- The natural population of Cladrastis platycarpa (Max.) Makino (Fabaceae) was only found at the Arboretum of Chungbuk National University up to dates in Korea. In this study, we investigated the antioxidative effect of this unknown plant by different conditions of collection timing (May, July, and September), extracting solution (distilled water and ethanol) and tissues (leaves, branches, and flowers). The lyophilization yields of extracts was higher in ethanol extraction than water extraction as well as in summer and autumn season collection then spring one. DPPH radical scavenging activity of extract by distilled water showed a strong antioxidative effect than ethanol extraction, but the extract collected in July was lower than the others. In the combination of collecting time and tissues, the extract from the branches collected in May and July and the leaves sampled in September showed high antioxidant effects. In addition, the total polyphenol contents were also higher in water extraction except the branches collected in July and September. From the results, it was suggested that the extract of Cladrastis platycarpa has a high potential for natural antioxidant resources. It was also proposed that the target tissues and the extraction methods should be differently applied by the seasons to obtain enough amounts of extract. - COLLAPSE

- This study evaluated the antioxidant and photoprotective effects of Pinus rigida cone extract (ECRT) in UVB-irradiated Hs68 human dermal fibroblasts. Antioxidant capacity was measured using DPPH and ABTS radical scavenging assays, showing a dose-dependent increase with activity comparable to L-ascorbic acid at concentrations above 40 μg/mL. Cytotoxicity assays confirmed that ECRT was non-toxic to Hs68 cells at 25–400 μg/mL. Upon UVB exposure, DNA damage markers γ-H2AX and p53 were significantly elevated, but ECRT treatment reduced their expression in a concentration-dependent manner, demonstrating DNA protection. Additionally, ECRT inhibited UVB-induced expression of matrix metalloproteinases MMP-1, MMP-3, and MMP-9, which are key enzymes involved in skin aging and wrinkle formation, with notable suppression at 100–200 μg/mL. These findings indicate that ECRT not only scavenges free radicals but also protects dermal fibroblasts from UVB-induced oxidative damage and photoaging. Consequently, Pinus rigida cone extract shows promise as a safe, effective, and eco-friendly ingredient for skin photoprotection and anti-aging applications. - COLLAPSE

- This study was conducted using response surface analysis to confirm the optimal extraction conditions for efficient supply of polyphenol compound, which are indicator components of Persicaria chinensis, which is being developed as a resource plant. An experiment was performed on 17 sections using hot air dried leaves of P. chinensis by setting three independent variables (ethanol concentration, extraction time, extraction temperature) and the contents of neochlorogenic acid, corilagin, geraniin and ellagic acid were measured. The optimal extraction conditions for neochlorogenic acid were 19.2% ethanol concentration, 27.1 h extraction time, and 75°C extraction temperature. The expected value was 5.90 ㎎/g, and the experimental value was 5.82±0.25 ㎎/g. The optimal extraction conditions for geraniin were 41.5% ethanol concentration, 16.6 h extraction time, and 51.4°C extraction temperature. The expected value was 5.84 ㎎/g, and the experimental value was 5.95±0.44 ㎎/g. The optimal extraction conditions for ellagic acid were 80% ethanol concentration, 30 h extraction time, and 75°C extraction temperature. The expected value was 5.67 ㎎/g, and the experimental value was 7.45±1.25 ㎎/g. It was confirmed that neochlorogenic acid, geraniin and ellagic acid could be efficiently secured through optimal extraction conditions derived by response surface analysis. - COLLAPSE

