Recently in Korea, soybean harvesting has been delayed due to rainfall during the harvesting season, resulting in a reduction in yield and seed quality. This study was conducted to analyze the changes in yield and seed quality during delayed harvest with rainfall treatment using different harvesting methods, including field harvesting and polyethylene film covering after cutting fully-matured soybean plants (PE covering after cutting), with two major Korean soybean cultivars (Glycine max L), Pungsannamulkong and Daewonkong. The shattering rate of Pungsannamulkong, which is higher than that of Daewonkong, increased up to 41.8% when the harvest was delayed for 40 days without rainfall treatment by harvesting with PE covering after cutting. The weight of 100 seeds tended to decrease slightly as harvesting was delayed. When Daewonkong was harvested using the PE covering after cutting method with rainfall treatment, the yield decreased to the lowest level with a 0.8 kg ha^-1 daily reduction rate. Pungsannamulkong showed the lowest yield when harvested using PE covering after cutting without rainfall treatment with a 3.4 kg ha^-1 daily reduction rate. The infected seed rate increased according to the harvest delay in both cultivars, and significant differences were observed according to rainfall treatment and harvesting method. The germination rate was maintained above 95% even after 40 days of delayed harvest if there was no rainfall treatment. However, with rainfall treatment, the germination rate was significantly lowered as harvesting time was delayed. In the field harvesting with rainfall treatment, the germination rate decreased to 77.2% for Daewonkong and 76.5% for Pungsannamulkong after 40 days of harvest delay. For the 100-seed weight, effects of individual treatments and interactions between treatments were not observed. In contrast, the effect of interactions between treatments on the shattering rate was significant in both cultivars, indicating that the shattering rate had the greatest impact on the yield changes during delayed harvest.

건전한 어린모 육묘를 위한 유묘 초기의 무기양분 공급 필요성을 평가하기 위하여 발아 및 유묘 생육초기의 양분 결핍이 유묘 생육에 미치는 영향을 다산벼를 이용하여 조사하였다. 양분 결핍처리는 Yoshida액을 사용하여 질소, 인산, 칼륨, 칼슘, 철 등의 단일성분 결핍처리와 증류수를 이용한 모든 양분 결핍처리를 실시하였다. 양분 결핍처리를 발아시 또는 발아 5일후부터 5-10일동안 처리하여 유묘의 주요 생육형질을 조사 분석하였다. 양분 결핍에 의해 유묘의 초장, 생체중, 지상부생체중, 근장, 근생체중 등이 현저히 감소하였다. 유묘생육 저해정도는 질소 결핍구, 철분 결핍구, 모든 양분 결핍구에서 더욱 컸다. 유묘의 생육은 발아개시기보다는 유묘초기의 양분 결핍에 의해 더 감소되었다. 이상의 결과는 주요 무기 양분이 발아과정에는 미미한 영향을 주나, 유묘의 생육에는 크게 영향을 미치며, 특히 질소와 철분의 영향이 큰 것을 의미한다. 그러므로 건묘육성을 위해서는 유묘종자의 배유양분이 소진되기 이전의 유묘초기에 질소 및 철분 등 무기양분의 공급이 필요한 것으로 판단된다. Infant seedling transplanting outweighs direct seeding in stability, productivity, and product quality of rice cultivation though it requires intensive management in seedling nursery. This study was conducted to identify key mineral nutrients for the production of quality infant seedlings by analyzing the effects of mineral nutrients deficiency on early seedling growth. Deficiency of N, P, K, Ca, Fe, or all nutrients was induced by using Yoshida`s nutrient solution for up to 10 days from germination or 5 days after germination in Dasanbyeo. Seedling height and fresh weight, shoot fresh weight, root number, root length, and root fresh weight were decreased by deficiency of the nutrients, but most severely by N or Fe deficiency. This result demonstrates the relatively greater importance of N and Fe than other nutrients in early seedling growth. Seed germination was little affected by any nutrient. The results indicate that additional supply of nutrients should be considered based on the nutrients levels of nursery soil for quality seedling production.

김영진,오영진,조상균,김정곤,박명렬,윤성중,Kim, Young-Jin,Oh, Young-Jin,Cho, Sang-Kyun,Kim, Jung-Gon,Park, Myoung-Ryoul,Yun, Song-Joong 한국작물학회 2006 Korean journal of crop science Vol.51 No.suppl1

