$1912{\sim}2005$년 사이 우리나라의 평균 기온은 지속적으로 상승하여 약 $1.5^{\circ}C$ 상승하였다. 이는 지구 평균기온 상승($0.74^{\circ}C$)의 2배를 상회한 것이다. 장기적으로 농업기상정보시스템을 구축, 농업기상 예보 및 영농대책 자료를 농업인에게 제공해야 할 것이다.

This study was carried out to develop the proper cultivation methods of Brachythecium rivulare and Myuroclada maximowiczii which showed high-value for the interior landscaping and potting. Growth of two moss species cultivated in the compost covered with cloth was vigorous compared to that grown in containers only using cloth or compost, and their harvesting processes were easier. The growth and harvest easiness of mosses cultivated in compost were great rather than in bark or peatmoss. Compared to division, the spray of crushed mosses using mixer was effective for both gametophyte generation and their harvesting processes. In addition, the optimum inoculum for each container ($27{\times}17{\times}3cm$) was 2.0 g in B. rivulare and 4.0 g in M. maximowiczii. Overall growth of B. rivulare treated with nutrient solution (N:P:K=20:20:20) was inhibited compared to control, fresh-weight gain was reduced toward the higher concentration. But fresh-weight gain of M. maximowiczii was the highest with $0.25g{\cdot}L^{-1}$ treatment. Therefore, adequate moisture supply, after spraying crushed mosses (2.0 and 4.0 g each) in the compost covered with cloth, were the appropriate cultivation methods for B. rivulare and M. maximowiczii. Nutrient solution treatment with low concentration, during the cultivation period, would be the proper way only for M. maximowiczii.

Lodging of rice plant is the most important damage by unfavourable weather conditions in rice cultivation. High levels of nitrogen application and growing of Japonica rice variety is one factor to increase the lodging damage. Lodging of rice plant decreasing grain yield; 34% at milky. 21% at dough. 20% at yellow stage. decreasing grain Quality. increasing green rice. and increasing labor cost to harvest. To decrease lodging damage. the lodging resistant varieties will be selected and cultural practices such as amount and time of nitrogen application. planting density. water management. and disease and pest control methods have to be study for the short and strong culm. and good rooting system. Also. application methods such amount and time of plant growth regulators and new types of chemicals will be develop for the reducing lodging of rice plant. To decrease the lodging damage in direct seeding cultivation. first identifying the differences of lodging mechanisms between hand transplanting and direct seeding, second establish the suitable direct seeding methods such as seedling establishement. fertilization. and water menagement.

This experiment was conducted to understand the effects of climatic environment on the useful components in Angelicae gigantis radix. The variation of decursin contents in different seven cultivated regions and the relationship between decursin contents and meteorological factors were investigated. The appropriate analytical methods for decursin and decursinol angelate of Angelicae gigantis radix were HPLC method used normal phase column($\mu$-Porasil) and GC method. In different cultivated regions, the variation of decursin contents of Angelicae gigantis radix was relatively great, which were high with 4.86%, 4.75% in Bongwha, Yongcheon respectively and was low with 2.33% in Suwon. There was no significant relationship between decursin contents of Angelicae radix and meteorological factors during growing periods, but was negative correlation in average temperature and precipitation, and positive correlation in diurnal change of temperature, radiation and sunshine hours.

Production of Panax ginseng in Korea has been increased tremendously in the last two decades, the acreage and number of growers hating been spread across the country. Improvement of variety, on the other hand, has been seldom carried out during this period, rendering the ginseng growing risky and hazardous. Breeding work with such perennial crop as ginseng if rather time-consuming, and there are few genesources to start with. Authorities concerned with ginseng Production pay hwy little attention to breeding researches for nimbus of reasons. As this crop is cultivated over the entire area of Korea. Breeding work cannot be allowed to delay forth. In the precut article, improvement of ginseng was discussed from the view point of two different categories of brooding concept: (1) conventional breeding and (2) breeding based on the somatic tell genetics.

관행재배 농산물에 대한 유기재배 농산물의 생리활성성분 및 기능성 측면에서의 우수성에 대한 관심이 국제적으로 화두가 되고 있으나 일관성 있는 데이터가 제시되지 못해 논란이 이어지고 있다. 그래서 본 연구에서는 한국인이 일상적으로 섭취하고 있는 고추(녹광)를 대상으로 생산이력이 분명한 관행 및 유기 재배 시료를 이용해 주의 깊게 확립된 분석법을 이용해 유기 및 관행재배 고추의 생리활성성분 함량비교 및 기능성 평가를 행하였다. 그 결과 ascorbic acid, capsaicin, dihydrocapsaicin 및 총 페놀성 화합물의 함량은 녹색 및 적색 고추 모두에 있어 관행보다 유기재배 고추가 유의(p<0.05)하게 더 높은 값을 보였다. 그리고 flavonoid류(apigenin, luteolin, quercetin)의 함량은 녹색과 적색고추 모두 유의차는 인정되지 않았으나 관행보다 유기재배 고추에서 더 높은 경향을 나타냈다. 또 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid ammonium salt) (ABTS+) radical-scavenging 활성은 녹색고추에 있어서는 유기재배 고추가 관행재배 고추보다 더 높은 경향을 보였으며, 적색고추에 있어서는 유의(p<0.05)하게 높은 활성을 보였다. 고추추출물을 경구투여한 쥐 (Sprague-Dawley, 6주령, men, 180~250 g) 혈장의 동이온 유도산화에 대한 cholesteryl ester hydroperoxide (CE-OOH) 생성 억제능을 평가한 결과, 고추추출물을 경구투여한 쥐가 대조구보다 더 높은 CE-OOH 생성 억제능과 lag time연장 효과가 있음을 알 수 있었으며, 그 효과는 관행재배 고추보다 유기재배 고추에 있어서 더 우수한 것으로 관찰되었고, 녹색고추보다 적색고추에 있어 그 효과가 더 뛰어난 것으로 평가되었다. 이러한 결과는 위에서 분석한 각 시료에 함유된 항산화 성분들의 함량과 관련이 있는 결과라 판단되며, 유기재배 고추가 관행재배 고추보다 유용성분 및 생리활성 측면에서 더 우수함을 시사하는 결과라 사료된다. 그러나 한편으로 본 연구결과는 고추에 국한된 성과라 할 수 있으며, 유기재배 방법 및 다양한 환경조건에 따라 그 결과 또한 다양성을 보일 수 있음에 주의를 기울일 필요가 있다고 판단된다.

우리나라의 '91년도 시설채소 재배면적은 48,855ha로서, 그 중 과채류 재배면적이 27,570ha이고, 기존의 파이프하우스를 이용한 비가림 시설재배 면적은 3,970ha로서 매년 증가하는 추세이다. 극민소득의 증가와 식생활의 고급화로 인해 고품질 과채류의 소비가 급증하고 있으며, 한편 세계 농산물시장의 교역자유화 추세로 인해 채소류의 품질고급화와 생산비 절감을 통한 국제경쟁력제고가 절실히 요청되고 있는 실정이다. (중략)
