Native plants thrive naturally in specific areas without human intervention, offering significant potential as genetic resources and biotechnological assets across multiple sectors. To harness this potential, our focus was on analyzing domestic patents related to native plants, investigating their uses, effectiveness, active components, and extraction methods. Using the Korea Forest Service's National Standard Plant List, we gathered data from 988 patents on native plants and 430 patents on the use of native plant seeds. This comprehensive patent analysis aimed to reveal research patterns, technology levels, and emerging trends. The goal is to identify research trends, current technology levels, and provide insights for future patent applications involving native plants.

전 세계에 유통되고 있는 Cypripedium속 식물 56종 중 한반도에는 4종이 분포하고 있다. 국내의 Cypripedium속 식물 중 멸종위기 1급 식물은 광릉요강꽃과 털복주머니란이 있으며, 복주머니란은 멸종 위기 2급 식물로 분류하였다. 본 연구는 이러한 복주머니란 식물의 육묘기술을 개발하기 위하여 연구를 수행하였다. 처리는 원예용 상토, 마사토 100%, 질석 2 : 펄라이트 1의 비율로 혼합한 인공토양, 산야초 상토, 소립인 난석 등 5처리를 하여 복주머니를 스티로폼 박스(가로 40, 세로 50, 높이 15cm)에 식재하여 4개월 경과 후 조사한 결과 산야초 상토에서 출아율이 67.0%로 가장 많았으며, 질석 2 + 펄라이트 1의 처리구가 53.0%, 소립인 난석 처리구가 48.0%순으로 높았다. 출아율이 가장 좋았던 산야초 상토의 경우 초장은 3.0cm, 엽수는 주당 1.9개, 엽폭은 1.0cm로 다른 처리구보다 생육이 양호하였다. 또한 털복주머니란 실생묘를 노지에서 1년 동안 순화한 묘를 자생지 외 지역의 적응성을 확인하기 위해 경기도 양평에 위치한 국립수목원 내 Cypripedium 전문 전시원에 660주를 봄에 식재하였다. 그해 9월에 생존율 을 조사한 결과 52.5% 이었고, 초장이 5.8cm, 뿌리수는 주 당 3.6개, 뿌리길이는 6.4cm 등 생육도 정상적으로 진행되는 것으로 조사되었다. 이와같은 연구를 바탕으로 멸종위기종인 복주머니란의 적정 환경 조성과 육묘기술 및 현지 적응성을 향상시킨다면 멀지 않은 시기에 복주머니란의 복원 사업은 성공적으로 마무리될 것으로 판단된다..

Vascular plants of Yeonhwasan Mt., located in Taebaek-si, Gangwon-do, were investigated. Field surveys were conducted fourteen times between April and September of 2022. A total of 505 taxa were found consisting of 87 families, 282 genera, 441 species, 15 subspecies, 41 varieties, and 8 forma. Among them, the endemic plants of Korea were 22 taxa. The number of threatened and near threatened Red List plants designated by the Korean National Arboretum was four, comprising each one of critically endangered (CN), endangered (EN), vulnerable (VU), and near threatened (NT) species. The number of floristic target plants designated by the Ministry of Environment was 102, including one taxon of level V, 9 taxa of level IV, and 34 taxa of level III. Invasive alien plants were 34 taxa, and three taxa were ecosystem disturbance plants. The urbanization index of investigated site was 12.8%, and the naturalization index was 6.7%. To wisely manage Yeonhwasan, measures for preserving biodiversity and preventing invasive plants are needed.

지역의 역사성을 지니고 발전한 전통색은 지역 문화와 자연환경에 영향을 받는다. 전통색은 일반적으로 관용색명으로 표현하는데, 이는 세계인의 공용어가 아니므로 우리의 천연염색을 국내외 일반인과 공유하기 위해서는 표준화된 색명(KS-계열색, RGB, CMYK)을 사용하는 것이 필요하다. 우리나라에서 염료재로 활용된 염료식물은 393종으로 알려져 있다. 본 연구에서는 염료식물의 자원 활용과 그 보전적 가치를 알리고자 염료식물을 언급한 고문서 및 현대자료를 바탕으로 사용 부위, 매염제의 종류, 염색 시 발현 색상의 관용색명을 조사하였고, 이를 국가표준색상환에 대입하여 표준화에 대한 방향성을 제시하고자 한다. 연구 결과에 따르면, 염료식물 393종 중 관용색명을 가진 염료식물은 312종이었고, 관용색명의 정보가 없는 식물은 81종으로 나타났다. 염료식물의 사용 부위 정보를 가진 식물은 187종이었고, 이용부위는 식물체 전체(전초), 뿌리, 줄기(껍질), 줄기(심재), 나뭇가지, 잎, 열매(껍질), 꽃이었다. 염료식물에 활용되는 매염재는 15가지(천연 6종, 화학 9종)로 나타났다. 관용색명을 가진 염료식물 312종에서 조사된 540개 관용색명을 표준화 시키기 위하여 국가표준색상환에 대입한 결과, 표준화된 색명(KS계통색명, RGB, CMYK)을 갖는 식물은 127종, 관용색명은 있지만 표준화된 색명을 확인할 수 없는 식물은 185종인 것으로 나타났다. 향후 염료식물을 연구하는데 있어서 관용색명의 정보가 없는 염료식물에 대한 표준화된 색명을 찾아내는 연구가 이루어져야 할 것이다.

