정장용 효모로 알려져 있는 Saccharomyces cerevisiae Hansen CBS5926의 생균제 제조를 목적으로 생균수 증대를 위한 배양조건과 배양 후 얻은 균체의 효과적인 동결건조 보존법에 관하여 조사하였다. 포도당을 탄소원으로 하는 회분식과 유가식 배양에 비해 에탄올을 탄소원으로 하는 유가식 배양이 장점이 많은 것으로 나타났으며, 배양 72시간 후 2.2${\times}$10^9 cfu/ml의 생균수와 38g/l의 건조 균체량을 얻을 수 있었다. 에탄올을 탄소원으로 하는 유가식 배양으로부터 얻은 균체의 동결보존을 위한 보호제의 효능을 비교한 결과, 20% 백당(w/v)과 30% 유당(w/v)에서의 생존율이 16.3%로서 비교된 다른 종류의 동결보호제보다 효과적인 것으로 나타났다. 그러나, 백당, 유당 및 탈지분유의 혼합에 의한 동해방지 보호 효과를 비교한 결과 생존율이 12.4~16.5%로서 보호제의 혼합에 따른 생존율의 상승효과는 나타나지 않았다.

This study was conducted to obtain the basic data for using the Artemisia anuua as a new economic crop, thus Artemisia anuua was investigated their cultivation characteristics, yield, and variation of artemisinin contents by planting density and harvesting times. Seed characteristics of A. anuua have observed micro-size, and their germination optimum temperature was at 15 to 20 celsius degree. Planting density on the yield of A. anuua was increased high density better than low density. The highest yield was planted in the space of $30{\times}10$cm. Moreover, optimum harvesting time of A. anuua was investigated in early september and a periods of most highly detected artemisinin was time of before and after blooming of A. anuua.

This study is to eliminate the need for conventional high density plant factory's artificial light source such as LED to reduce the initial investment of the light source installation as well as the operation cost. Use of solar light could enhance the quality of the vegetables similar to those grown in the natural environment. Provision of solar light into the multilayer vegetable cultivation facilities and collecting maximum and sustainable sunlight without too much loss by tracing solar path and properly distributing it through careful control during daytime are crucial for realizing the investigated rooftop light shelf system for multi-layered vegetable cultivation. In this study, we developed an innovative way of effectively allocating sunlight inside even to otherwise shaded zone of a multi-layer vegetable cultivation facility. To prove the effectiveness of the system's sunlight collection and distribution capability, both simulation and experiment in Daejeon are performed and the outcome is analyzed.

Delayed stem senescence of soybean is a phenomenon of retarded leaf and stem yellowing, where plants maintain a high stem water content and remain chlorophyll in leaf and stem at maturity stage. This phenomenon was one of the most important physiological disease in Japanese soybean cultivation. The occurrence of delayed stem senescence was affected by sowing time. And the most of Japanese field, soybean seeds were sowed in June. June is the rainy season in Japan, and the soil water content of field become higher in this season. In this study, the effects of late sowing (July sowing) on the yield and the occurrence of delayed stem senescence in soybean cultivars Enrei, Tachinagaha and Ayakogane were examined from 2013 to 2015, in the experimental farm at Nihon University (Fujisawa-city, Kanagawa, Japan). The seeds of all cultivars were sowed in June (June-normal density plot) or July (July-normal density plot, July-high density plot and July-super high density plot) in field experiment. The pot experiments were carried out in 2014. In all cultivars, the yield of July-high density plot and July-super high density were higher than that of June normal density plot. And the yield of June-normal density plot was the same as that of July-normal density plot. In all cultivars, the occurrence of delayed stem senescence was increased by seeding in June sowing. And in July sowing plots, no significance difference in the occurrence of delayed stem senescence was observed among density plots. One of reason about the increasing the occurrence of delayed stem senescence in June-normal plot was the increasing of the damaged seeds by bean bugs. Add one of reason about the decreasing of the occurrence of delayed stem senescence of July plots was the decreasing of the amount of cytokinin supplied from root to top and water stress after the flowering time was improved compared with the June plot. In conclusion, the yield of Enrei, Tachinagaha and Ayakogane were not changed by changing the sowing time from June to July. In all cultivars, the occurrence of delayed stem senescence were decreasing by seeding in July.

시설재배 참외 주산지에서는 농가별로 가용 경지면적이 제한되어 있어 동일 포장을 이용한 장기간 연작이 불가피하므로 토양의 염류집적 문제와 함께 선충 피해가 매우 심각하다. 참외 휴경기에 하우스의 비닐을 제거하고 김장배추를 재배하는 이모작 체계는 다음 작기 참외 재배 시 토양 선충 밀도를 줄이는데 아무런 영향을 미치지 못하였다. 일반 참외 연작 하우스와 비교하여 참외-미나리 이모작 하우스에서는 다음 작기 참외 재배기간 동안 6월까지는 토양의 선충 밀도가 상대적으로 낮았는데, 이는 토양을 3개월 정도의 담수 상태로 유지함으로써 얻을 수 있는 효과로 판단된다. 참외-미나리 이모작 하우스에서 다음 작기 참외 정식 전에 살선충제를 처리한 경우에는 참외 재배 후반기까지 선충 밀도가 피해유발수준 이하로 유지되었다. 농가에서 휴경기에 배추와 미나리를 윤작물로 재배하는데, 이러한 단기윤작은 참외 연작 비닐하우스 토양의 선충을 효과적으로 방제하는 방법이 되지 못한다. 따라서 객토, 토양소독, 윤작물 재배 등의 친환경적인 선충방제 수단을 적극적으로 활용하고 그 효과를 극대화할 수 있는 방안들이 강구되어야 할 것이며, 필요에 따라서 적절한 살선충 약제를 사용함으로써 작물생산에 미치는 선충의 피해를 최소화시킬 수 있을 것으로 판단된다.

The study was conducted to analyze the growth characteristics comparison per planting density on the waxy corn early-planting culture for the paddy field in the southern province of south Korea. The cultivation period of early-planting culture for the paddy farming of the waxy corn are sown on February 15, 2016years, transplanting March 15 and harvest June 20. And it grew 126 days. The weather change according to the cultivation period of unheated plastic house early-planting culture, it was average temperature $14.6^{\circ}C$ and humidity 62.5%. And the temperature was 5.6 degrees Celsius warmer compared with the outside temperature and the humidity was 0.7 percent higher tendency. At the growth per planting density of waxy corn, culm length was average 224cm, the more it is high density culture the more was high trend. Stem diameter and ear length the more it is high density culture the more was lowed trend. The node number of $60{\times}20Cm$ was 12 nodes, fruit seting 5.7 nodes, tasseling number 94 days and silking number 96 days. In the ear characteristics per planting density, the size of ear length, seed setting length, ear width and ear weight the more planting density is high the more lowed that trend. The commodity percentage of planting density $60{\times}35Cm$ was the highest among other treatment as 69.1%. But, marketable yield was the highest planting density of $60{\times}20Cm$ as 4,543 ears/10a, and appeared in order $60{\times}25Cm$ 95%> $60{\times}30Cm$ 93%> $60{\times}35Cm$ 92%. The planting density on the waxy corn early-planting culture for the paddy farming in the southern province, the planting density analyzed to be effective planting of over 25% than normal season culture.