- ‘Eunha’ is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2023. The ‘Eunha’ cultivar originates from a 2016 cross between ‘Portola’ and ‘Goha,’ both of which exhibited excellent ever-bearing characteristics, including continuous flowering and large fruits under long-day and high temperature conditions. This new cultivar was initially named ‘Saebong No. 15’ after examining its characteristics and productivity during summer cultivation between 2017 and 2022. After regional adaptability tests, ‘Eunha’ was selected from ‘Saebong No. 15’ as an elite cultivar. The general characteristics of ‘Eunha’ include semi-upright type, and strength vigor in growth. The fruits are conical and of a red color. The plant height of ‘Eunha’ is simliar to that of the control variety, ‘Goha’, but it has a lot of number of leaves. The number of flower clusters of ‘Eunha’ was 9.5, 4.6 less than 14.1 of the control variety. The average fruit weight of ‘Eunha’ was 12.2 g, which was 2.6 g heavier than that of ‘Goha’. The soluble solid content of ‘Eunha’ was 10.9 °Brix, which was 1.0 °Brix higher than that of ‘Goha’. The marketable yield of ‘Eunha’ was 27,499 ㎏·㏊-1, 153 % more than that of ‘Goha’ with 17,911 ㎏·㏊-1. Therefore, the new cultivar of ever-bearing strawberry ‘Eunha’ is expected to improve income when supplying farms as it has high soluble solid content and can be produced stably at high temperatures. - COLLAPSE

- In order to select great cultivars to grow in rice paddy fields in the southern region on spring season, growth, seed yield and organic components, and germination characteristics were investigated for four mungbean (Vigna radiata (L.) Wilczek) cultivars (‘Areum’, ‘Dado, ‘Dahyun’, and ‘Sanpo’). The flowering time was about 55 days after sowing. Harvesting time was 84 days after sowing for ‘Areum’ and ‘Dado’, and 98 days after sowing for ‘Dahyun’ and ‘Sanpo’. Mungbean cultivation in the paddy field improved the physical and chemical properties of paddy soil, that is, it increased the air phase, resulting in the porosity increase and the bulk density decrease, and increased the contents of the soil organic matter and the exchangeable cations (Ca2+, Mg2+, and Na+) slightly. Seed yield was high above 247 ㎏/10a in all three cultivars except ‘Dahyun’. Furthermore ‘Dado’ and ‘Sanpo’ are more resistant than ‘Areum’ and ‘Dahyeon’ to lodging caused by rain and/or wind. The proximate composition of the seeds are great in the order of carbohydrate > protein > moisture > ash > crude fat, and carbohydrates accounted for more than 50% of all four cultivars. The seed germination rate and vegetable sprout yield were the highest in ‘Dado’, but slightly low in ‘Sanpo’. Based on these results, mungbean cultivation in paddy fields improves the physical and chemical properties of the soil, and ‘Dado’ and ‘Sanpo’ are resistant to lodging and have high seed yields. Therefore, ‘Dado’ and ‘Sanpo’ seem to be favorable for cultivation in rice paddies in the southern region. Furthermore, ‘Dado’ could be used for producing vegetable sprouts due to its seed germination rate and sprout yield, and ‘Sanpo’ seems to be applied to the food industry by utilizing seeds themselves, or by processing them into powder due to its low germination yield and high hard-coated seed rate. - COLLAPSE

- This study investigated the effects of planting time and row cover type on sweetpotato sprout growth under low-temperature conditions. The experiment was conducted in an unheated double-layer greenhouse over two years (2023 and 2024) using three cultivars: ‘Sodammi’, ‘Jinyulmi’ and ‘Hopungmi’. Storage roots were planted in early, middle, and late February, with two row cover treatments: conventional plastic cover (CC) and thermal insulated cover (TC). Results showed that TC increased soil temperature by 1.4℃ and minimum temperature by 2.0℃, which helped reduce sprouting time by 11.3% compared to CC in the cold-sensitive cultivar ‘Sodammi’. ‘Jinyulmi’ exhibited the highest cumulative seedling yield (302.2 seedlings/㎡) under early February planting, while ‘Sodammi’ had the lowest (25.7 seedlings/㎡). TC treatment significantly improved cumulative seedling yield across all cultivars, particularly benefiting ‘Sodammi’ by mitigating low-temperature stress. Additionally, delayed planting in late February led to increased soil temperatures, enhancing sprouting and seedling growth. These findings suggest that adjusting planting time and applying thermal insulated cover can enhance seedling productivity and improve early sprouting. - COLLAPSE