우수한 기능성을 가진 나물콩을 생산하기 위하여 isoflavone함량이 높은 품종을 선발하고, 재배적 방법에 의한 원료콩 종실의 isoflavone함량의 증진 가능성을 조사하는 한편, 콩나물의 재배 일수에 따른 콩나물 부위별 isoflavone 함량의 경시적 변화 양상을 조사한 결과를 요약하면 다음과 같다. 1. 공시한 나물콩 21품종의 종실에 함유된 daidzein과 genistein의 총 함량은 $756{\sim}1,682{\mu}g/g$으로 품종간 차이가 컸으며, 특히 익산 13호$(1,682{\mu}g/g)$ 및 남원재래$(1,500{\mu}g/g)$에서 함량이 높았다. 2. Daidzein 함량은 익산 13호$(924{\mu}g/g)$ 및 IT 160996 $(828{\mu}g/g)$에서 높았으며, genistein 함량은 익산 13호$(758{\mu}g/g)$ 및 남원재래$(756{\mu}g/g)$에서 높았다. 3. 풍산나물콩의 영양생장기에 식물생장조절제인 안티폴$(2,472{\mu}g/g)$과 후라스타$(2,052{\mu}g/g)$를 처리하였을 때 daidzein과 genistein의 총 함량이 대조군$(1,800{\mu}g/g)$에 비하여 각각 37%와 14% 증가하였다. 4. 은하콩의 콩나물 재배일수 경과에 따른 isoflavone 함량은 자엽의 경우 변화가 미미하였으나, 배축의 경우 daidzein이 치상 후 3일까지 증가하다 4일째부터 급격히 감소하는 경향을 나타냈으며, 배축의 genistein함량은 콩나물 재배기간이 경과할수록 감소하였다. 5. 풍산나물콩의 콩나물 재배일수 경과에 따른 isoflavone 함량은 은하콩과 달리 자엽의 경우에는 변화가 미미하였으나, 배축의 경우 daidzein이 치상 후 1일에 $5,154{\mu}g/g$까지 증가했으나 재배일수가 경과함에 따라 급격히 감소하는 경향을 나타냈으며, 배축의 genistein함량은 큰 변동을 보이지 않았다. 6. 콩나물재배 6일째부터 발생한 잔뿌리에는 isoflavone 함량이 $4,416{\mu}g/g{\sim}5,232{\mu}g/g$으로 매우 높았다. 7. 고기능성 나물용 콩을 육성하기 위해서는 원료콩 종실의 isoflavone함량이 높고, 콩나물이 식용으로 이용되는 시기까지 isoflavone함량이 크게 감소하지 않는 특성을 가진 품종의 육성이 필요할 것으로 생각된다. Biofuctionality of soybean seeds and soy-bean products have been fortified by the uncovering of the multifuctional beneficial effects of isoflavones. As one way to fully utilize beneficial effects of isoflavones in soybean sprout is through the enhancement of isoflavone contents in soybean seeds, genetic selection for higher isoflavone and cultivational measures to increase isoflavone content in soybean seeds were attempted. Isoflavones (daidzein, gemstein) contents in soybean seeds and soybean sprouts were determined by high performance liquid chromatography. Total isoflavone contents in soybean seeds ranged from 756 to $1,682{\mu}g/g$ and Iksan #13 $(1,682{\mu}g/g)$ showed highest content among the 21 germplasms analyzed. Onetime treatment of soybean plants with Antipol or Piaster at the $V_4$ stage yielded seeds with higher isoflavones as $2,472{\mu}g/g\;or\;2,052{\mu}g/g$, respectively, which were higher by 37% and 14% than that of seeds in the control plants, respectively. In Eunhakong, Isoflavone contents of soybean sprout changed during sprouting. Daidzein content in hypocotyl increased to maximum on the third day of cultivation and decreased there-after, whereas the content changed little in cotyledon. In sprouts of Pungsannamulkong, daidzein content in hypocotyl showed a maximum level on the first day and decreased gradually thereafter but, the content changed little in cotyledon. Total isoflavone contents in lateral roots which developed on the 6th day after sprouting ranged from 4,416 to $5,232{\mu}g/g$ DW.

Consumer demand for Triticale cultivars as a winter forage crop in Korea has been increasing because of its ability for high andstable yield. However, more than 10 years are required to develop new varieties with conventional breeding programs. A speed breedingsystem using long-day photoperiodic treatment has recently been suggested and applied in wheat and barley, but not in the triticale breedingprogram in Korea. To evaluate the availability of the established speed breeding system for triticale breeding programs in Korea, we usednine domestic triticale cultivars to investigate their growth characteristics under a 22 h photoperiod. The average days to heading (DTH) ofthe nine cultivars was 38 days, and Gwangyoung and Minpung showed the most delayed DTH at 42 days. Therefore, all nine triticale cultivarswere able to shorten the growth duration under the tested photoperiod condition. One productive tiller and more than 10 seeds were obtainedfrom each cultivar. The germination percentage was over 82% when the spikes were harvested 20 days after heading, dried, and chilled fora week to break dormancy. These results suggest that in Korea, the rapid generation advancement system with simple long-day photoperiodictreatment can be applied to triticale breeding programs to reduce the breeding time.

