  • 이 연구는 고추씨가 첨가된 된장의 이화학 및 관능적 품질을 조사하였다. 수분함량은 된장 제조 직후 52.03-53.79%에서 발효가 진행됨에 따라 감소하였고, 염도는 13.28-14.05%에서 발효가 진행됨에 따라 큰 변화를 보이지 않았다. pH는 숙성이 진행됨에 따라 서서히 감소하는 경향을 보였고 고추씨 첨가량에 따라 유의적인 차이를 보이지 않은 반면 적성산도는 발효기간이 증가함에 따라 점차 증가하였고, 고추씨 첨가구가 대조구보다 높은 적정 산도를 보였다. 된장의 색도는 발효가 진행됨에 따라 L값과 b값은 약간 감소하고 a값은 약간 증가하는 경향을 보였는데, 전반적으로 고추씨 첨가량이 많을수록 적색도(+)를 나타내는 a와 황색도(+)를 나타내는 b값과 밝기를 나타내는 L값이 약간 높게 나타났다. 또 아미노태 질소 함량은 된장 제조 초기에 497-623 mg%에서 발효가 진행됨에 따라 서서히 증가하여 발효 120일에 대조구는 1,000 mg%이상, 고추씨 첨가구는 756-896 mg%로 증가하였다. 총 균수의 경우 제조 직후부터 발효 120일까지 고추씨 첨가에 관계없이 제조 직후에는 $10^7{\sim}10^8$ CFU/g의 총 균수에서 발효 진행되면서도 $10^7$ CFU/g을 유지한 반면 효모와 곰팡이 수는 $10^5$ CFU/g에서 $10^3{\sim}10^4$ CFU/g으로 감소하였다. 한편 된장의 관능검사 결과 고추씨의 첨가량에 관계없이 발효가 진행됨에 따라 된장의 고유 향미가 증가되었다.

  • The global warming by increased $CO_2$ will effect of plant pathogenic microorganisms and resistance of host plants, and it is expected to affect host-pathogen interactions. This study used Capsicum annuum L. and Xanthomonas euvesicatoria, a pathogenic bacteria of pepper, to investigate interactions between hosts and pathogens in a complex environment with increasedcultivation temperature and drought stress. As a result, the bacterial spot disease of C. annuum L. caused by X. euvesicatoria was $35^{\circ}C$ higher than $25^{\circ}C$. In addition, the effect on water potential on bacterial spot disease was much greater water potential -150 kPa than -30 kPa. The disease progress and severity higher than water potential -30 kPa. This result will useful for understanding interaction with red pepper and X. euvesicatoria under the complex environment with increased cultivation temperature and in water potential -150 kPa drought stress in the future.

  • 고추(Capsicum annuum)의 항산화 효과 및 생리활성 측정을 통하여 기능성식품의 소재로 활용하기 위한 기초 연구를 진행하였다. 폴리페놀 함량은 과육보다는 씨에서 높게 나타났다. 그러나 플라보노이드 함량은 풋고추 과육에서 높은 함량을 보였다. DPPH radical 소거활성에서 $SC_{50}$값은 홍고추 씨 $1,935{\pm}162\;{\mu}g\;DM/mL$, ABTS radical 소거활성에서는 $SC_{50}$값이 풋고추 씨 $3,354{\pm}76\;{\mu}g\;DM/mL$로 과육에 비해 높았다. 최종당화산물(AGEs) 생성 억제활성은 풋고추와 홍고추 씨, 풋고추와 홍고추 과육 순으로, ${\alpha}$-glucosidase 저해활성은 풋고추 과육, 홍고추 씨, 홍고추 과육, 풋고추 씨 순이었다. Tyrosinase 억제활성은 홍고추와 풋고추 씨, 홍고추와 풋고추 과육 순이었다. 종합해보면 기능성식품 소재로서 홍고추 씨 및 풋고추 씨가 과육보다 활용도가 높은 것으로 결론지을 수 있다.

  • Plant growth-promoting effects of rhizobacterial inoculation obtained in pot experiments cannot always be dependably reproduced in fields. In this study, we investigated the effect of inoculation with Azospirillum brasilense and Methylobacterium oryzae, which have displayed growth promoting effects in several pot experiments, on growth and fruit yield of red pepper under field condition in a plastic-film house. Four rows spaced 90 cm apart were prepared after application of compost ($10Mg\;ha^{-1}$), and red pepper seedlings (Capsicum annum L., Nocgwang) were transplanted in each row with 40-cm space. Experimental treatments were consisted of A. brasilense CW903 inoculation, M. oryzae CBMB20 inoculation, and uninoculated control. Twelve plots, 10 plants per plot, were allotted to the three treatments with four replicates in a completely randomized design. At the time of transplanting, 50 mL of each inoculum ($1{\times}10^8cells\;mL^{-1}$) was introduced into root zone soil of each plant, and re-inoculated at 7 and 14 days after transplant. Plant growth and fruit yield were measured during the experiment. Both A. brasilense CW903 and M. oryzae CBMB20 could not promote growth of red pepper plants. All growth parameters measured were not significantly different among treatments. There were large variations in fruit yield recorded on plot basis, and no statistically significant differences were found among treatments. The failure to demonstrate the expected plant growth promoting effect of the inoculants is possibly due to various environmental factors, including weather and soil characteristics, reducing the possibility to express the potential of the inoculated bacterial strains.

  • Total iron content and ferritin distribution have been determined in red pepper(Capsicum annuum L.) during development stage under conditions of iron nutritional status from hydroponic culture. Color of the leaves become chlorotic on iron deficient and high concentration. The plant height on each iron concentration had retarding effect at concentration lower than $25\muM$ and greater than 125$25\muM$. In normal green leaves. Total iron content was almost constant with a mean value of $2.5\mumole$ of iron/mg of dry matter, except at 63day, for which it increases slightly to $4\mumole$. Howere, iron content of chlorotic plants grew on iron free medium was not almost detectable. Also in post chlorotic leaves(++Fe), iron content was evidently increase unitl 7days after transfer on liquid medium, but decreased from after 14days. Also, ferritin protein analysed total protein extracts prepared from leaves of different ages using antibodies raised against ferritin protein. Ferritin protein deereased progressively during the first week of germination and was not detectable in vegetative tissues. Ferritin protein in post chlorotic leaves wasevidently strongly cnhanced until 11days after transfer on liquid medium but decreased until the leves became chlorotic.
