- In this study, the anti-obesity effect of Geranium wilfordii Maxim. extract was studied using 3T3-L1 cells. Geranium wilfordii Maxim. was extracted with water (NG-GT-T1L), 10% ethanol (NG-GT-T2L), 30% ethanol (NG-GT-T3L), 50% ethanol (NG-GT-T4L), 70% ethanol (NG-GT-T5L), and the effects on cell viability, lipid accumulation, triglyceride content, and protein expression in 3T3-L1 cells were confirmed. It was confirmed that NG-GT-T3L extract was superior to other extract conditions in reducing lipid accumulation and triglyceride content in the concentration range that did not show cytotoxicity. In addition, it was confirmed to suppress adipogenesis and lipogenesis by reducing the expression of peroxisome proliferator-activated receptor-gamma (PPARγ) and CCAAT/enhancer binding protein-α(C/EBPα) proteins that regulate adipogenesis, decreasing the expression of fatty acid synthetase (FAS) and stearoyl CoA desaturase-1 (SCD-1) proteins that regulate lipogenesis, and increasing the expression of AMP-activated protein kinase (AMPK) protein. From these research results, Geranium wilfordii Maxim. NG-GT-T3L extract is believed to have anti-obesity reduction effects through suppressing lipid accumulation and triglyceride accumulation and regulating adipogenesis and lipogenesis-related proteins. - COLLAPSE

- To speed up the extract of endoparasitic nematodes from roots, four extraction methods with or without root-grinding were compared; 1) immersion, 2) immersion + Air, 3) Oostenbrink dish, and 4) Mistifier. The experiments were conducted for nine days by using perilla roots infested with Pratylenchus vulnus. Root-lesion nematodes continuously extracted from perilla roots during the experiments and as much as 3-10% in 9th days. The total number of nematodes extracted from 2 g of perilla root in nine days were varied among methods (379-1,824 nematodes); the most nematodes were extracted by root grinding + immersion + air (1,824) and the root-grinding + mistifier method (1,349) (p = 0.05). In the first two days of extraction, root-grinding + mistifier extracted the most nematodes (725 nematodes), followed by root-grinding + immersion + Air (555 nematodes), and root-grinding + Oostenbrink dish (421 nematodes). Root-grinding effected as much as 16-108% more nematodes extraction when compared to without root-grinding (p = 0.01). - COLLAPSE

- ‘Jinha’ is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2019. The ‘Jinha’ cultivar originates from a 2011 cross between ‘Albion’ 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. 11’ after examining its characteristics and productivity during summer cultivation between 2012 and 2016. After regional adaptability tests, ‘Jinha’ was selected from ‘Saebong No. 11’ as an elite cultivar. The general characteristics of ‘Jinha’ include intermediate, elliptic leaves, and medium growth. The fruits are conical and of a red color. The plant height of ‘Jinha’ is simiar to that of the control variety, ‘Flamenco’, but it has a lot of number of leaves. The cluster length of ‘Jinha’ was 35.5 ㎝, 10.8 ㎝ longer than 24.7 ㎝ of the control variety. The number of flower clusters of ‘Jinha’ appeared 14.4, which was 4.1 more than that of ‘Flamenco’. The average fruit weight of ‘Jinha’ was 10.1 g, which was 0.8 g heavier than that of ‘Flamenco’. The soluble solid content of ‘Jinha’ was 10.2 ˚Brix, which was 2.0 ˚Brix higher than that of ‘Flamenco’. The marketable yield of ‘Jinha’ was 25,931 ㎏·㏊−1, 440% more than that of ‘Flamenco’ with 5,900 ㎏·㏊−1. Therefore, the new cultivar of ever-bearing strawberry ‘Jinha’ is expected to be very popular in the export or bakery market because it is high soluble solid content and good shape. - COLLAPSE

- This study was conducted to find the flowering and growth characteristics according to the different altitudes (plains and mid-mountain regions) and cultivation methods (field and plastic houses cultivation) of Elsholtzia splendens. Experimental regions located at 12 meters and 500 meters above sea level were selected for the plains and the mid-mountain, respectively, and the same method was applied for cultivation management by different altitudes and cultivation methods. In the mid-mountain region, flower bud emergence (2-3 days), flowering (9 days), and full bloom (6-7 days) stages of Elsholtzia splendens were earlier than in the plains, and field cultivation was earlier than plastic house cultivation. The plant height, the main stem diameter, and the number of branches tended to increase gradually after an initial rapid growth at 59 to 69 days after planting date. The days of duration of sunshine (less than 8 hours) from the rainy season (June 20) to the period when vegetative growth increases gradually (59 to 69 days after planting) was 22 to 29 days and 26 to 35 days in the plains and the mid-mountain regions respectively, and this period was estimated time of transition from vegetative growth to reproductive growth. The spikes growth of Elsholtzia splendens by cultivation altitudes was higher in the mid-mountain region than in the plains, and there were no statistically significant differences in growth characteristics except for the main stem diameter, the number of branches, and the dry matter. Also, the amount of flowering and growth was higher in the plastic house cultivation compared to the field cultivation. As a result, some differences in flowering amount were observed when cultivating Elsholtzia splendens for landscaping purposes, but it was considered possible to cultivate in both plains and mid-mountain regions. This study therefore provides ecological information for understanding the relationship between weather characteristics and growth of Elsholtzia splendens. - COLLAPSE

