Mulberry fruit is a superior source of polyphenols, especially anthocyanin, and has a long history of use as an edible fruit and traditional medicine. The anthocyanin composition of mulberry fruit from 15 Korean cultivars was analyzed by ultra-performance liquid chromatography diode array detector with quadrupole time of flight/mass spectrometry (UPLC-DAD-QToF/MS) based on a cyanin internal standard. The four glycosides were identified by comparison with authentic standards and published reports. The major anthocyanin was cyanidin 3-O-glucoside (71.7%), followed by cyanidin 3-O-rutinoside (26.6%). The minor components (total of 1.7%) were pelargonidin 3-O-glucoside and pelargonidin 3-O-rutinoside. The total anthocyanin content (mg/100 g, dry weight) of mulberry fruit varied by cultivar and ranged from 471.5±4.0 (Su Hong) to 4,700.2±54.0 (Gwa Sang2). Among the 15 cultivars examined, Gwa Sang2 showed the highest level of cyanidin 3-O-glucoside (3,133.4±32.6), which was 9-fold higher than that of Su Hong (351.5±3.4). In conclusion, anthocyanin profiles, including pelargonidin 3-O-glucoside and pelargonidin 3-O-rutinoside, were reported for the first time from 15 Korean mulberry fruit cultivars. The results will contribute valuable information on pharmaceutical properties, breeding superior mulberry cultivars, and food industries.

To harvest marketable cucumbers, high quality seedlings must be used. Producing seedlings in the greenhouse during the low radiation period decreases marketability due to insufficient light for growth. Supplemental lighting with artificial light of different quality can be used to improve low light conditions and produce high quality seedlings. Therefore, this study was conducted to select the appropriate supplemental light sources on the growth and seedling quality of grafted cucumber seedlings during the low radiation period. Three cultivars of cucumber were used as scions for grafting; ‘NakWonSeongcheongjang’, ‘Sinsedae’, and ‘Goodmorning baekdadagi’. Figleaf gourd (Cucurbita ficifolia) ‘Heukjong’ was used as the rootstock. The seeds were sown on January 26, 2023, and grafted on February 9, 2023. After graft-taking, cucumbers in plug trays were treated with RB light-emitting diodes (LED, red and blue LED, red:blue = 8:2), W LED (white LED, R:G:B = 5:3:2), and HPS (high-pressure sodium lamp), respectively. Non-treatment was used as the control. Supplemental lighting was applied 2 hours before sunrise and 2 hours after sunset for 19 days. The stem diameter and fresh and dry weights of roots did not differ significantly by supplemental light sources. The plant height and hypocotyl length were decreased in W LED. However, the leaf length, leaf width, leaf area, and fresh and dry weights of shoots were the highest in the RB LED. Seedling qualities such as crop growth rate, net assimilation rate, and compactness were also increased in RB LED and W LED. After transplanting, most of the growth was not significant, but early yield of cucumber was higher in LED than non-treatment. In conclusion, using RB LED, W LED for supplemental light source during low radiation period in grafted cucumber seedlings improved growth, seedling quality, and early yield of cucumber.

It is widely known that forage corn is one of the most important crops in the production of silage and green chops during the summer months. In this study, the characteristics and the productivity of Kwangpyeongok, AGR 41, and Nero IT corn cultivars were evaluated in the regions of Jeju and Cheonan, Korea between 2021 and 2022. In each year, different corn cultivars were sown in different parts of the country on April 7 in Jeju and May 3 in Cheonan. The yield of three cultivars, Kwangpyeongok, AGR 41, and Nero IT were measured at the yellow-ripening stage, including the leaves and stems (Stover) and corn grain. Kwangpyeongok stover and total dry matter (DM) yields were slightly higher in Cheonan than in Jeju over the past two years. The quantity of corn cultivated in all cultivated areas was similar. The average yield of AGR 41, corn quantity and total DM were slightly higher in Jeju than in Cheonan. In terms of stover yield, and total dry matter content of the Nero IT cultivar cultivated in Jeju had a slightly higher yield than the cultivar cultivated in Cheonan. Based on this study, all cultivars can show some variations but not too much in terms of growth productivity and distinct characteristics depending on their location. Overall, AGR 41, and Nero IT cultivars in Jeju exhibit slightly higher levels of productivity than the same cultivars in Cheonan.

