The present study analyzes the diversity and usage of NTFPs and evaluates their importance in the day to day life of the people of rural Meghalaya. People use 172 NTFPs belonging to 139 plant species mainly for food, medicine and fuelwood and to a lesser extent for construction, handicrafts and ornamental purpose. These 139 plants belonged to 117 genera and 70 families with Rosaceae, Poaceae and Fagaceae families as the dominant NTFP yielding families. Fruits from shrubs and trees are most commonly harvested by people. Collection and availability of NTFPs for use as food are more during the summer season, which is also the period with least availability of job. NTFPs for subsistence use are greater in number than those having commercial value. The most commonly harvested plant parts are fruits and leaves. Roots, rhizomes and whole plants are extracted in lesser quantity which is a positive approach from sustainability point of view. NTFPs and other forest products also form a vital part of the rural household's income generation activities.

Here we reported two unrecorded naturalized species from Korean flora. Andropogon virginicus L. of Graminaeae and Euphorbia postrata Aiton of Euphorbiaceae are collected from Dong-gu, Ulsan-si and Sinjindo-ri, Taean-gun, Chungcheongnam-do respectively. A. virginicus L. was easily distinguishable from Themeda triandras var. japonica Makino by keel on glume, 2-4 racemes and long hairy rachis. Thus, the new Korean name, 'Na-do-sol-sae', was given. E. postrata Aiton was cleary distinguished from related taxa by hairs on only edges of fruits. The new Korean name, 'Nu-un-ttang-bin-dae' was given considering the species epithet. Descriptions, illustrations and photographs showing habitat were given.

Long-term culture of cell lines is an important issue in in vitro culture and in plant science. In this study, the regeneration ability and ex vitro acclimatization of regenerants were evaluated. The ploidy level of regenerants derived from long-term cultured cell lines was measured in Imperata cylindrica 'Rubra', Poaceae. Adventitious buds (shoots) were successfully induced from five-year-cultured calli on MS medium containing 0.1 mg/L BA or 2.0 mg/L TDZ, combined with 0.01 mg/L auxins (IAA, IBA, NAA and 2,4-D), respectively. Adventitious roots were also induced on MS medium containing 0.01 mg/L auxins (IBA, NAA and 2,4-D), respectively. Interestingly, regenerants with both red and green leaf were successfully obtained when regenerants were cultured on MS medium with 9% sucrose. Regenerants derived from long-term cultured calli were transferred to pots using an optimal acclimatization process and successfully adapted to both pot and soil conditions. Moreover, the ploidy level was measured using calli and regenerants that had been kept on MS medium containing various kinds of plant growth regulators (PGRs).

국내 미기록 식물인 성긴포아풀(Poa tuberifera Faurie ex Hack.)을 제주도 제주시 조천읍 사려니숲에서 확인하였다. 근연분류군인 실포아풀(P. acroleuca Steud.)과 마디포아풀(P. acroleuca var. submoniliformis Makino)에 비해 화서에 소수가 성기게 달리고, 호영 기반에 털이 없는 특징으로 구별된다. 성긴포아풀은 일본의 고유종으로 알려져 있으나, 국내분포가 이번 연구에서 밝혀졌다.

Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.

Vulpia octoflora (Walter) Rydb.가 경기도 여주시 강천리 일대에서 발견되었다. 본 종은 북아메리카 원산으로 알려져 있으며, 최근 호주와 일본, 우크라이나에서 침입외래식물로 보고된 바 있다. V. octoflora는 주로 건조한 건조한 모래나 자갈 모래밭에 자라는 잡초성 식물로, 도로변을 따라 개방된 지역이나 인위적 교란 지역에서 빈번하게 발견된다. 학자에 따라 북아메리카 지역에 분포하는 개체들의 지리적 분포와 형태 변이를 근거로 종하분류군으로 세분화하기도 하지만, 형태 변이의 일관성 부족으로 인해 종내 변이로 인식하여 통합하여 처리하는 것이 타당하게 여겨진다. 본 종은 최근에 국내에 보고된 침입외래식물인 들묵새아재비와 유사하나, 소수당 달리는 소화의 수가 더 많고, 호영 정단부의 까락의 길이가 짧은 것으로 명확히 구분된다. 좀들묵새에 대한 생태계 위해성 연구는 진행된 바 없으나, 최초 발견지인 여주시 강천섬 일대는 멸종위기 2등급종인 단양쑥부쟁이의 자생지이기 때문에, 새롭게 유입된 외래식물의 잠재적 생태 교란에 따른 위해성 평가 및 확산 방지를 위한 모니터링이 필요할 것으로 여겨진다. 본 연구에서는 주요 형질에 대한 기재와, 지리적 분포, 도해도, 화상자료와 국내에 분포하는 동속 분류군과의 검색표를 제공하고자 한다.

A vascular flora survey was conducted in 2020 to identify flora and analyze changes in the numbers of vascular flora species over the past 10 years at Gongju-weir (GW) and Baekje-weir (BW) in the Geumgang River, Republic of Korea. A total of 241 taxa were found in GW and 279 taxa in BW, and 208 taxa (88% of total taxa) were common species. The distribution of invasive species in GW and BW were seven and eight taxa, respectively. Rare plants were not identified in any of the weirs. The Poaceae family dominated in terms of number of species, followed by Asteraceae, Legumes, Cyperaceae, and Polygonaceae. Additionally, Therophytes accounted for a high proportion of Raunkiaer life forms. The numbers of vascular plant species, total taxa, naturalized plants, and invasive species have been increasing over the last 10 years. However, long-term alterations in invasive species before and after the opening of the weirs increased much more significantly in the partially opened BW than in the fully opened GW. These results indicate that the degree of barrier opening does not affect the invasion and establishment of non-native species.