This study was conducted to prepare basic data by analyzing the biological values and environmental factors of algific talus slope in order to respond to climate change due to the greenhouse effect, and to establish plans for forest biodiversity preserving and managing. Meteorological information was measured and the flora of vascular plants were investigated for six algific talus slope by seasonally from 2020 to 2021. As a result of the investigation, the temperature of all 6 algific talus slope was lower than that of the area where the algific talus slope was located in summer, and flora was 101 families, 350 genera, 621 species, 18 subspecies, 57 variants, 7 varieties, 703 taxa. In sum, it is judged that the algific talus slope has sufficient reasons and value to be preserved because it has excellent micrometeorological value from the cold wind blowing in summer and phytogeographical value in which various plants live in a small area. However, in spite of such an important area, the management of algific talus slope is insufficient, and the algific talus slope is damaged or the ecosystem of the algific talus slope is disturbed. Therefore, it is necessary to establish a systematic conservation and management plan by designating algific talus slope as a forest genetic resource reserve and OECM.

Veronica rotunda var. subintegra (Nakai) T. Yamaz. is perennial herb belonging to the family Scrophulariaceae, native to Korea. Plant growth regulators, cutting mediums, cutting position, and leaf size were examined to investigate the requirements for cutting propagation of V. rotunda var. subintegra. This study was conducted over a period of 6 weeks from March to May 2017 in the Division of Plant Resources, Korea National Arboretum. For all treatments, survival and rooting percentage was 100%. In PGRs experiment, the number of roots and shoot length treated with 100 mg/L IBA treatment was significantly higher than that of NAA treatment. The shooting percentage was decreased with an increase of the PGRs concentration. In growing substrates experiment, the number of roots on commercial soil (61.2) was the highest, followed commercial + kanuma soil (45.7), and the lowest was kanuma soil (41.8). The shoot length treated with commercial soil (8.9 cm) was significantly greater than that of kanuma soil (4.1 cm). In cutting positions experiment, the number of roots treated with apical (56.6) was significantly higher than that of basal (38.8). In leaf-cut experiment, the number of roots and of shoot length treated with full leaf was significantly higher than that of half leaf. As a result, we recommend treating cuttings with 100 mg/L IBA treatment, commercial soil, apical position, and full leaf for successful cutting propagation of V. rotunda var. subintegra.

This study was investigated to find out the distribution of vascular flora and remarkable plants and its factors and management plan in the forest genetic resource reserve of Mt. Munsu, located in the DMZ and DMZ border area in Gimpo, Gyeonggi-do province. The survey was carried out 17 times from April 2019 to October 2020. First of all, in the forest genetic resource reserve of the Mt. Munsu, a total of 444 taxa in 95 families, 276 genera, 395 species, 13 subspecies, 33 varieties and 3 forms. This result was found to be about 9.09% of the total 4,881 taxa of vascular plants in Korea. In addition, endemic plants were classified as 6 taxa. Floristic special and rare plants were identified as 39 taxa and 3 taxa, respectively. Lastly, the invasive alien plants that appeared in Mt. Munsu of the forest genetic resource reserve were observed in 58 taxa. Moreover, the naturalization rate was 13.1% and the urbanization index was calculated to be 18.0%. As a result of comparing the vascular flora at the forest genetic resource reserve on Mt. Munsu identified in this study with previous studies, it was found the number of taxa was decreased compared to the previous studies, despite the fact that the recent survey section was wider and more varies routes were investigated. In particular, it was confirmed that the number of rare and endemic plants decreased significantly, and the number of invasive plants greatly spread to forest roads and hiking trails. Therefore, it is considered that the forest rest year system should be introduced for the conservation and management of native plants in the forest genetic resource reserve.

We report a technique for obtaining seeds of 'Cheongnarae' (a variety of Hosta minor cultivated at the Korea National Arboretum in 2019) by artificial crossing of H. minor, collected from Jeju Island, as the female parent and H. minor 'Krossa Regal', cultivated outside Korea, as the male parent. Among the individuals obtained after sowing, those that showed different morphological characteristics, such as leaf shape and color, were selected. Among these individuals, those with thick leaves and light-colored flowers were further selected. Vegetative propagation and cultivation steps were repeated for evaluation of the characteristics. 'Cheongnarae' has relatively thicker leaves and a darker color (RHS 137A) than the control variety 'Black Hills' and has wings at the point where the petiole meets the leaf blade. The shape of the leaf blade edge is clearly sinuous, and the flower color is close to white (White N155B). 'Cheongnarae' cultivated in this way can be used for pot plant or gardening.
