This study is to establish the concept of using health care plants as a term representing the health promotion effect of plants. In order to establish and share the concept of terms, the perception of urban residents was investigated. The results of analyzing the responses of 726 urban residents are as follows. Plant cultivation at home has continued steadily since the past, and especially in the 40s and 50s, the 20s and 30s have become a new consumer as interest in the 20s and 30s has recently increased. Consumers are more sympathetic to changes in space and environment than to maintain health through plant cultivation. Respondents sympathized more with maintaining psychological health than physical health. Healthcare plants can be explained as plants that promote the maintenance and improvement of consumers' physical and psychological health through changes in space and environment by growing plants. Consumers recognize health care plants as environmental purification plants for health maintenance and improvement, and there was a difference from the concept of crops for consumption purposes. As the perception and understanding of the term healthcare plant is low, it is necessary to establish and promote a concept that many consumers can sympathize with. 본 연구는 식물의 건강증진 효과를 대표하는 용어로 헬스케어식물을 활용하는데 있어서 개념이 설정되지 않은 용어를 정의하고 공유하기 위하여 도시민의 인식을 파악하였다. 전국의 도시민 726명을 대상으로 온라인 설문조사를 실시하고 응답을 분석한 결과, 40-50대 중장년층을 중심으로 가정 내 식물 기르기를 통해 예전부터 꾸준히 지속되고 있으며, 최근 20-30대 젊은 층의 관심이 늘어나면서 새로운 소비자로 부상하였다. 소비자는 식물 기르기를 통해 신체적ㆍ심리적 건강의 유지ㆍ증진보다 공간의 분위기나 환경의 변화에 더욱 공감하며, 전반적인 건강 유지ㆍ증진에 관한 공감도는 신체적 건강보다 심리적 건강에 더욱 공감하였다. 헬스케어식물은 식물을 기르면서 느끼게 되는 실내 공간의 변화, 실내의 공기정화 등 가정 내 환경변화를 통해 소비자의 신체적 건강과 심리적 건강의 유지ㆍ증진을 도모하는 식물체를 총칭하는 것으로 설명할 수 있다. 소비자는 헬스케어식물을 신체적ㆍ심리적 건강의 유지와 증진을 도모하는 환경정화식물로 인식하여 섭취가 가능한 작물의 개념과는 차이를 보였다. 현재 헬스케어식물에 대한 인지는 식물의 기능적 측면 뿐 아니라 건강증진 효과에 대해서도 공감도가 높기 때문에 많은 수요자가 공감할 수 있도록 개념을 설정하고 홍보가 필요할 것으로 판단된다.

This This research was conducted to understand the growth characteristics of ground cover plants under different watering conditions and evaluate their growth recovery after moisture stress. Four species of succulents commonly used as ground cover plants were selected to determine the optimal planting spacing that achieves the purpose of ground coverage. Additionally, the changes in growth and ground covering rate were analyzed based on different watering treatments. There were variations in the optimal planting spacing required to achieve covering coverage for each plant: Mukdenia rossii required 30-35cm, Lampranthus spectabilis required 30-40cm spacing, Phlox subulata required over 40cm, and Sedum sarmentosum required spacing less than 20cm. Analyzing the growth characteristics based on watering treatments showed that continuous watering led to longer stems, but there were minimal growth changes during the treatment period. covering rates differed based on watering treatment and plant type. Lampranthus spectabilis and Mukdenia rossii showed covering recovery 20 days after no watering when watering resumed, while Phlox subulata showed covering recovery after some time had passed since watering resumed. Once covering was established, there were minimal changes in covering rates due to soil moisture scarcity. However, insufficient moisture during initial covering growth posed difficulties. Phlox subulata, Lampranthus spectabilis, and Mukdenia rossii could recover upon watering after a certain period of no watering. Therefore, while there are differences among species in plant care, proper watering management is crucial, and growth recovery can occur upon watering after a certain period of no watering.

