For the study of ecophysiological characteristics of ground cover plant with shade tolerance, the material productivity and the growh characteristics were analyzed in Hosta clausa community at experimental farm of Kemyung College from March to October. The installation of experimental plots were split into control plot (full sunlight), 30%, 50%, 70%, shading rate by completely randomized design method. After the transplant, to take into account the edge effect of plant population, the plants were selected from each plot by random sampling every 10days. The following results were obtained; Then number of leaf, length of leaf and width of leaf length of leafstack remarkably showed high tendency under 30%, 50% shading plot as compared with control, 70% shading plot for the exmination as the process of develpment. They showed characteristics as herbaceous ground with shade tolerance under conparatively low the light condition and they ettain a stabilized development.

To obtain the basic informations necessary to develop the production technology of vegetable soybean seeds, this study was conducted at the National Crop Experiment Station, RDA, Suwon, Korea in 1993. Seeds of three vegetable soybean varieties, 'Mikawashima', 'Hwaeomputkong', and 'Seokryangputkong' produced at Pyeongchang, a highland in Korea and introduced from Japan were planted on April 20 in the field. The emergence rate among varieties was significanlty different. Emergence rate of seeds produced at Pyeongchang was higher by 7% than that of the seeds from Japan. Rate of pod infection by Phamapsis spp., brown spot by Septaria glycines, soybean mosaic virus(SMV), and downy mildew by Peronospora manshurica in the field was not different between locations. The growth characteristics, yield components, and green pod and grain yields were not different between locations. Therefore, it was proved that the production of vegetable soybean seeds with the better quality and higher emergence is possible in highland, Korea. possible in highland, Korea.

Highly positive correlations were obtained between the growth duration of the 1978 IReTN entries in Chuncheon, Korea and all the experimental sites in 7 other countries. Among the entries the photoperiod responsive varieties had very long growth duration in Chuncheon although relatively early in flowering in the other low latitude sites. Selection under Korean conditions would eliminate the short growth duration varieties caused by photoperiod sensitivity in tropics or sub tropics. Except for photoperiod sensitive rices, selection of varieties or lines for optimum growth duration before further evaluation in other low temperature areas would be most effective in Chuncheon, Korea.

벼의 생육과 수량에는 토양과 생물환경 못지 않게 기상환경도 중요하다. 기상환경 중에서도 기온과 일조시수의 영향은 매우 커서 이에 대한 연구가 많이 이루어 졌다. 따라서 본 시험에서는 여수지역에서의 10년간 기상조건과 벼의 수량성을 비교하였던바 생육 초기의 영양생장기에 비하여 생육후기의 생식 생장기에서의 높은 고온과 많은 일조시간(일사량)은 증수되는 경향이 었다.

This study was conducted to select an excellent goods and to estabilish the plant density of Amorphohpallus konjac. K about 3 local varieties and 2 introduced varieties through each fertilizer level. 1. Plant height and leaf width were increased according to increasing fertilizer level, and tuber yield was the highest at N-P$_2$ $O_{5}$ -K$_2$ O (14-10-14kg) per 10a as 390kg in Geumsan. 2. The more tuber size was large, the more yields per plant due to increasing the plant height and leaf width at low densities, while yields per 10a was decreased. 3. Among 5 varieties used, Jechon cultivar was good as a propagating variety because of increasing number of tuber and bulblet and Japan cultivar was high tuber yield per 10a.

This study was carried out to investigate the characteristics of root growth in Kentucky bluegrass sod(KBS) and creeping bentgrass sod(BGS) transplanted in summer(August 9) and fall(September 19), respectively. Hydroponic system was also used to observe rooting development in the study. Root development differed in KBS by transplanting time. It reached to more than 5 cm after 100 days In summer and 50 days in fall. However, BGS's root grew over 6cm after 40 days, regardless of the season. There was no significant differences in BGS, regardless of any cutting treatment. In the case of KBS, it was best with sod culled with 0.5cm deep and 1.5cm long. But it grew beyond 5 cm in root growth under any treatment after 40 days in transplanting. In a hydroponic study, BGS produced root over 100cm for 80 days through a summer season. However, the root of KBS did only grow in condition below $20^{\circ}C$. These results indicated that root growth characteristics were variable in BGS and KBS. It was considered that rooting development of BGS might be improved with sufficient irrigation in summer, and KBS grows well in lower temperature of $10{\sim}18^{\circ}C$, as compared with BGS. As to establishing the lawn with a sodding method, it should be careful in transplanting time, especially KBS.

