Korean Poaceae includes approximately 80 species of the agricultural weeds. Precise species identification is the first step for more effective weed management in the agricultural fields. However, the identification of species in Poaceae is not easy without the assistance of taxonomists or identification experts although they are relatively easy to distinguish from the plants of the other family by the unique characteristics of caryopsis. Thus, DNA barcode was suggested as an alternative powerful technique for species identification by using short sections of DNA from a specific region of the genome. Two standard barcode markers of vascular plants, chloroplast rbcL and matK, and a supplementary nuclear ribosomal Internal Transcribed Spacer (ITS) region were used for barcode of major Korean Poaceae weeds, 403 individuals of 84 taxa. All the barcode markers revealed a good level of sequencing success with the lowest 73.7% for matK and the highest 88.8% for rbcL. The barcode sequences were deposited to the National Center for Biotechnology Information (NCBI) database for public use. Combined matK and ITS showed very high resolving power with 92.9%. Besides the identification of weeds for weed managment, the generated DNA barcode data could be used for many other applications such as rapid biodiversity assessment and conservation prioritization.

Two naturalized species, Glyceria declinata $Br{\acute{e}}b$. and Puccinellia distans (Jacq.) Parl. are herein newly reported from Korea. Glyceria declinata, 'Yu-Reop-Yuk-Jeol-Bo-Ri-Pul', was found along the Seomjin River, Gurye-eup, Gurye-gun, Jeollanam-do, as well as along the Gwangjucheon River, Sa-dong, Dong-gu, Gwangju. It is distinguished from G. acutiflora by spikelets 15-20mm long and obtuse lemma. Puccinellia distans, "Cheo-Jin-Mi-Kku-Ri-Gwang-I", was found in Yeongjong Island, Incheon, Yongyu Island, Incheon and Chojijin, Ganghwa-gun. It is distinguished from P. nipponica by lemmas 1.8-2.5mm long, ligule 1-2mm long and the lower branches of panicle usually reflexed after anthesis.

Echinochloa oryzoides (Ard.) Fritsch (Na-do-non-pee), was found at paddy fields of Jeonranamdo on a large scale after a first discovery at Masan, Kyeongsangnamdo. This species was not easily distinguished from rice before flowering at the paddy field because of a similar morphology to rice. It is, however, distinguished from other species of the Korean Echinochloa by reliable morphological characters such as horizontal or drooping panicles at maturity, lower glumes with usually 1/4-2/5 as long as the spikelets, awned lower lemmas, and the number of chromosomes, 2n = 54. Echinochloa oryzicola (Vasinger) Vasinger was distinguished from E. oryzoides by erect panicles, lower glumes with at least 1/2 as long as the spikelets, and the number of chromosomes, 2n = 36.

Two unrecorded Poaceae species, Anthoxanthum glabrum and Saccharum arundinaceum, are herein newly reported from Korea. Anthoxanthum glabrum (Ae-Gi-Hyang-Mo) was found in Ansan-si, Gyeonggi-do, Sangju-si, Gyeongsangbuk-do and Hwasun-gun, Jeollanam-do. It is distinguished from A. nitens by the length of its spikelet, glume and lemma. Saccharum arundinaceum (Keun-Gae-Sa-Tang-Su-Su) was found in Mapo-gu, Gangnam-gu, Seoul, and Hwasun-gun, Jeollanam-do. It is distinguished from S. spontaneum by hair on the lower glume and according to the length of the hair on the callus of its spikelet. In this study, a description and illustrations of the species and photos of the habitat are provided.

This study aims feeding habit of the Korean water deer(Hydropotes inermis argyropus) using a visual analysis of rumen contents of 44 individuals. The samples were collected from Cheorwon(Gangwon province) and the eastern part of Jeonnam province. Based on the analysis, a total of 15 orders, 18 families and 13 species were identified. Among them, Solanceae(53.8%) and Graminease(30.3%) showed the highest proportions. Plants of 13 orders, 15 families and 10 species were found and forbs(70.21%) and Solanceae(54.9%) were most preferred in Cheorwon. Eight orders, 7 families and 4 species were found in the Eastern parts of Jeonnam province, and Gramineae(78.6%) and woody plants(14.70%) was most preferred. Among four seasons, Gramineae in spring(80.6%) and autumn(68.8%), Leguminosae(75.9%) in summer, and Solanceae(85.4%) in winter were the highest proportions.

In this study, we surveyed the distribution pattern and dominance of weeds occurred in four summer crop fields, hot pepper, soybean, maize, and Chinese cabbage in Gyeongbuk province. The weeds were summarized as 32 family and 132 species in hot pepper field, 31 family and 116 species in soybean field, 37 family 134 species in maize field, finally 35 family and 170 species in Chinese cabbage field. Among these weeds occurred in the four summer crop fields, the compositae was commonly dominant family, it occupied 17.4% in hot pepper field, 18.1% in soybean field, 11.9% in maize field, and 16.5% in Chinese cabbage field. The major five families including compositatae, graminae, polygonaceae, convolvulaceae and cruciferae were occupied 43.2% in hot pepper field, 47.4% in soybean field, 42.5% in maize field, and 43.5% in Chinese cabbage field, respectively. Furthermore, the most dominant weed in the hot pepper, soybean, maize, and Chinese cabbage fields was Portulaca oleracea, Digitaria ciliaris, and Rorippa palustris, respectively. This information could be useful for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods in food crop fields of Gyeongbuk province.
