This research was conducted to determine the effect of the pre-treatment of mulberry charcoal on the salt tolerance response in Kentucky bluegrass ‘Perfection’. As this results, 400 mM NaCl treatment reduced turf growth such a fresh and dry weight, and induced physiological damages like decreased chlorophyll content and increased electrolyte leakage. The pre-treatment of mulberry charcoal, however, mitigated those growth and physiological responses associated with NaCl stress, regardless of the concentrations of charcoal solution. Furthermore, it was observed that higher K ion concentration by mulberry charcoal pre-treatment reduced Na ion in shoot. This research suggests to be a possibility of planting turf grasses in reclaimed land or higher salt accumulated area using a mulberry charcoal treatment. 본 시험은 뽕나무 숯이 염해의 내성에 미치는 영향에대해 알아보고자 한지형 잔디인 Kentucky bluegrass를 공시하여 수행하였다. 잔디의 생체중과 건물중 등의 생육은NaCl 400 mM의 처리에 의해 크게 억제되었으며 NaCl처리에 의해 엽록소 농도의 저하와 전해질의 누출상승 등생리적 장해를 초래하였다. 이러한 생육의 억제와 생리적장해는 뽕나무 숯의 전처리에 의해 크게 경감될 수 있었다. 뽕나무 숯의 전처리는 K이온의 흡수를 도와 Na이온을 체외로 배출시키는 것을 확인하였다. 본 시험의 결과뽕나무 숯의 처리는 염해에 약한 잔디류의 간척지 및 염류가 높은 토양에서 식생조성이 가능 할 것으로 사료되었다.

배은지,이광수,허무룡,임채신 한국원예학회 2012 Horticulture, Environment, and Biotechnology Vol.53 No.6

The study was conducted to clarify the effects of silicon on the salt-sensitive ‘Perfection’ and ‘Midnight’Kentucky bluegrass (Poa pratensis L.). The 400 mM NaCl treatment reduced shoot length, fresh and dry weight of shoot and root as well as relative water content and chlorophyll and carotenoid content in both cultivars. The NaCl caused an increase in electrolyte leakage, malondialdehyde concentration and H2O2 in both cultivars. This physiological interferences and visually noticeable disturbances in Kentucky bluegrass were significantly alleviated by the addition of silicon after salt stress. In ‘Perfection’, for example, 0.1 mM silicon application after NaCl treatment significantly increased in the shoot length by 48%, the fresh weight of the shoot by 72%, the relative water content by 61%, and the total chlorophyll content by 57%. Compared to the NaCl-only treatment, significant reduction in the electrolyte leakage and the concentration of malondialdehyde and H2O2 were observed in silicon treatment.

배은지,전창욱,홍아름,이광수,곽연식,Bae, Eun-Ji,Cheon, Chang Wook,Hong, A-Reum,Lee, Kwang-Soo,Kwak, Youn-Sig 한국잡초학회한국잔디학회 2017 Weed & Turfgrass Science Vol.6 No.3

들잔디 재배지역에 갈색퍼짐병을 방제하기 위하여 Tebuconazole 약제 및 Streptomyces sp.와 Burkholderia sp. 미생물을 처리하였다. 무처리구에 비해 Tebuconazole 약제 처리구, Streptomyces sp., Burkholderia sp.와 Streptomyces S8 미생물 처리구는 잔디의 생육, 엽록소와 카로티노이드, 프롤린 함량은 유의하게 증가하였며, MDA 함량은 감소하였다. 토양미생물인 Streptomyces sp., Burkholderia sp.와 Streptomyces sp. S8 처리에 따라 갈색퍼짐병 병원균밀도 감소로 갈색퍼짐병의 증상이 완화되어 정상적인 잔디로 생육이 된 것으로 판단되었다. 이러한 결과는 사용된 미생물이 잔디의 생물적 방제와 잔디의 생육 촉진 미생물로 이용될 수 있음을 시사한다. To prevent large patch disease, caused by Rhizoctonia solani AG-2-2, in zoysiagrass a fungicide, Tebuconazole and three microbial agents Streptomyces sp. Burkholderia sp. and Streptomyces sp. S8 were applied in commercial turfgrass cultivation field in Sanchung, Gyeongnam, Korea. All treatments showed 50% reduced the pathogen population in thatch layer throughout the yearly cultivation period. Not only reduced the pathogen population, Tebuconazole, Streptomyces sp. Burkholderia sp. and Streptomyces sp. S8 treatment also enhanced turfgrass growth, chlorophyll and proline content. Malondialdehyde contents in each treatment was reduced from 6.2~28.9% when compared with the control. Taken together, reduction of pathogen population in soil lowered the disease incidence or severity, and allowed the turfgrass developed as normal condition. The results suggested that the selected microbial agents may use as biological control and growth promotion agents for the Zoysia turfgrass.

