함평만 조간대 염생식물조사를 위하여 염생식물군락이 형성된 6개지역을 선정하여 식생분포 및 현존량을 조사하였다. 우점군락은 퉁퉁마디군락(Salicoenia herbacea community), 칠면초군락(Suaeda japonic community), 나문재군락(Suaeda asparagoides community), 좀보리사초군락(Carex pumilalini community), 가는갯능쟁이군락(Atriplex gmelini community), 갯개미취군락(Aster tripolium community), 갯잔디군락(Zoysia sinica community), 해홍나물군락(Suaeda maritima community), 갯질경군락(Limonium tetragonun community), 갈대군락(Phragmites communis community), 실망초군락(Erigeron bonariensis community)으로 구분되었다. 염생식물 군락의 생산량은 1,680∼2,170 g.d.w./㎡으로 갈대군락이 가장 높았고, 갯잔디 군락이 310∼500 g.d.w./㎡으로 가장 낮았다. The coastal vegetation was classified by the Braun-Blanquet's method and the biomass was investigated at the wetland of Hampyung-Man. The vegetation of the study area was classified with 11 coastal communities as follows: Salicornia herbacea community, Suaeda japonica community, Suaeda asparagoides community, Carex pumilalini community, Atriplex gmelini community, Aster tripolium community, Zoysia sinica community, Suaeda maritima community, Limonium tetragonun community, Phragmites communis community, Erigeron bonariensis community, Biomass was highest in Phragmites communis community (1,680∼2,170 g.d.w./㎡) and lowest in Zoysia sinica community (310∼500 g.d.w./㎡).

토마토 저온기 시설재배 시 과실착과 및 비대를 위하여 GA-TB를 10,000배액, tomatoton 100배액을 처리 시기별로 달리하여 처리한 결과를 요약하면 다음과 같다. 1. 과중은 착과제인 GA-TB 및 tomatoton를 처리한 것이 무처리에 비해 다소 높은 것으로 나타났으며, GA-TB 처리구의 제 1화방 과중은 281.1g 으로 무처리구의 214.4g보다 66.7g 많아 GA-TB가 다른 착 과제와 같이 과실 비대에 효과가 있는 것으로 나타났다. 2. GA-TB 처리에 따른 과실의 과장, 과폭도 무처리구에 비해 유의적인 차이는 없었으나 착과제의 처리시기에 따라서는 다소 차이가 있었다. 3. 과형지수는 1.4 정도로 처리구 모두 slightly flattened형태로 나타나 GA-TB처리가 토마토 외형에는 영향을 주지 않았다. 4. 과실의 품질에서는 GA-TB 처리구, tomatoton 처리가 과실착색 및 과실경도에는 영향을 주지 않았으나 산도, 당 함량은 GA-TB 처리구가 무처리구에 비해 다소 높았다. 5. 저장성은 GA-TB 및 tomatoton 처리에서 초기 부패율이 다소 낮은 반면 후기 부패율은 무처리구가 높게 나타났으며 GA-TB 농도는 기준량의 2배까지 약해가 없었다. In order to improve fruit set and fruit enlargement of tomato, GA-TB 10,000 times and tomatoton 100 times were treated with different time on Tomato culturing during low temperature in a plastic house. The results are followings. 1. Fruit weight of GA-TB treated tomato was 281.1g which was 66.7g higher than 214.4g of non-treated, indicating that GA-TB has effect improving fruit enlargement in tomato. 2. GA-TB did not showed significant difference in the length and width of fruit compared with non-treated, but showed slightly difference according to treatment date. 3. Fruit shape index was about 1.4 and fruit shape was slightly flattened in all tomatoes treated in this study. 4. GA-TB and tomatoton showed no difference in fruit color and fruit firmness compared with non-treated . GA-TB promoted the acidity and sugar contents of tomato compared with non-treated. 5. Decay rate in GA-TB and tomatoton was slightly lower than non-treated during storage. No injury was observed at even 2 times of standard concentrations in GA-TB