In this study, the characteristics and taste components of six different oyster mushroom cultivars (Gonji-7ho, Santari, Baekseon, Chunchu, Suhan, and Heuktari) were analyzed and compared. The Heuktari mushroom pileus had the lowest brightness index (32.8) and remained dark (brightness index: 30.5) even after blanching. The moisture content of the mushrooms was approximately 90%. The salinity and sugar contents were highest in Heuktari (5.7% and 7.1%, respectively). Gonji -7ho had the highest contraction rates, with a length contraction rate of 16.4% and thickness contraction rate of 23.9%. The total amino acid content was highest in Heuktari (537.8 mg/100 g), but the glutamine content contributing to umami taste was highest in Santari (59.4 mg/100 g) and the aspartic acid content was highest in Baekseon (33.1 mg/100 g). Among the 5?-nucleotide components, guanosine monophosphate, which enhances umami taste, was highest in Baekseon (0.7 mg/g). Baekseon was also calculated to have the highest umami taste concentration based on amino acid and nucleic acid contents (12.7 g/100 g). The results of this study serve as valuable basic data on the physicochemical characteristics of oyster mushroom cultivars grown in Korea.

This study was conducted to evaluate Korean rice cultivars to search any suitable varieties for the northern region of the Korean Peninsula (North Korea). A total of 92 rice varieties which included 74 bred cultivars from South Korea, 13 collections from North Korea and five local cultivars from China, were involved in the evaluating trials for their performance. Stability at three sites inthe northeastern areas of China, which are located in the northern border areas of North Korea, for three years from 2017 to 2019. The ecologically well-adapted rice varieties were selected at each trial site during the first year and employed again as the materials for the subsequent yield trials. A total of six varieties with relatively better performing and stability were selected through the subsequent trials at three sites for three years: Unkwang, Daejin and Taebaek at Dandong region; Hanseol and Taebong at Longjin region; Taebong and Namweon at Hunchun region, respectively. Dandong is located in the southeast parts of Liaoning, which has similar climatic characteristics to the west coastalregion of North Korea. Longjin is located in the middle-east parts of Jilin, which has also similar climatic characteristics to the northern inland region of North Korea. Hunchun is located in the northeastern parts of Jilin, which has presumably similar climatic characteristics to the northern part of the eastern coastal region of North Korea. Unkwang is characterized by its early maturity, with the heading at the 2nd of August, and reveals a yield potential of 7.11 T/ha with resistance to the blast (BL) and the bacterial leaf blade (BLB) diseases. It is predicted to be suitable for the northern area of the Suyang mountain region and the central inland region of North Korea. Daejin has asemi-early maturity heading around the 6th of August and yields of 6.06 T/ha with resistance to BL, BLB, and stripe virus (SV) diseases. Daejin will be adaptable to the northern area of Suyang mountain region. Taebaek is medium maturing variety of Indica/Japonica type.

In this study, ‘M’, which has high water use efficiency and a large number of fruits, and ‘VL’, which required less quantity to water consumption for producing 200 g of fruit and had a high product weight, will have excellent adaptability in the UAE greenhouse condition.

영남 평야지에서는 추석전 햅쌀 출하를 목적으로 조기재배나 극조기재배가 증가하고 있는 추세이다. 그러나 극조기 벼 수확 이후에 후작물로 적합한 작목이 없어서 휴경을 하는 농가가 많아 적합한 작부체계 개발을 위한 재배법 개발이 필요한 실정이다. 따라서 본 시험은 극조기 벼 수확 후 이모작 작부체계에 적합한 벼 품종 및 재배시기 설정을 위해 수행하였다. 조생종 14개 품종을 4월 7일, 4월 14일, 4월 21일, 4월 28일에 각각 이앙하였을 때, 극조기 벼 이모작을 위한 기준 출수기인 7월 10일 이전에 출수가능한 품종은 백일미, 주남조생, 중모1032, 진옥이었다. 이 품종들의 적산온도로 추정한 적정 이앙시기는 4월 10일에서 4월 20일 사이로, 이 시기에 이앙할 경우 8월 20일 이내에 수확이 가능하여 8월 하순 후작물과의 작기연결성에 유리한 적합 품종으로 판단된다.

