This study was carried out to provide recent information on zoysiagrass (Zoysia spp.) sod production in Japan. Total zoysiagrass sod production acreage in Japan was 6,623 ha. The acreage by prefecture was 3,900 ha (58.9%) in Ibalaki, 779 ha (11.8%) in Tostoli, 609 ha (9.2%) in Kagosima, and 550 ha (8.3%) in Sijeumoka, respectively. Sod was harvested by 1.5 cm sod thickness. Mowing height of Goraisiba (Zoysia matrella) and Nosiba (Zoysia japonica) cultivars was cut by 10 mm and 25 mm height, respectively. Japan agricultural cooperative issued a warranty of sod production quality to zoysiagrass consumers. A quality evaluation for sod production was carried out continuously to maintain a reasonable degree of uniformity and hight quality of sod production three times a year. Also, zosiagrass sod production was rotated with Chinese cabbage (Brassica rapa var. glabra Regel) for improving fertility of soil every five to six years. Patented cultivars for promoting bland in Ibaraki prefecture of Japan were 'Tsukuba himae', 'Tsukuba kagayaki', 'Tsukuba Talou' and 'Tsukuba green'.

The 2011 Japanese Society of Turfgrass Science was divided in oral presentation, sectional meeting and small symposium, and the total 55 subject was announced. The oral presentation was reported physiological ecology of turf, disease and weed; field management; pesticidal activity and spectrum of new turf pesticides. Above all, there was presentation that investigated control method of necrotic ring spot of new turf disease and Cyperus brevifolius, annual bluegrass and mouse-ear chickweed. In addition, the control effect of new registration fungicide (Furametpyr) and herbicides (S-metolachlor, Flucetosulfuron and Foramsulfuron) were announced. There was various information interchange through 4 kinds of subjects of a golf course, ground turf, a urban park greens and ground cover plants greening by the sectional meeting, and the genetic resource of turfgrass discussed by small symposium. Specially, park greens sectional meeting was announced about the radioactive material contaminated on mechanism and effectively removal method of the radioactivity contaminant from public park, school ground and domestic lawn.

Desmodium paniculatum (Fabaceae), native to North America and an alien plant in Japan, was newly found in Hwaseong-si and Daejeon-si, Korea. This species is distinguished from Korean-related taxa based on certain morphological features. Specifically, it is a perennial herb, with a 4-5 jointed loment, and with the basal suture moderately incised between the articles. In the field, D. paniculatum grows around rivers and roadsides, suggesting that it is likely to have been introduced through river improvement work and road construction. On the phylogenetic tree based on an internal transcribed spacer, Korean individuals forms a clade with a Japanese individual. Here, we report a morphological description, photographs, an illustration, and the locality of D. paniculatum.

동아시아와 북미에 분포하는 조경수목을 형태적 특성 및 분자생물학적 특성에 따른 연구 결과를 토대로 분류한 결과 8종에서 밀접한 관련성을 갖고 있었다. 자주받침꽃, 능소화, 산딸나무, 보리밥나무, 가래나무, 튤립나무, 일본목련, 잣나무는 동아시아와 북미에서 각각 밀접한 유연성을 가진 종들이 있어 이들을 조경수목쌍으로 분류할 수 있었다. 그리고, 형태적 특성이 매우 흡사한 종으로는 중국단풍나무, 고로쇠, 들메나무, 야광나무, 소나무와 곰솔, 상수리나무, 갈참나무, 떡갈나무, 신갈나무, 굴참나무, 피나무, 참느릅나무 등에서 동아시아와 북미 조경수목쌍이 존재하는 것으로 판단되었다.

This study was carried out to assess the present condition of domestic and foreign patented technologies in turfsrass cultivar area. Patented technologies about turfsrass were analyzed by web site(www.kipris.or.kr) from 1948 to 2005. The results are summarized as follows; 1. Number of patents on turfgrass fertilizer(866) was more than the other patents on turfgrass. 2. Total number of Japan's patents on turfgrass was 1,565. This is more than America's. The foreign patents are mostly on cultivar, sod, seed, disease, construction, and management. 3. Number of patents from company(2,328) was the most and the others are private individuals, research institutes, university professors. However commercialization rate of patants was low. 4. Turfgrass cultivars patented in Korea are 'Konwoo', 'Senock' 'Anyanjungji', etc., and in foreign countries 'Zenith', 'Miyako', etc. Among them 'Zenith', 'Miyako' and 'Konhee' were commercialized.

This study was conducted to investigate the effect of Actinomyces sp. and Bacillus sp., United States granular microorganisms and Japan granular microorganisms on turfgrass growth and thatch decomposing of creeping bentgrass in golf course by measuring turf color index, chlorophyll index, thatch content of soil, root length, turf density and chemical properties and thatch content of soil. Fertilizer treatment was designed as follows; control(CF; compound fertilizer), microorganism medium(M; CF+M), microorganism medium and livestock manure fertilizer(M-L; CF+M+LMF), microorganism medium, livestock manure fertilizer and amino acid liquid fertilizer(M-L-A; MM+LMF+ALF), United States granular microorganisms(USGM; CF+USGM), Japan granular microorganisms(CF+JGM). 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 M, M-L, M-L-A, USGM, JGM treatment were higher than those of CF. The turfgrass root in M-L treatment was longer than others. The thatch content of soil in M treatment was longer than others. The thatch content of M was decreased than that of CF by 6.8%. These was suggested that application of M induced the development of quality and growth of creeping bentgrass by assisting turfgrass growth and thatch decomposing.