본 연구에서는 국내산 트리티케일 3품종(신영, 조성, 신조성)의 이화학적 특성을 조사하고 이를 국내 품종의 밀(백강, 새금강) 및 호밀(씨드그린)과 비교하였다. 트리티케일은 7.77-9.69%의 단백질을 함유하여 밀과 호밀의 단백질 함량보다 다소 낮았지만, 전분함량이 높아(81.57-85.25%) 에너지원 또는 전분 기반 소재에 활용도가 높을 것으로 생각된다. 신영과 조성의 탄산나트륨 보유능은 각각 72.5와 82.0%로 이는 새금강과 백강과 비슷한 수준이었으며 신조성은 97.6%로 트리티케일 중 제분에 의한 전분 손상이 가장 많이 발생한 것을 알 수 있다. 50% 자당 보유능에서는 조성과 신조성은 신영보다 펜토산에 의한 수화 능력이 높았지만, 트리티케일의 젖산 보유능은 밀과 호밀보다 현저하게 낮아 글루텐 형성에는 취약함을 알 수 있다. 이는 wet gluten의 결과에서 트리티케일의 글루텐형성능이 밀가루의 30-50% 수준이었던 것과도 상응하며 트리티케일 중 신조성이 다른 품종보다 높은 GPI와 wet gluten을 나타내 양적 및 질적으로 가공에 유리할 것으로 생각된다. 조성과 신영은 peak viscosity가 200cp 미만으로 빵용 밀인 백강보다 낮은 반면, 신조성은 백강과 새금강의 중간 수준의 점도를 나타내었고 최종적으로 조성과 신영은 저점도의 페이스트 특성을 보였지만 신조성의 경우 다른 두 품종보다 5배 높은 점도를 가지고 있었다. 트리티케일은 낮은 호화 피크와 호화 엔탈피 값이 관측되었다. α-amylase에 의한 전분 가수분해 특성에서 트리티케일은 밀과 호밀보다 초기 20분 동안 가수분해가 더 많이 진행되었으며 120분이 경과하였을 때 밀과 호밀은 38.2-42.2% 수준인 반면 트리티케일은 47% 이상으로 가수분해 정도가 현저히 높았다. 국내산 트리티케일 품종과 특성에 대한 기초연구와 이를 기반으로 한 가공 연구를 다각적으로 수행한다면 국내 식량작물로부터 새로운 식품소재 창출과 더불어 식량안보문제 해결에도 기여할 수 있을 것이라 생각된다. This study investigated the physicochemical properties of domestic triticale flour and compared it with domestic wheat and rye flour. The triticale flour had a low protein content (7.7-9.7%) but a high total starch and amylose content compared to that of the wheat and rye flour. Shinjoseong showed the highest solvent retention capacity for four solutions (water, Na₂CO₃, lactic acid, and sucrose) among the triticale flour. The wet gluten content of triticale ranged from 13.6- 20.4%, which is lower than that of wheat flour (35.7-39.0%). Joseong showed low viscosity behavior in rapid visco analyzer (RVA), and Shinjoseong showed ranges between Baekkang and Saekeumkang flour. The differential scanning calorimetry (DSC) results showed that Shinyoung had a higher gelatinization temperature and enthalpy compared to that of the other triticale flours. All the triticale flour was hydrolyzed over 50% by α-amylase solution for 120 min, which is higher than wheat and rye flour. This study is expected to provide basic information regarding domestic triticale for the food industry and expand its utility by identifying the physicochemical properties.

This study aimed to assess the disease incidence and distribution of toxigenic in Korean triticale. The patho- gen of triticale that cause Fusarium head blight were isolated from five different triticale cultivars that culti- vated in Suwon Korea at 2021 year. The 72 candidate were classified as a Fusarium asiaticum by morphology analysis and by ITS1, TEF-1α gene sequence analysis. And the results of pathogenicity with 72 isolates on seed- ling triticale, 71 isolates were showed disease symptom. Also, seven out of 71 Fusarium isolates were inoculat- ed on the wheat, to test the pathogenicity on the different host. The results showed more low pathogenicity on the wheat than triticale. The results of analysis of toxin type with 72 isolates, 64.6% isolates were produced nivalenol type toxin and other 4.6% and 30.8% isolates were produce 3-acetyldeoxynivalenol and 15-acetyl- deoxynivalenol, respectively. To select fungicide for control, the 72 Fusarium isolates were cultivated on the media that containing four kinds fungicide. The captan, hexaconazole, and difenoconazole·propiconazole treated Fusarium isolates were not showed resistance response against each fungicide. However, six isolates out of 72 isolates, showed resistance response to fludioxonil. This study is first report that F. asiaticum causes Fusarium head blight disease of triticale in Korea.
