고 고추씨 에탄올추출물을 공급한 모든 군에서 HF 군에 감소하였으나 유의적인 차이는 없었다. 식이효율은 고추씨 에탄올추출물을 각각 0.1%, 0.2% 및 0.5% 공급한 군에서는 HF군에 비해 유의적이지는 않았지만 감소하는 경향을 보였다. 간조직의 총콜레스테롤 및 중성지질 함량은 정상군에 비해 HF 군에서 유의적으로 증가하였고 HF 군에 비해 HEA, HEB 및 HEC군에서는 유의적이지는 않았지만 다소 감소하는 경향을 나타내었다. UDP-glucuronyl transferase 활성에서는 정상군에 비해 HF 군에서 증가되었고, 고추씨 에탄올추출물 공급군인 HEC 군에서는 HF 군에 비해 유의적으로 증가되어 가장 높은 활성을 나타내었다. 혈청중의 총콜레스테롤 및 중성지방 농도는 정상군에 비해 HF 군에서 유의적으로 증가하였고, HEA, HEB 및 HEC 군에서 HF 군에 비해 감소하였다. HDL-콜레스테롤은 정상군에 비해 HF 군에서 유의적으로 감소하였으나 HEA, HEB 및 HEC 군에서는 HF 군에 비해 정상군 수준으로 증가하는 경향을 보였다. 반면, LDL-콜레스테롤은 HF 군에서 정상군에 비해 유의적으로 증가하였으나 HEA, HEB 및 HEC 군에서는 모두 유의적 감소를 나타내었다. 대변중의 총콜레스테롤 함량은 정상군에 비해 HF 군에서 유의적으로 증가하였고 HF 군에 비해 특히 고추씨 에탄올추출물 공급군 HEB 군 및 HEC 군에서 증가하는 경향을 나타내었으나 유의적인 차이는 없었다. 중성지질 함량은 정상군에 비해 HF 군에서는 유의적이지는 않았지만 증가되었고, 고추씨 에탄올추출물을 공급한 HEB군 및 HEC 군에서 HF 군에 비해 다소 증가하는 경향을 나타내었다. 따라서 고추씨 에탄올 추출물은 콜레스테롤 흡착능에서 효과적으로 작용하였으며 고지방 고콜레스테롤 식이 흰쥐의 UDP-glucuronyl transferase 활성 및 지질대사에 효과적으로 작용하였음을 규명하였다.

This experiment was conducted to study whether priming with deep sea water results in enhancement of seed germination and to identify the optimum concentration of the priming solution, and duration of priming using sweet pepper (Cv. California wonder), rice (Cv. Ilpum) and ginseng seed. Sweet pepper and rice seeds were primed with 5 various concentrations (5%, 10%, 15%, 20% and 30%) for deep sea water for 48 hours, 24 hours and 12 hours at $25^{\circ}C$ and ginseng seeds in 5%, 10%, 15%, 20%, 25% and 30%, and 2,4,6, and 8 electrical conductivity (EC) which were made by desalinating deep sea water. Priming in deep sea water (DSW) improved the early and final germination percentage, mean germinal on rate, emergence percentage and root and shoot length, compared with plain water, $KNO_3$ and without priming treatments. In sweet pepper, 24 hours priming with 5 percentage DSW significantly improved the early germination percentage and radical length. It has also improved the mean germination and emergence days and early emergence percentage, compared with $KNO_3$ and control. Whereas, in rice, 48 hours priming with 10 percent DSW significantly improved the early germination percentage, plumule emergence percentage, root length and shoot height. Hence the best seed priming treatment on sweet pepper and Rice are 24 hours with 5 percentage DSW and 48 hours with 10 percentage DSW, respectively, whereas in ginseng, priming with EC4, EC8 and 25% DSW had shown better germination.