This study was conducted to investigate the effect of Lactobacillus sp. and Saccharomyces sp. on turf quality, shoot and root growth of creeping betgrass in golf course by measuring turf color index, chlorophyll content, dry weight of shoot and root, T/R ratio and root length. Fertilizer treatment was designed as follows; nonfertilizer (NF), control (CF; compound fertilizer), microorganism medium(MO; CF+MO)), microorganism medium contained Fe(MO-Fe; CF+MO-Fe) and microorganisum medium contained S (MO-S; CF+MO-S). Soil properties investigated after experiment was scarcely affected by applied fertilizers in root zone of creeping bentgrass. The turf color index and chlorophyll index of MO, MO-Fe, MO-S treatment were higher than those of NF, and similar to those of CF. The turfgrass root in MO and MO-Fe treatment was longer than others. The dry weight of shoot in MO and MO-S was higher than CF and that of root in MO and MO-Fe, and dry weight of MO was increased than that of NF and CF, by 26% and 6%, respectively. AS compared with NF, T/R ratio of CF, MO, MO-Fe and MO-S was increased, and MO and MO-Fe was similar to CF, MO-S higher. Nutrient content in CF, MO, MO-Fe and MO-S was contained more than in NF, and it was higher in shoot. These was suggested that application of MO induced the development of quality and growth of creeping bentgrass by assisting root growth and nutrients uptake.

산채는 주로 산지에서 자생하는 것을 채취하거나 자생지와 비슷한 환경의 임간에서 재배하여 수확을 한다. 본 시험은 차광처리를 통해 산지가 아닌 노지에서 산채 재배 가능성을 검토하고자 하였다. 대상작목은 개미취(Aster tataricus), 눈개승마(Aruncus dioicus var. kamtschaticus), 단풍취(Ainsliaea acerifolia), 박쥐나물(Parasenecio auricudatus var. matsumurana), 산마늘(Allium microdictyon), 어수리(Heracleum moellendorffii), 우산나물(Syneilesis palmata)이다. 시험작목을 전북 남원시 허브시험장(표고 500m) 포장에서 2017년 4월에 종묘를 정식하여 약 2년간 재배하였다. 고온기인 5월부터 9월까지 35%, 55%, 75%, 95% 차광정도를 달리하여 설치 한 후 시설 내의 기온, 상대습도 등 환경조건 및 재배작물의 고사율, 출현율, 생육특성 등을 조사하였다. 시설 내부의 평균 기온은 차광정도가 높아질수록 다소 낮아졌으며, 상대습도는 점차 높아졌다. 차광정도별 고사율을 조사한 결과 개미취, 어수리, 우산나물의 경우는 차광비율에 상관없이 각각 3.6%, 5.7%, 9.8%로 낮게 나타났다. 반면 단풍취와 산마늘의 경우 차광 비율에 따른 편차가 크지는 않았지만 최대 고사율이 각각 20.0%, 36.8%로 다소 높게 나타났다. 또한 눈개승마 75% 차광에서 50.0%, 박쥐나물 35% 차광에서 100% 고사율을 보여 적정 차광비율 선정 필요하다고 판단된다. 정식 2년차 4월 평균 출현율은 개미취 100%, 눈개승마 86.2%, 단풍취 84.3%, 박쥐나물 77.9%, 산마늘 97.5%, 어수리 88.9%, 우산나물 96.3%이었다. 다만 단풍취, 박쥐나물은 차광정도가 높아질수록 출현율이 높아졌고, 어수리는 차광정도가 높아질수록 다소 출현율이 낮아졌다. 또한 생육특성 조사 결과 초장은 단풍취를 제외하고 차광처리별 경향성이 뚜렷하게 나타나지 않았으며, 엽장과 엽폭은 산마늘을 제외한 작목들은 차광이 강할수록 커지는 경향이었다. SPAD 값은 개미취와 산마늘은 처리구역별 차이가 없었으나, 나머지 작물은 차광이 높아질수록 SPAD 값도 커졌다. 시험결과 표고 500m지역에서 개미취, 산마늘, 어수리, 우산나물은 차광수준에 따른 생육의 차이가 크지 않거나 차광이 낮아도 생육이 비교적 양호하였다. 그러나 단풍취와 박쥐나물은 차광정도에 따라 생육의 차이가 분명하였으며, 차광이 높아질수록 생육이 좋아졌다. 이를 바탕으로 산채류 노지재배를 위해서는 연차 간 작목별 생육특성, 수량성, 상품율, 경제적 분석 등의 추가적인 조사가 이루어져 할 것으로 여겨진다.

Five of each lowland and upland rice varieties were planted in a seedling hox with three replications of randomized complete block design and it was desiccated up to complete water stress in certain leaf stage. The desiccated rice plants were supplied with water again to check survival ability of rice plant from wilting. All of the lowland varieties which showed lower yield in upland condition were superior to upland varieties in recovery ability from desiccation. Some of the morphological characteristics in relation to the recovery ability also were discussed.