Seeded variety of zoysiagrass has not been bred yet in Korea. Development of seeded zoysiagrass cultivar will be very important for the growth of turfgrass industry internationally as well as domestically. This research was conducted to investigate seed yield and germinability of 102 collected native zoysiagrass ecotypes in South Korea. Two hundred and seventy seven ecotypes were collected from various locations including coastal and mountain areas, while 102 morphologically distinct and seed producing ecotypes were selected and planted in 1 m × 1 m maintenance plots. Seed yield ranged from 0.1 to 32.2 g m−2. Highest yielding line was a medium leaf type zoysiagrass of Z6011 with 32.2 g m−2. Most collected lines showed seed germination rates of below 50%. However, Z2095 showed highest germination rate of 78%. Considering germination rate and seed yield, collected lines of Z6011, Z 6015, Z1075, ZN1008, and Z1084, which were mostly medium leaf type and Z. japonica types, showed reasonably high potential to be used as breeding lines for high yield seed varieties of zoysiagrass. 국내에 종자형 품종 개발은 아직 전무한 상태이다. 한국잔디의 종자형 품종 개발은 국내외 잔디산업 발전을 위해서도 매우 중요한 일이다. 한국잔디 자생지인 국내 동,서, 남해안과 내륙지방에서 277 생태형을 수집 하였고, 이중에서 종자를 맺는 102개 수집계통에 대한 종자 수확량과 발아율을 조사하고자 본 연구를 수행하였다. 종자 수확량은0.1~32.2 g m−2의 범위를 보였다. 수확량이 가장 많은 계통은 중엽형인 Z6011로 32.2 g m−2로 나타났다. 수집계통의발아율은 대부분이 50%이하로 낮게 조사되었다. 발아율이가장 높은 계통은 78%를 보인 Z2095로 조사되었다. 종자수확량이 높으면서, 발아율이 높은 계통으로는 Z6011, Z6015, Z1075, ZN1008, Z1084 등을 선발하였으며, 대부분 중엽형계통과 Z. japonica 계통이었다. 상기 선발 계통들은 향후다수확 종자형 품종육성을 위한 유용한 유전자원으로 활용될 수 있을 것으로 생각된다.

This study was performed to determine the effects of silicon on zoysiagrass after the application of drought stress. The daily amount of water or scilicon solution was 150 ml per a pot. For 14 days, plants were treated with 0.1 and 1.0 mM silicon (Si) and with distilled water for control and the drought only-treatment. Afterward, the plants in Si and drought treatment were exposed to a 21-day under drought stress condition but the plants in control received water. The results indicated that the growth and the moisture and chlorophyll contents decreased in the drought only-treatment and 0.1 mM Si compared to the control. However, 1.0 mM Si showed an increase in the growth with a significant increase of water and chlorophyll contents. The MDA and H2O2 concentrations and electrolyte leakage decreased, while the radical scavenging capacity increased in 1.0 mM Si. 1.0 mM Si showed little to no differences in the growth and no differences in water and chlorophyll contents, electrolyte leakage, MDA and H2O2 concentrations and antioxidant capacity compared to the control. These results suggested that application of silicon is useful for drought tolerance improvement of zoysiagrass under drought that is occurring in turf fields.

It is important for genetic resources to collect and identify in native medium-leaf type zoysiagrasses species distributed in Korea. This study was conducted to investigate morphological variation and characteristics of native medium-leaf type zoysiagrasses from coastal, island and inland regions in Korea. Among them, 75 collected lines was confirmed to have various morphological variations, accessions were classified into 2 main based group coastal and inland regions by morphological characteristics and site environment. Group I included Z. sinica type, this group showed 3.7 mm in leaf width, 29 in number of seed per spikelet and 5.0 mm in seed length. Group II included Z. japonica type, this group showed 4.4 mm in leaf width, 42 in number of seed per spikelet and 3.5 mm in seed length. There is a need for additional research on growth characteristics and the molecular level for the introgressive hybridization between species which confirmed that cross-pollination is possible due to protogyny. The individuals showing variations should be preserved as valuable genetic resources for the expansion of variations in zoysiagrasses, and the results of this investigation on the genetic resources collected will be highly valuable in breeding high quality turfgrass.