본 연구는 절화용 튤립(Tulipa spp.) 4품종을 대상으로 재 식밀도에 따른 생장과 발육 특성을 알아보고 광이용효율을 분 석하여 우리나라에서 튤립 촉성재배시 필요한 기초자료를 얻 고자 실시되었다. 절화용 튤립 ‘Novi Sun’, ‘Timeless’, ‘Il de France’, ‘Dow Jones’ 4품종을 대상으로 구근용 재배 상자 (가로×세로×높이; 60cm×40cm×20cm)에 상자당 48, 70, 96개의 구근을 정식하여 저온처리 이후 비닐하우스로 운반되 었다. 그 결과, ‘Novi Sun’과 ‘Timeless’는 온실 이식 이후 35 일 만에 수확되었으며 ‘Il de France’와 ‘Dow Jones’는 그보 다 빠른 30일 만에 수확되었다. 모든 품종에서 재식밀도가 증 가할수록 생체중, 줄기 직경, 엽면적이 감소하였다. 정상개화 율은 96bulbs/box 처리에서 특히‘Novi Sun’ 32.7%과 ‘Timeless’ 4.7%로 감소하였으며 이 두 품종에서 줄기와 꽃의 건물중이 크게 감소하는 것으로 나타났다. 광이용 효율과 밀접 한 지표인 엽면적지수는 재식밀도가 높아질수록 증가하였다. 광합성 효율은 ‘Novi Sun’과 ‘Timeless’의 경우 저광도에서 재식밀도에 따라 큰 차이가 없는 것으로 나타났다. 엽면적 감 소와 형태적인 변화가 작은 ‘Il de France’과 ‘Dow Jones’에 서 광합성 효율이 크게 변화하였다. 재식밀도에 따라 다양한 생육 반응은 유사한 경향은 있으나 품종에 따라 광합성 효율과 동화산물의 분배가 크게 달라지는 것으로 나타났다. 튤립 촉성 재배 시 정상적인 꽃의 발달과 생육 확보를 위해서는 충분한 재식 간격을 확보할 수 있는 재식밀도로 정식해야 한다.

The physiological characteristics, growth, and yield of each regional rice variety (‘Odaebyeo’, ‘Saechucheong’, ‘Ilmibyeo’) were investigated depending on the impact of changes in temperature and CO2 concentration. Experiments were conducted with a control group, which reflected atmospheric CO2 concentration and temperature, and treatment groups, in which the CO2 concentration and temperature were increased by 250 ppm and 2.0℃ from those in the control group. The results showed that the increase in CO2 concentration and temperature reduced the growth and yield of the rice ‘Odaebyeo’, but did not substantially change the productivity of the ‘Saechucheong’ and ‘Ilmibyeo’. The increase in CO2 concentration and temperature increased stomatal conductance and rate of transpiration of the ‘Odaebyeo’ variety, thereby decreasing its water use efficiency (WUE). In contrast, the increase in CO2 concentration and temperature increased the photosynthetic rate and WUE of the ‘Saechucheong’ and ‘Ilmibyeo’ varieties. The gradual change in climate is considered to directly affect growth and development of rice and diversely affect the productivity of each variety. Therefore, it is necessary to implement technological development, select regionally optimal rice varieties, develop new rice varieties, as well as conduct long-term monitoring of each rice variety for climate adaptation to counter global warming.

This study compares the quality characteristics of Jeung-pyun prepared by supplementing with rice mash of various cultivars. Results showed high contents of crude protein and crude ash in Saeilmi. The highest and lowest amylose contents were obtained in Goami4 and Baekjinju, respectively. Saeilmi had the highest water absorption index (WAI) of rice flour, whereas the highest water-soluble index (WSI) was obtained in Baekokchal. Maximum viscosity, minimum viscosity, and breakdown were high in Baekjinju, and high cooling viscosity and setback levels were determined in Goami4. The sugar content, total free sugar, and pH of the rice mash were highest in Baekjinju. The highest volume of Jeung-pyun was obtained with Saeilmi supplementation, whereas the specific volume was highest in Baekokchal. Evaluation of L, a, and b color values of Jeung-pyun revealed the maximum L value in Saeilmi, a value in Goami4, and b value in Baekjinju. The physical properties of Jeung-pyun were lower in all supplemented groups compared to the control group for hardness, adhesiveness, and chewiness. The lowest chewiness was obtained in Baekokchal-supplemented Jeung-pyun. We conclude that supplementation with different varieties of rice affects the quality characteristics of Jeung-pyun, which are important factors for manufacturing processed foods.

This study aimed to investigate the biological activities, including polyphenolic content, flavonoid content, and antioxidant activities, of various cultivars of Korean perilla leaves. The results indicated that among nine cultivars (Namcheon dlggae, Saedora, Nulbora, Donggel 1, Donggell 2, Soim, Sangyeop, Somirang, and Saebom) of perilla leaves, the total polyphenolic content (gallic acid equivalent mg/g, GAE) was the highest in “Nulbora,” while it was lowest in Namcheon dlggae. Moreover, flavonoid content in the extracts of nine cultivars leaves was in the range of 132.93~268.50 mg catechin equivalent/g sample. The antioxidant effects of the perilla leaves were determined using two different in vitro bioassays measuring DPPH and ABTS radical-scavenging activities. The results revealed that antioxidant activity was also higher in “Nulbora” compared with other cultivars. Xanthin-oxidase-inhibition activity ranged from 65.65% to 80.58%, with “Nulbora” exhibiting the highest activity, although the difference with other cultivars was not significant. “Nulbora” extracts reduced the expression of pro-inflammatory genes and several cytokines, including IL-6 activation induced by LPS in macrophages in the range of 100–50 μg/mL. These results suggest that extracts from perilla leaves can be used as bioactive and functional materials that could be important in industrial applications in the future.

