잔디 엽병을 유발하는 잠재인자로서의 남조류 (Blue-Green algae)에 대한 관찰 보고

박대섭,이형석,홍범석,최병만,전재찬 한국잔디학회 2008 Weed & Turfgrass Science Vol.22 No.2

Recently irregular dark-colored patches were found on the Kentucky teeing ground in a golf course in Gyunggi providence. Interestingly, blue-green algae from the leaf tissue sample containing black spot-stained symptoms were largely observed through microscopic study. In general, algae present on the upper soil surface or in the upper layer of root zone form dark brown layers of scum or crust, which invoked harmful effects to turf growth such as poor drainage, inhibition of new root development. In this observation, unlike the algae were sometime found in senescing leaves on contacted soil in July and August, the blue-green algae were detected within black spot-stained Kentucky bluegrass leaf tissues including leaf blade, ligule, auriclea as well as leaf sheath. The blue-green algae were also detected on the leaf and stem tissue adjacent to the symptomatic leaf tissues. Two species of blue-green algae, Phomidium and Oscillatoria, were greatly observed. Oscillatoria species was more commonly notified in all samples. In addition, the two species were found on a putting green showing yellow spot disease at another golf course in Gyunggi providence. The data from chemical control assay revealed that chemicals such as propiconazole, iprodione, and azoxystrobin decreased blue-green algae population and leaf spots, which finally resulted in enhanced leaf quality. All taken together, we strongly suggested that the disease-like phenomenon by blue-green algae might be very closely mediated with infection/ translocation process in relation with turfgrass. It indicates that blue-green algae in turf management may play an adverse role as a secondary barrier as well as a pathogenic agent. This report may be helpful for superintendents to recognize and understand the fact that algae control should be provided more cautiously and seriously than we did previously in upcoming golf course management.

한국잔디에 발생한 달라스팟 병의 주요 원인균인 Sclerotinia homoeocarpa의 동정 및 특성

박대섭,김경덕,염주립,오병석,박병선,Park Dae-Sup,Kim Kyong-Duck,Yeom, Su-Rip,Oh Byung-Seog,Park Byoung-Sun 한국잔디학회 2005 한국잔디학회지 Vol.19 No.2

위에서 골프장의 안양 중지 이병 잎에서 분리한 병원균인 달라스팟 유사 병원균을 분리 동정하였다. 2000년도 국내에 처음 보고된 이후 현재까지 뚜렷하게 진전된 연구가 보고 되지 않아 향후 사전 예방과 발생시 방제 법을 강구하기 위함과 아울러 코스관리자의 면밀한 관심을 유도하기 위하여 병원균 분리, 동정 및 특성을 한지형 잔디(Agyostis palustris Huds. cv Penncross)에서 발생하는 달라스팟 병원균과 비교 실험을 실시하였다. 1. 기존에 알려진 것처럼 Sclerotinia homoeocarpa 에서 보이는 온도에 대한 민감도를 새로운 병원성 Scz1 균주에서도 볼 수있어 특정온도에서의 생장억제는 안양 중지 달라스팟 병의 발병하는 시기뿐만 아니라 병방제관리에 도움이 될 것으로 생각된다. 2. 병원균 균사 특성에서 전자현미경사진으로는 구별하기 어려웠으나, PDA배지상에서의 Scz1와 Scz2 색상은 동일한 반면 Scb1균사색상과는 차이가 남으로 향후 간단하게 균사색상으로 식별이 용이 할 것이다. 3. 실험실상에서 병원균의 약제 민감도 측정결과는 이프로디온과 프로피코나졸 약제가 우수하였다. 4. 병 접종 실험을 통하여 분리된Sczl 균주가 안양 중지에 대한 기주 특이성을 보임으로 조이시아 달라스팟의 주요 병원균으로 밝혀졌다. 5. Scz1의 병원성은 안양 중지에 대한 기주 특이성이 높은 것으로 밝혀졌다. A fungal isolate was newly collected from Zoysiagrass 'Anyang-Joongji' in small circular patches on a fairway ofa golf course in Korea, which seriously occurred during the early summer period of 2005. The isolate presented on PDAmedium, named Scz1, was closely identical to Sclerotinia homoeocarpa, a casual fungus of dollar spot disease, in cool season turf grasses such as creeping bentgrass. Hereby, this study was accomplished to characterize the isolate and compare it with the fungus, named Scb1, isolated from dollar spot-infected creeping bentgrass (Agrostis palustris Huds. cv Penncross). On PDAmedium, individual mycelial appearance of three isolates was very similar except for the pigment. Mycelial pigments of Scz1 and Scz2 (another analogous isolate collected) were light pinkish on the reverse side of PDA medium but that of Scb1 was dark brownish. In a microscopic study, three isolates were barely distinguishable in the appearance of mycelia. As expected, in the temperaturesensitivity assay, all pathogens were very delicate to $32^{circ}C$ above but not to $30^{circ}C$ below, in which was explained to be one of typical characteristics in S. homoeocarpa. In an artificial inoculation assay, disease symptoms including leaf spots in Zoysiagrass were appeared within 6-7 days after inoculation through the hand inoculation method with the isolate-infested soil. Then the fungus was re-identified from the infected leaf tissues. Interestingly, inoculation of isolate Scz1 gave rise to distinct symptoms in only Zoysiagrass but not in creeping bentgrass 'Penncross' and Kentucky bluegrass 'Midnight'. The observation might be involved in host specific pathogenecity of S. homoeocarpa Scz1 to Zoysiagrass. In a chemical sensitivity assay for the isolate, Scz1, showed a high mycelial inhibition against two fungicides, iprodione and propiconazole. All results described above suggest that S. homoeocarpa Scz1 is a primary pathogen of Zoysia dollar spot disease.