In order to obtain the basic information for clarifying the mechanism of water stress, effects of water removal (15 days after emergence) on dry weight, chlorophyll and reducing sugar content, α-amylase activity and isozyme pattern were investigated in the early growth stage of soybean plant. The results are as follows. 1. Dry weight of shoot was increased in both the control and the treatment, but the degree of increase was remarkably lower in the treatment than that in the control. After 9 days of the treatment, it was decreased about 42% compared to the control. 2. Water content(%) and chlorophyll content in the leaves showed nearly unchanged in the control, but remarkable decrease in the treatment. After 9 days of the treatment, they came to 60% and to 4.5mg.g DW and decreased 26% and 42%, respectively, compared to the control. 3. Reducing sugar content and α-amylase activity in the leaves remained at almost constant level in the control, but showed almost linear increase in the treatment. After 9 days of the treatment, they came to 26mg/g DW and to 20 units, and reached about 2 and 1.6 times, respectively, compared to the control. 4. α-amylase isozymes showed only b (light stained) and c (dark stained) isozymes in the control and remained in color intensity during the period of investigation, while, in the treatment, a new a band was observed 3 days after the treatment, and a and b isozmes also became dark stained condition from 7 days after the treatment.

In order to find out the influence of shading degree on the growth, pod setting, protein contents, RuBPCase activity, photosynthesis and yield in soybean plants, two soybean varieties, Hill and Etaka were cultivated under the 0%(full sun light), 20%, 65% and 90% shading conditions. Protein contents, RuBPCase activity and photosynthesis of leaves in Hill were decreased linearly with the higher shading, but those in Etaka were increased up to 20% shading, and then decreased more rapidly than Hill when the shading was above 65%. Pod sets were decreased with the higher shading degree, and those of the degree were severe in upper nodes. The stem heights were increased in accordance with the shading up to 65%, but stem diameter and No. of branches were decreased linearly with the higher shading degree. The yield of Hill was decreased linearly with the higher shading degree, but that of Etaka were increased up to 20% shading, and decreased inure severely than Hill when the shading was above 65%. From the above results : Etaka is more suitable than Hill to weak shading which occurred in the case of intercropping, companion cropping and alternating cropping, and the shading degree must not go over above 20%.

전남 해남군 화원면에 금호방조제 건설 후의 염습지의 습지 환경 및 식생의 분포에 관한 지도 데이터 베이스를 구축하기 위하여 토양의 유기물함량, 총 질소량, 나트륨함량 지도 및 습지의 잠재자연식생도(wetland potential natural vegetation map)를 작성하였다. 토양의 유기물함량과 나트륨함량은 담수가 유입되는 내륙쪽에 인접한 간척지역은 가장 낮은 값을 보였으며, 반대로 해안쪽이 간척지역이 가장 높은 값을 나타내었다. 토양의 sand함량과 총질소함량은 금호방조제 밖의 화원면 마산리에서 가장 낮았고, 내륙쪽에 인접한 간척지역은 가장 높은 값을 보였다. 금호호 주변 간척지의 잠재식생분포는 염분농도가 낮고 지하수위를 통하여 담수가 공급되는 육지쪽에는 갈대군락이, 해안선에는 호수주변으로 갈수록 차례로 나문재군락, 퉁퉁마디군락 및 칠면초군락이 분포할 것으로 추정되었다. To establish the map database on wetland soil environment and vegetation distribution after constructions of the Kumho seawalls in southwestern coastal wetlands in Korea, the maps of soil organic matter, total nitrogen and sodium content and wetland potential natural vegetation were made. Soil organic matter and sodium content were lower in reclaimed area near the land than near the sea. Soil sand and total nitrogen content were lower in the outside of the Kumho Seawalls than in reclaimed area near the land. In the distribution of wetland potential natural vegetation after constructions of the Kumho Seawalls, Phragmites communis community will be distributed in reclaimed area near the land, in which fresh water is streamed and then Suaeda asparagoides, Salicornia herbacea and Suaeda japonica community will be distributed from the land to the sea.