This study was conducted to identify the morphological characteristics and variations level by site environment of native bermudagrass (Cynodon spp.) from costal and island region in South Korea. Soil chemical properties and morphological characteristics were investigated. There were significant differences in plant height,leaf width, leaf length, cotton on leaf blade, stolon, and number of seed per spike depending on where they were collected from natural habitat. We have discovered a variety of variation among the investigated traits in Korean native bermudagrass ecotypes. There were broad leaf and fine leaf types of native bermudgarass in S. Korea. Adaptability was in very high on inadequate environment in bermudagrass with broad leaf types, it has also been suggested that management worth in terms of use. These results may provide basic information for bermudagrass breeding development and the collected types during this investigation would be worth being preserved as genetic resources for further breeding purposes. 본 연구는 국내 해안 및 도서지역에 자생하고 있는 버뮤다그래스를 지역별로 수집하여 입지환경에 따른 형태적변이 정도를 알아보고자 수행되었다. 이들 입지환경, 토양의 화학성과 형태적 특성을 조사하였다. 수집된 자생지에따라 초장, 엽폭, 엽장, 잎털, 포복경 및 화수당 종자수 등에서 큰 변이를 보여 조사 형질 간에 다양한 변이를 보이는 것을 확인할 수 있었다. 광엽과 세엽 특성의 버뮤다그래스가 존재하고 있었으며, 광엽형의 버뮤다그래스의 경우 열악한 환경에서의 적응성이 매우 높아 중·저관리의잔디면에 이용 가치가 높을 것으로 생각된다. 상기 입지환경과 형태적 특성 조사 결과 및 수집된 유전자원들은앞으로 유전자원으로서 보존 가치가 높으며, 유용유전자를 보존할 수 있는 체계가 마련되어야 할 것으로 판단된다.

배은지,이광수,박남창,허무룡 경상대학교 농업생명과학연구원 2012 농업생명과학연구 Vol.46 No.2

본 연구는 배토작업에 따른 한국잔디의 적정 밀도와 질을 유지하기 위한 배토의 효과를 알아보기 위해 수행되었다. 배토를 하지 않은 처리구와 배토높이 2, 4, 8과 16 ㎜ 처리구를 비교한 결과, 초장, 지상부, 포복경과 지하부의 생체중과 건물중, 포복경과 지상부의 개수는 배토높이가 높아질수록 증가하는 경향을 보였고, 엽록소와 카로티노이드 함량 또한 증가하였다. 지상부와 지하부의 전량질소, 전량인산, 전량가리, 전량고토, 전량석회도 배토를 하지 않은 처리구보다 배토높이가 높아질수록 증가하는 경향을 나타내었다. 배토를 하지 않은 처리구보다 배토처리구에서 산도가 증가하는 것으로 보아 알칼리화 되는 것으로 나타났고, 유기물 함량, 전질소, 치환성양이온(K+, Na+, Ca2+, Mg2+) 농도는 증가하는 경향을 보였으나 유효인산은 감소하였다. 배토처리를 하지 않은 처리구보다 배토처리구에서 잔디의 생육이 증가하고, 밀도율이 높았으며, 토양 화학성도 양호하게 변화하였다. 배토높이에 따른 효과는 8 ㎜에서 토양내 유기물 함량과 전질소가 가장 높았고, 생육이 향상되는 것으로 보아 한국잔디에 대한 적정 배토높이인 것으로 판단된다. This study was performed to determine the effect of topdressing on maintaining the quality and density of zoysiagrass. An increase in the topdressing height from 2 ㎜ to 16 ㎜ (2, 4, 8, and 16 ㎜) led to an increase in the plant heigh, fresh and dry weight of shoots, roots, and stolons. The number of shoots, stolons and concentrations of chlorophyll and carotenoid also increased with increasing topdressing height. Moreover, total concentrations of nitrogen, phosphoric acid, potassium, magnesium, and lime in shoots and roots were enhanced as topdressing height increased. Acidity and the concentrations of organic matters, total nitrogen, and exchangeable cations (K+, Na+, Ca2+, and Mg2+) of topdressed soil was higher than not topdressed soil, while the amount of available phosphoric acid in topdressed soil was lower than not topdressed. The topdressed soil enhanced the growth and density of zoysiagrass, while it was a crucial factor to affect the chemical property of the soil. Optimum topdressing height was thought to be 8 ㎜ since topdressing the soil with topdressing height of 8 ㎜ not only improved the growth of zoysiagrass but also resulted in the highest concentration of nitrogen and organic matters in the soil.