In urban areas, the frequency of abnormal weather phenomena and various environmental issues is increasing due to climate change. To enhance urban resilience, there is a growing focus on nature-based solutions. Given the close relationship between vegetation and natural processes, there is a demand for plant materials that exhibit strong resilience to environmental stress. This study aimed to evaluate the flood tolerance of 47species of cover plants, providing basic data for the selection of garden plant materials. The target plants were completely submerged up to the shoot for 3 and 7days. Subsequently, they were managed using conventional methods, and their growth was observed over a 4-week period. Flood tolerance was categorized into 5groups based on changes in plant appearance and differences in the S/R ratio (Shoot/Root ratio) between the control and treatment groups. Group A, consisting of 28species such as ‘Ligularia Fischeri’, showed no changes in appearance, and the S/R ratio was 0.8-1.2 times, indicating that they were not significantly affected by flooding. Notably, 17species in Groups B, C, D, and E exhibited distinct changes in appearance and S/R ratio due to flooding. Among them, four species, including 'Dendranthema zawadskii', displayed significant changes in appearance, with an S/R ratio four times that of the control group (Group C). Additionally, 'Aruncus dioicus' experienced complete withered (Group E). Based on these results, it is appropriate to consider plants in Group A when selecting plant materials that can withstand flooding. 도시 내 기후변화로 인한 이상 기상 현상과 함께 다양한 환경문제의 발생 빈도가 높아지고 있다. 도시의 회복력 향상을 위해서 자연기반해법이 대두되며, 이는 식물의 생육과 밀접한 관련이 있으므로 환경 스 트레스에 회복력이 강한 식물 소재가 요구되고 있다. 본 연구는 식물 소재 중 지피식물 47종을 대상으로 침수 내성을 평가하여 식재 및 관리를 위한 기초자료로 활용하고자 수행되었다. 시험 식물을 3일 및 7일 간 지제부까지 완전히 침수시킨 후 관행의 방법으로 관리하여 생육 변화를 4주간 관찰하였다. 식물의 외관 변화와 대조구와 처리구간의 S/R율(Shoot / Root ratio)차이에 따라 내침수성을 5개 집단으로 구분 하였다. Group A는 ‘곰취’등 28종의 식물로 외관 변화가 없으며, 침수에 의한 영향을 받지 않는다. Group B, C, D 및 E의 17종은 침수에 의한 외관 변화나 S/R율의 차이가 뚜렷이 확인되었다. 특히 ‘구절초’등 4종은 외관의 변화가 뚜렷하고 대조구와 처리구간 S/R율이 4배 수준이며(Group C), ‘눈개승마’는 지상 부가 완전히 고사하였다(Group E). 따라서 침수에 대응한 식재 계획에서는 Group A의 식물을 이용하는 것이 적합할 것으로 판단된다.

고바울(Baul Ko),김호철(Ho Cheol Kim),구양규(Yang Gyu Ku),김철민(Chul Min Kim),배종향(Jong Hyang Bae) (사)한국생물환경조절학회 2020 생물환경조절학회지 Vol.29 No.3
본 시험은 저면관수 방식의 파프리카묘 육묘 시 암면큐브에 대한 다양한 급액시점 (IP 30%, 40% 50%, 60% 및 70%)에 따른 파프리카 묘의 소질을 조사하였다. 급액시점에 따른 파프리카 묘의 생육량은 급액시점과 정의상관을 나타내었다. 특히 IP 30~40% 처리구와 IP 50~70% 처리구들 간 뚜렷한 차이를 나타내었다. 엽면적은 50% 이상의 처리구에서 40%이하의 처리구에 비해 50~100%정도 더 넓었고, 건물중도 30%~60% 정도 더 무거웠다. IP 50% 이상 처리구에서 건물중의 유의한 차이는 없었다. 급액시점(X)은 파프리카 묘의 엽면적(Y₁)과 Y₁=48.311X+133.7(R² = 0.9116**), 건물중(Y₂) 과는 Y₂=0.1584X+0.8616(R² = 0.8853*)의 선형회귀관계를 나타내었다. 따라서 본 연구 조건에서 파프리카 육묘 시 처리 간 엽면적과 건물생산량을 고려하였을 때 암면큐브의 함수율 50%에 급액하는 것이 적절하고 경제적일 것으로 생각된다. This study was conducted to investigate the seedling qualities and growth of paprika according to various irrigation points (IPs) (30, 40, 50, 60 or 70%) compared to the weight of rockwool cube with 100% water content for raising seedlings of paprika. Growth degree of paprika seedlings was positively correlate with various irrigation points. In particular, paprika seedlings with IP 30-40% and IP 50-70% treatments were significantly higher than those with other treatments. Leaf area of seedlings was 50-100% wider in those with IP 50% and IP 40% treatments than those with other treatments, therefore dry weight was heavier in IP 30-60% treatments. The dry weight of more than IP 50% treatments had no significant differences. Leaf area (Y1) had a significant relation with the irrigation point (x) as Y1 = 48.311x + 133.7 (R2 = 0.9116**). Also dry weight (Y2) of the seedlings showed a linear regression equation as Y2 = 0.1584x + 0.8616 (R2 = 0.8853*). Considering the leaf area and the dry weight of irrigation points for rising seedlings of paprika in this study, the optimum range of the irrigation points in the water contents of rockwool cube is IP 50%.
