In order to determine and to reduce the differences between biochemical test method for the seed viability with T.T.C. (2, 3, 5. Triphenyl tetrazolium Chloride) reagent and germinator method, the topographical diagram of red colored formazan was carried out in 15-16 parts differences. From this resulted information, the classification of the typical staining reaction given for 3 species were derived into 3-4 parts for the germinable in normal seedling, the same as the following results. 1. Corn (Gram inaceae) * Entier embryo stained in bright red color. * Both extremities of scutellum unstained * Both extremities of scuttlium, coleorhiza and non-critial portions of radicle unstained. 2. Soybean (Leguminosae) *Seed completely stained in red color. *Minor unstained areas on cotyledons. *Extreme tip of radicle unstained; minor unstained areas on cotyledons 3. Radish (Cruciferae) *Seed completely stained. *Minor unstained areas on cotyledons. *Outer cotyledon mostly unstained: inner cotyledon completely stained Extreme tip of radicle unstained: large portion of outer cotyledon unstained.

본 실험은 답압에 의한 스트레스를 경감시킬 목적으로 폐타이어 칩을 한국잔디 식재 토양내 혼합 및 표면 배토시 그 효과를 평가하고자 실시하였다. 일반적으로 잔디는 답압이 진행됨에 따라 잔디 마모와 토양 물리성이 나빠져서 생육은 감소하지만 폐타이어 칩을 토양내에 처리함으로써 토양경도, 표면 경도 등 토양 물리성을 향상시키므로 생육을 향상시킬 수 있었으며, 토양 혼합처리는 가는 입자 20% 처리구에서 좋은 토양 물리성을 보였다. 배토처리시에는 무처리구와 비교시 표면의 높은 온도와 더불어, 피복효과와 마모를 가장 많이 받는 줄기 밑부분을 보호해 줌으로써 잔디 생육을 향상시킬 수 있었으며, 굵은 입자 10cm 처리구에서 표면온도가 높았다. 무기질인 폐타이어 칩을 소량으로 토양 혼합 및 배토처리함으로써 장기적인 효과가 예상되므로 향후 잔디면 조성 및 관리시에 이용할 만한 가능성이 있다고 생각된다.

본 연구의 목적은 퇴비단여과법(SCB)을 통해 생성된 액비의 골프장 잔디에 적용가능성과 자연순환농업정책의 새로운 수요처로서 적합성여부를 평가하기 위해 SCB 저농도액비가 크리핑벤트그래스의 생육과 토양특성변화에 미치는 영향을 조사하고자 2008년 4월부터 10월까지 6개월간 수행하였다. 시험전후 토양화학성의 변화는 SCB 저농도액비 처리구(S-1, S-2)와 대조구(CF)에서 무처리(NF)보다 토양 중 함유된 양분이 증가하였으나 토양화학성의 변화는 나타나지 않았다. 엽색지수와 엽록소지수 측정결과, CF보다 SCB 저농도액비 처리구(S-1, S-2)에서 높게 나타났으며, 잔디 생육량은 S-1과 S-2가 CF보다 각각 15%와 26%정도 증가하여 화학비료와 SCB 저농도액비를 혼합하여 처리하는 것이 잔디 품질과 생육을 향상시켰다. 시험 종료 후 잔디 조직 중 함유된 양분은 대조구와 SCB 저농도액비 처리구에서 큰 차이는 나타나지 않았으나 시험기간 중 조사된 잔디의 양분 흡수량은 SCB 저농도액비 처리구(S-1, S-2)에서 질소가 21~37%, 인이 28~57%, 칼리가 16~27% 증가되었다.