- This study was undertaken to elucidate the effects of virus and viroid infections on the growth of trees and the attributes of fruit quality in ‘Hongro’ apples. Trials were initiated using virus-infected, viroid-infected, combined virus/viroid-infected, and uninfected apple trees in an experimental apple orchard at the National Institute of Horticultural and Herbal Science in 2019. The growth of each tree was measured annually and compared between virus-free and virus/viroid-infected trees. Fruits were harvested from all apple trees, and selected attributes of fruit quality, including yield, weight, firmness, titratable acidity, and anthocyanin content, were determined in September 2021-2022. The results revealed significant differences among virus-free trees and those infected with either virus, viroid, or a combination of virus and viroid. Infection with viral and viroid diseases led to reductions in tree height (14.0%), trunk area (23.1%), fruit yield (65.0%), fruit weight (34.4%), and anthocyanin content (39.8%), while increasing fruit firmness (33.2%) and titratable acidity (39.8%), respectively. We anticipate that our research findings will also be beneficial for apple virus and viroid disease control, as well as apple cultivation management. - COLLAPSE

- Naked oat is particularly vulnerable to cold weather among cereal crops, and frequent lodging due to their long culm length. Also it is difficult to cultivate in double cropping system with rice because of late maturity in Korea. In this study, we charaterized 71 naked oat germplasms including two control varieties with agronomic traits, to select superior resources and use them for the improvement of exsiting varieties. The maturity date was May 26th for ‘Joyang’ and June 1st for ‘Daeyang’, and there were 5 resources including IT302003, which was earlier than Daeyang. In the case of culm length, the distribution ranged from 62 to 124 ㎝, and there were 13 resources, including IT209241, that were shorter than ‘Joyang’ (84 ㎝) and ‘Daeyang’ (83 ㎝). In correlation analysis of agronomic traits, the highest positive correlation (r=0.89) was observed between days to heading and days to maturity. In addition, culm length and spike length (r=0.72) and days to heading (r=0.50) showed a positive correlation. However, Barley yellow dwarf virus(BYDV) and grain yield (r=-0.30), lodging tolerance and liter weight (r=-0.37) showed a negative correlation. Cluster analysis, resources with similar traits such as liter weight, husk ratio, days to heading, and days to maturing were subclassified. Through this analysis, 6 resources, including IT302002 (X345-1-B4-20-1), which had short culm length, early maturity, and cold tolerance compared to ‘Joyang’ and ‘Daeyang’, were selected. Among the selected excellent resources, the avenanthramide content of the four resources was IT302002 (325.18 ㎍/g), K000010 (557.3㎍/g), K253299 (447.33 ㎍/g), and K253301 (440.49 ㎍/g), respectively, which was higher than ‘Daeyang’ (301.97 ㎍/g). These excellent resources will be used as breeding materials for the development of new varieties in the future. - COLLAPSE

- Cymbidium (C.) spp. 'Wedding Day' was developed by the National Institute of Horticultural and Herbal Science, Rural Development Administration in 2021. This cultivar was derived from the artificial cross between C. ‘Boksam Holiday’ and C. ‘Persicolor’ in 2008. After the crossing, 112 seedlings were obtained through in vitro germination and transferred to the green house. Based on their vegetative and flowering characteristics, two lines were selected through the first selection. To confirm the stability and uniformity of the two lines, the first and second trials were conducted from 2017 to 2021. As a result, the final line with the code ‘C0844-29’ was selected as ‘Wongyuo F1-78’. After evaluating consumer preference, the line was named as ‘Wedding Day’. This hybrid is medium sized cultivar with long vase life of cut flowers and more than 11 white flowers per stalk. It has 63.2 ㎝ of erect stalks which are suitable for cut flower. The leaves are 65.8 ㎝ long and located lower than the flowers, providing appropriate shape for viewing the flowers. It starts flowering from late January. It has sufficient proliferation ability to enable mass proliferation for commercial use (Registration No. 9523). - COLLAPSE

- Hops enhance beer flavor and bitterness, acting as a preservative. In recent years, the booming trend of craft beer has prompted the introduction of foreign hop varieties for cultivation and production in South Korea. This study focuses on developing efficient in vitro culture condition of the hop (Humulus lupulus L.) variety ‘Cascade’ for treatments of plant growth regulators, i.e. IAA and Cytokinin. Using Auxin IAA and Cytokinin 2iP, Zeatin, BAP, and TDZ on MS medium as plant growth regulators, the experiment involved removing three nodes from the shoot apex. In vitro hop culture showed the highest shoot proliferation rate when only IAA was added, with approximately 21% higher compared to the combination with Cytokinin. Notably, IAA 0.1 ㎎/L + BAP 1 ㎎/L resulted in a superior shoot proliferation rate of around 91%. IAA 0.1 ㎎/L + BAP 1 ㎎/L was advantageous for shoot elongation. Callus induction occurred with TDZ, while control or IAA-only conditions exhibited shoot and root growth. Cytokinin addition led to callus formation and increased weight. Assessing survival and soil adaptation during in vitro hop seedling acclimatization involved maintaining near 100% humidity initially, gradually reducing it over three weeks. When transferred outdoors, 9 out of 10 seedlings acclimated successfully, confirming a 90% acclimatization rate. - COLLAPSE
