  • Forage barley was developed for decreasing the import of forages, and increasing the farmer' income about ten years ago. Nevertheless of higher of farmer' income, the forage barley' area is slowly increased because of lacking of barely seeds. In order to suggest the plan of the urgent spreading on forage barley, the seed-gathering of forage barley was cultivated on 14-provinces and 291ha on 2009. The cultivation area of kyeungnam, kyeungbuk and chunnam province was more than other provence. The youngyang cultivar was cultivated more than orher cultivar. Seed-gathering amount of Youngyang, Uhoo and Yooyun cultiva was 364,213 and 303MT respectively. There were several problems for seed-gathering of forage barley which were the delay of seeding time and the more seeding amount, and the higher seed drying temperature than that of standard manual.

  • This experiment was conducted to obtained basical source for gathering seeds in flue- cured (NC 2326), and to investigate some characters on the relation to gathering number of capsules per a plant; amount of gathering seeds, weight per 1000 seeds and germination rate, respectively. As a results; correlation coefficient of number of capsules and amount of gathering seeds was pros(live correlation (r =0.9771**) , Weight per 1000 seeds (0.16g) was good from 39$\pm$2 capsules and amount of gathering seeds was 4.8g. So it is considered that method of gathering seeds wise proved to be a desirable 39: 2 capsules and amount of gathering seeds was 4- 5 gram.

  • We collected and examined germplasm resources of lettuces, edible chrysanthemums and mallows for organic farmers. We found that 3 genotypes (OL-51, OL-52, and OL-63) are suitable for organic cultivation. The main use of treatment for grey mold among eco-friendly pest control methods is helpful to increase efficiency of seed-gathering after collecting and evaluating a total of 64 kinds of lettuces-collected 43 South Korea local varieties, 8 kinds cultivated by the Highland Agriculture Research Center, 4 kinds of cultivated lettuces, and 9 kinds for sales- to choose appropriate kinds of lettuces for organic cultivation in South Korea. We chose those with more than 300 leaves (OC-18, OC-44, and OC-51) after evaluation of yield characteristics of a total of 62 edible chrysanthemums. We covered each genotype of seed of edible chrysanthemums when gathering the seeds by ourselves so as not to decrease the purity of each genotype. We chosed OM-38, OM-39, and OM-40 for their yield performance and germination rates among the total 41 genotypes of mallows. We selected 9 genotypes of lettuces, editable chrysanthemums and mallows with possibility of organic cultivation and found that they can be used permanently through self seed-gathering on organic farms.

  • 본 연구는 1991년부터 1992년까지 2개년간 경상북도 농촌진흥원 특용작물 시험포장에서 풍기종과 의성종을 공시하여 채종시기와 종자 후숙방법별 100립중과 출현율을 경시적으로 조사한 바 그 결과를 요약하면 다음과 같다. 1. 풍기종은 의성종에 비해 100립중이 무거운 대립 종이었는데 두 품종 모두 7월 25일경 100립중이 최대가 되었고 이후 점차 감소되어 7월 25일 이후 종자가 등숙되는 시기로 판단되었다. 2. 채종시기에 따른 출현율은 풍기종이 7월 5일 채종한 종자에서 7.8%의 출현율을 나타내었고 의성종은 10일정도 늦었는데 두 품종 모두 8월 15일 채종에서 평균 출현율은 풍기종이 96.7%, 의성종은 94.0%로 가장 높았다. 3. 종실채종과 협실채종에서 후숙시킨 것은 후숙시키지 않고 즉시 파종한 것 보다 출현율이 높았는데 특히, 7월 5일${\sim}$8월 5일 사이의 조기 채종에서 출현율이 높고 8월(月) 15일(日) 이후 채종에서 일정한 경향은 없었다. 또한 종실 및 협실 후숙에 있어서 7월 5일과7월 15일 채종한 것은 10일간 후숙한 것보다 $20{\sim}30$일 후숙시킨 것이 출현율이 약간 높은 경향이고 7월 25일 이후 채종에서는 차이를 볼 수 없었다.

  • The main objectives of this comparative study were 1) to compare the floristic similarity of species composition between the extant vegetation and seedlings from soil seed bank and 2) to quantify the potential contribution of soil seed bank to revegetation of forest in a constructed area, which is called "ecological impact mitigation" in conjunction with the power plant extension. Forest topsoil of seven plots was collected from the surface soil after measurements were taken on the ground vegetation in each plot. A greenhouse experiment was conducted and monitored to analyze the germination potential of soil seed bank. The forest topsoil was spread on plastic trays ($0.7m^2{\times}7$) filled with a 5cm layer of sterilized potting mix. The results of monitoring for 2 years in a greenhouse were as follows : 1) seedlings of soil seed bank per 4.9$m^2$ were 1,269 with 36 species (1st year) and 2,615 with 25 species (2nd year). 2) 38${\pm}$8% of the flora species were germinated from soil seed bank. It can be concluded that the use of soil seed bank would be effective to promote establishment of diverse species and vegetation. However, it behooves to continue monitoring on succession of vegetation and pursue revegetation with other methods for ecological restoration. Finally, adequate topsoil deposit and gathering methods should be studied properly.

  • This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by fertilizing of Sta-Green in pots. The results obtained are summarized as follows. Germination rate of Angelica acutiloba seeds collected in 2003 was $13\%$, while germination rate of seeds Collected in 2004 was above $91\%$. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than seed gathering in 2003. Especially, plant growth and yield of Angelica acutiloba grown in pot(The pots was filled with soil mixtures of Sta-Green and Peat Moss mixed with 45:55 ratio.) was the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by fertilizing of Sta-Green in pots and optimizing seed collecting time in greenhouse.

  • Many formats are used for recording and processing in the research of earthquake seismology and earthquake engineering. It is very difficult to program the Reading and writing algorithm for data processing because fill formats are very different from each other. It is suggested new file format of Korea Standard earthquake data (KSED) two types of ASCII and binary that are read and written easily. The Program package of basic data processing (Analyst) which has function of basic filtering spectrum analysis event gathering phase picking and location is developed In addition this program supports file transformation from another format(Mini SEED OMD K2) to KSED format.

  • 시들음병에 저항성인 수출 및 국내용 양배추 품종을 개발하기 위해 시들음병 저항성 계통인 $A337MSBC_5$를 모계로, 중국에서 수집하여 결구긴도와 구의 색이 우수하여 선발 고정된 397-$G_6$를 부본으로 선발하여 2008년부터 조합검정과 채종시험 및 지역적응성 시험을 거쳐 'CT-171' 품종을 육성하였다. 시들음병 저항성 검정은 뿌리 침지법을 이용하여 저항성 정도를 검정하였고, 그 결과 'CT-171' 품종이 대조품종인 '아시아볼', '중감 11호'에 비해 더 강한 저항성을 보였다. 'CT-171' 품종은 숙기가 58일로 대조품종에 비해 숙기가 빨랐으며, 내한성이 강하여 가을작형에 적합하였고 안토시안발현이 없는 특성을 가지고 있었다. 구중은 1.5kg, 구고 14cm, 구폭 15cm, 고갱이가 5.7cm로 재배환경에 고갱이 길이가 크게 영양을 받지 않는 안정된 특성을 가지고 있었다. 'CT-171' 품종은 2013년 2월 국립종자원에품종보호권이 최종등록 되었으며, 원예적 형질이 우수한 시들음병 저항성 품종으로 해외 수출용 및 국내 수입대체용으로 적합할 것으로 판단된다.