Effect of an antagonistic bacterium AF-2001, Pseudomonas cepacia, on control of turfgrass diseases as brown patch, Pythium blight, dollar spot, and large patch were evaluated in vitro and in vivo. Results obtained in this study are summarized as follows. 1. Pseudomonas cepacia AF-2001 showed antagonism against to the pathogens causing brown patch, Pythium blighe, dollar spot and large patch. Especially, the biological agent showed strong antagonistic effect on the causal pathogens of brown patch, dollar spot, and anthracnose, but weak on Pythium blight 2. Populotion density of P. cepacia AR-2001 decreased ra;idly in turfgrass soils. Initial population of the agent was 2.4$\times$107 cfu/g soil, however, decreased to 1.4$\times$103, 6$\times$102 and 0 cfu/g soil on 10, 20, and 30 days after application, respectively. 3. Under the controlled controlled conditions of $27^{\circ}C$ and 95% RH, P. cepacia AR-2001 showed 100% control efficacy on brown patch either by pre-treatment or post-treatment of infection. However, Pythium blight was controlled about 94% by pre-treatment and only 29% by post-treatment 4. In field trials, P. cepacia AF-2001 did not suppress large patch and the control efficacy on other turfgrass diseases was lower than agro-chemicals such as tebuconazole and metalaxyl. Control efficacy of brown patch, Pythium and dollar spot by the biological agent was 57.4%, 40.4%, 61.5~87%, respectively. 5. Growth, color and texture of creeping bentgrass were not differ significantly between AF-2001 treatment and untreated control.

This study was carried out to investigate the effects of pyroligneous acid on turfgrass growth and to propose usage for sustainable management on Korean golf course green. Each plot was treated with 0, 300, 500, and 800 acid to water solution. On all the plots, turfgrass growth increment and visual quality were measured at fried times. The data were subjected to paired samples t-test and corelation analysis. The summarized results are as follows; 1) Leaf growth increment, density, and root spread depth of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Particularly, 1: 500 diluted solution was superior to the others. 2) Color, texture, and uniformity of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Especially, 1: 500 diluted solution tended to be superior to the others. 3) There were no symptoms of disease in all plots treated with the diluted pyroligneous acid. 1 500 and 1: 800 diluted pyroligneous acid were not thought to trigger or promote disease. 4) Before and after investigating the effect of pyroligneous acid on turfgrass growth ,the soils were analyzed. In all treatments, the chemical properties of the soils did not change noticeably. The chemical properties of the soils might be not changed by the diluted pyroligneous acid treatments. 5) Considering the results mentioned above, 1: 500 diluted pyroligneous acid was the most effective. Though pyroligneous acid is an organic fertilizer and contains only a little nitrogen and phosphorus, 1: 500 diluted pyroligneous acid promoted turfgrass growth effectively. Thus this use might lead to a reduction in the amount of fertilizers used and result in ecologically responsive management of Korean golf courses.

Five soil mixture with seven turfgrass species when placed over a plastic sheet were evaluated for influence on covering rate, visual rating, visual color and sad development. The result were as follows. 1. The last covering rate was high on sand+bark and on Kentucky bluegrass, respectively while the early covering rate was high on sand+peat and on perennial ryegrass and tall fescue. respectively. 2. Both sand and sand+sandy loam caused poor effects on the covering rate and the visual rating. 3. The early growth was good on perennial ryegrass but the covering rate and the visual rating gradually turned poor because of summer drought. 4. Visual color was high on sand+bark and on Kentucky bluegrass, respectively. 5. Covering rate, visual rating and visual color was best evaluated on Kentucky bluegrass during winter. 6. Sad was highly developed on sand+bark and sand+peat as compared with on the other soil mixture. 7. The carpet-type sad was best developed on Kentucky bluegrass.

This study was carried out to determine the possible use of volcano eruption sand at Merapi mountain area compared with clayey soil, alfisol as turfgrass growing media. Indonesia has abundant source of eruption sand and clayey soil. Native zoysiagrass (Z. matrella) was collected from Sleman district and seashore paspalum (P. vaginatum) from Solo region. The experimental plots were treated with both organic and inorganic fertilizers. Zoysiagrass and seashore paspalum can grow on the mixture of eruption volcano sand and alfisol soil. Fertilizers application increased turf color, surface coverage rate and recovery rate of turfgrass. While fertilizer treated alfisol have no effect on the length and dry weight of zoysiagrass root. Mixing of volcano eruption sand on growing media resulted in longer root length, higher shoot dry weight of zoysiagrass than in alfisol soil. Type of fertilizer affected the pH, soil organic matter, total N, available P, available K and electrical conductivity of sand and alfisol after cultivation. Similarly to zoysiagrass, the recovery of seashore paspalum was increased by application of fertilizer, even the inorganic fertilizer showed faster recovery than organic fertilizer. Surface coverage of seashore paspalum was faster than that of zoysiagrass with or without fertilizer.