In vitro digestibility and protein digestibility corrected amino acid scores (PDCAAS) were investigated to verify the availability of protein in various Rhizopus oligosporus fermented products of domestic soybean (Glycine max L.) cultivars. Danbaegkong (DBK), Daepung (DP), Daewonkong (DWK), Saedanbaek (SDB), Seonyu (SY), and Cheongja4ho (CJ4) were used as raw samples, which were fermented using commercially available Rhizopus oligosporus for 48 h. All cultivars showed increased crude protein content after fermentation. The crude protein content of DBK and SDB was significantly higher than that of the other samples (55.12% in DBK and 54.22% in SDB) (p<0.001). CJ4 had the highest alanine content of 28.88 mg/g (p<0.001), and no significant difference in cysteine content was detected among the cultivars. In most of the fermented samples, the in vitro digestibility was 0.9 or higher, indicating high protein in the fermented samples. However, it is considered that restrictions on digestion are low. In DWK, the amino acid content and PDCAAS, which together indicate protein quality, were 0.917 and 0.855, respectively, confirming that it was the best cultivar to provide the raw material for fermentation. In conclusion Rhizopus oligosporus fermented soybean products can be considered a prospective source of protein with high utility value.

밀은 세계 3대 주요 작물이지만 우리나라는 대부분 수입에 의존하고 있으며, 자급률이 1%도 도달하지 못한 실정이다. 국내 밀 품종은 40여 종 이상으로 지속적으로 개발되고 있으며, 품종마다 용도와 농업적 특성이 달라 목표 형질에 맞는 적절한 품종을 선택하여 재배하는 것이 중요하다. 품종을 정확하고 빠르게 판별하기 위해선 분자 마커 기술이 필요하다. 분자 마커는 생육 환경과 시기에 영향을 받지 않고 다양한 품종을 신속하고 정확하게 구분할 수 있어 유전적 변이성, 농업 형질 등을 분석하기에 유용하다. 본 연구는 기존에 보고된 국내 밀 32품종에 대한 SCAR (Sequence Characterized Amplified Region) 판별 마커를 재검정하여 재현성이 높은 마커를 선별하였으며, 기존에 검정되지 않은 국내 밀 9품종에 추가 적용하여 비교분석하였다. 15개의 마커 세트 중 6개의 마커가 재현성과 정확도가 높은 것으로 확인되었고, 최종적으로 국내 41품종 중 4, 7, 8, 10, 11, 12번 마커를 이용하여 다홍, 금강, 밀성, 조은, 수강, 한백, 조광, 영광을 판별할 수 있었다. 또한, 4번 마커를 통한 증폭산물의 염기서열 분석을 통해 SNP (Single Nucleotide Polymorphism)를 발굴하여 ‘올밀’에 대한 새로운 품종 판별 마커인 SdHRM1과 SdHRM2를 개발하여 HRM (High Resolution Melts) 분석을 시행하여 육안으로 판단하기 어려운 SNP를 정확하게 판별할 수 있었다. 품종간의 SNP를 활용한 품종 마커 기술은 다양한 농업형질에 적용할 수 있으며, 분자 육종 프로그램에 실질적인 도움이 되는데 큰 기여를 할 것으로 사료된다.

Kale (Brassica oleracea var. acephala) is one of the most frequently consumed leafy vegetables globally, as it contains numerous nutrients; essential amino acids, phenolics, vitamins, and minerals, and is particularly rich in glucosinolates. However, the differences in the biosynthesis of glucosinolates and related gene expression among kale cultivars has been poorly reported. In this study, we investigated glucosinolates profile and content in three different kale cultivars, including green (‘Man-Choo’ and ‘Mat-Jjang’) and red kale (‘Red-Curled’) cultivars grown in a vertical farm, using transcriptomic and metabolomic analyses. The growth and development of the green kale cultivars were higher than those of the red kale cultivar at 6 weeks after cultivation. High-performance liquid chromatography (HPLC) analysis revealed five glucosinolates in the ‘Man-Choo’ cultivar, and four glucosinolates in the ‘Mat-Jjang’ and ‘Red-Curled’ cultivars. Glucobrassicin was the most predominant glucosinolate followed by gluconastrutiin in all the cultivars. In contrast, other glucosinolates were highly dependent to the genotypes. The highest total glucosinolates was found in the ‘Red-Curled’ cultivar, which followed by ‘Man-Choo’ and ‘Mat-Jjang’. Based on transcriptome analysis, eight genes were involved in glucosinolate biosynthesis. The overall results suggest that the glucosinolate content and accumulation patterns differ according to the kale cultivar and differential expression of glucosinolate biosynthetic genes.