- This study provides basic information on jujube accessions and aims to improve the efficiency of breeding by investigating the stone morphological traits of jujube accessions held by the Jujube Research Institute of the Chungcheongbuk-do Agricultural Research & Extension. Additionally, the study examines germination characteristics by seed storage methods and scarification treatments. The percentage of kernel of the main domestic cultivars, ‘Bokjo’ and ‘Cheonhwang’, were very low at 1% and 0%, respectively. In contrast, the percentage of kernel of five accessions, including ‘Sanjo’, ‘Ilbon’, ‘Jh-1’, ‘Jh-6’, and ‘Jh-11’, were high, around 80%. Germination was not effective even with ground storage, but scarification of the seeds significantly promoted germination. The highest germination rate was observed when seeds underwent complete scarification, although the rates varied depending on the accession. Partial scarification also showed improved germination compared to the untreated seeds. Correlation analysis indicated that accessions with a lower stone morphological index and stone shape closer to a round tended to have higher germination rates and percentage of kernel. Therefore, stone morphological traits alone could be useful for selecting high percentage of kernel accessions and for breeding new cultivars through crossbreeding. - COLLAPSE

- A survey was conducted on general insects, pests, and natural enemy insects occurring on two medicinal plants in Korea, Eleutherococcus senticosus and E. sessiliflorus. The survey was carried out from May 9 to October 10, 2024 in cultivation areas located in Taean-gun and Asan-si, Chungcheongnam-do. The study revealed that among the insects visiting these plants, species belonging to the order Hemiptera exhibited the highest diversity. When pest taxa were classified by functional groups, E. sessiliflorus showed the highest diversity of phytophagous pests (17 species), while E. senticosus had the highest diversity of sap-sucking pests (18 species). In both cultivation areas, pests belonging to the orders Hemiptera and Coleoptera were the most diverse, accounting for 20 species across four orders (51.3%). Regarding natural enemies, the E. sessiliflorus cultivation area had 14 species from five orders, with Hymenoptera (6 species) being the most diverse. Similarly, in the E. senticosus cultivation area, 12 species from three orders were recorded, with Hymenoptera (6 species) being relatively more diverse than other orders. Additionally, the study provides a detailed list of pest species observed and ecological photographs of major pests and natural enemies. - COLLAPSE

- This study was carried out identify the changes in vascular plants in the Muuido area of Jung-gu, Incheon Metropolitan City, and also to use the identified plants as basic data for effective management and biodiversity conservation in the era of climate crisis. The survey was conducted three times and 18 routes by season, from April 2023 to October 2024. A total of 97 families, 328 genera, 496 species, 13 subspecies, 42 varieties, 5 forma, and 556 taxa were identified in the vascular plants in the Muuido area. This is approximately 11.93% of the total 4,660 taxa in the National Species List (vascular plants). Five taxa were identified as endemic species in Muuido, 10 taxa in the Red-list, 78 taxa as floristic target plants, 62 taxa as invasive alien plants, and 7 taxa as ecosystem-disrupting plants. The naturalization rate was 11.15%, and the urbanization index was 14.66%, respectively of Muuido. From 1980 to this study (2023), a total of 798 vascular plant taxa have been recorded on Muuido. As a result of comparing and analyzing the changes in vascular plants before and after the construction of Muui Bridge in 2019, the diversity of vascular plants was found to have increased significantly, but the influx of invasive alien plants also increased sharply. Furthermore, some obligate wetland plants like Utricularia japonica Makino are undergoing local extinction, so management measures such as a fallow year system that can conserve notable plants are urgently needed. - COLLAPSE