This research carried out theory studies, set of hypothesis, and actural proof through examination on former researches. Customers who use traditional Korean food restaurants are chosen for the actual proof, and SPSS, statistics program, is used for verification of the research hypothesis. The results of the research can be summarized as follows. Firstly, statistically, all types of perceived equity positively affect customer satisfaction. In particular, from all types of perceived equity, interaction equity affected most positively. Following by distribution equity and procedural equity. Secondly, statistically, all types of perceived equity positively affect customer loyalty. Especially, from all types of perceived equity, interaction equity affected most positively. Following by distribution equity and procedural equity. Thirdly, customer satisfaction statistically affect customer loyalty. These results say kindness and agreeableness is most significant and important. In other words, employees' response attitude, kindness, consideration toward the customers and service handling from the customers' point of view are most necessary.

잔디 엽병을 유발하는 잠재인자로서의 남조류(Blue-Green algae)에 대한 관찰보고

박대섭,이형석,홍범석,최병만,전재찬,Park, Dae-Sup,Lee, Hyung-Seok,Hong, Beom-Seok,Choi, Byoung-Man,Cheon, Jae-Chan 한국잔디학회 2008 한국잔디학회지 Vol.22 No.2

본 연구는 아직 국내에서 보고된 바 없는 조류에 의한 잔디 병 발생 가능성에 대한 연구로, 2008년 7월 경기지역 골프장내 켄터키 블루그래스가 식재된 티잉그라운드에서 흑갈색 얼룩 반점병을 일으킨 잎조직이 발견되면서 조류에 의한 잔디 병 발생 요인과 대책을 조사하였다. 1. 켄터키 블루그래스의 흑갈색 반점 염조직으로부터 다수의 남조류(blue-green algae)가 관찰되었고, 흑갈색 반점이 형성 부위의 엽몸, 엽귀, 그리고 엽집에서 남조류가 다수 발견되었으며, 이병조직 이외의 개체내 건전부위와 줄기에서도 남조류 파편이 발견되었다. 발견된 남조류는 Oscillatoria 계통이 많았다. 2. 잔디밭에서 남조류는 토양 내 뿌리나 지제부에서 관찰되는데, 이번 관찰시에는 켄터키 블루그래스의 흑갈색 얼룩반점 병반부위인 상단 엽조직에서 남조류가 관찰되었다. 또한 이병조직 주위의 건전한 부위에서도 작은 파편형태의 남조류들이 발견되었다. 이것은 현재까지 식물조직 내 남조류의 이동경로에 대하여 알려진 바가 없지만 조직 내에서 남조류의 이동 가능성도 있다. 3. 흑갈색 얼룩반점이 형성된 켄터키 블루그래스 뿐만 아니라 황화현상이 발생한 벤트그래스 퍼팅그린의 잔디 잎에서도 남조류가 관찰되었으므로, 향후 초종에 따른 조류의 영향에 대한 세부연구가 수행되어져 야 할 것이다. 4. 약제처리로 조류 억제와 흑갈색 얼룩 반점 경감효과를 가져왔는데 프로피코나졸이 가장 우수하였고 이프로디온과 아족시스트로 빈 순으로 조류 억제가 관찰되었다. 6. 특히 고온 다습한 여름철에 조류 방제가 어렵고 적절한 조류억제제를 선택하기가 쉽지 않다. 이에 따라, 조류에 대한 일반적 관리에 머무르기보다는 더 적극적인 방제 방안 및 사전 예방 관리를 강구하여야 할 것이다. 6. 끝으로 향후 조류의 잔디 조직 내 이동 및 감염 경로를 규명하고자 하는 지속적인 연구가 진행되어야 할 것이다.
