윤승길 안성산업대학교 2000 論文集 Vol.32 No.-

질소 시비가 whole crop silage용 도입 트리티케일의 수량 및 사료가치에 미치는 영향을 검토하여 양질 다수확을 할 수 있는 적정 시비량을 구명하고자 실험한 결과를 요약하면 다음과 같다. 1. 질소 시비량에 따른 초장은 처리간 유의성이 인정되지 않았다. 2. 청예, 건물수량 및 건물율은 질소 시비량의 증가에 의해 유의하게 md가되었고, 품종간 경향도 일정하였다. 3. 조단백질, 조지방 조회분, NFE 함량은 질소 시비량의 증가에 따라 유의하게 증가되었으나 조섬유 함량은 감소되어 반대의 경향을 보였다. 4. TDN 함량은 질소 시비량의 증가에 따라 유의하게 증가되었고, TDN 수량도 유의하게 증가되었는데 10a당 20㎏ 시비구가 12㎏ 시비구에 비해 평균 100㎏ 이상 높았다. Effects of nitrogen fertilization on the forage yield and feed value of the introduced triticale plants for whole crop silage were studied to determine the nitrogen dosage which could fulfill both of high yield and quality. 1. The heights of triticale plants were not effected by the nitrogen applicstion rates statistically. 2. The increase of nitrogen application rates increased the fresh and dry weight and dry/fresh weight ratio of triticale plants. All varieties showed the same trend. 3. Contents of crude protein, lipid, and ash and NEF in triticale plants were increased with increase of nitrogen fertilization rates. The contents of crude cellulose showed the reverse trend. 4. TDN contents increased with increase of nitrogen rates. TDN yield at 20㎏ N/10a application was 100㎏/ha higher then those at 12㎏ N/10a application.

尹承吉 안성산업대학교 1996 論文集 Vol.28 No.-

본 시험은 農業形質에 의한 秋播性 Triticale의 品種을 分類하기 위하여 대부분 도입 品種인 PRESTO외 21品種을 공시하여 安城産業大學校 田作圃場에서 실시하였는데 그 결과를 要約하면 다음과 같다. 1. 草長은 팔당호밀이 Triticale보다 모든 조사 시기에서 길었으나 出穗期 이후 木質化가 빠르므로 木質化가 느리면서 草長이 긴 Triticale은 PRAG46/3, PIKA, LAIDAGUS등 이었다. 2. 生體重과 乾物重은 팔당호밀이 1차 조사에서 가장 우수했지만 2차, 3차, 4차에서는 Triticale인 신기호밀, PRAG46/3, PRESTO, PABLO, PREGO 등이 우수한 성적을 보였다. 3. 본 시험에 공시한 모든 Triticale은 대조구인 팔당호밀보다 出穗期가 10일 이상 늦었지만 기존 品種인 신기호밀보다 빠른 品種은 PRESTO, MAGISTRAL이었다. 4. 收量構成要素는 대부분의 Triticale品種들이 팔당호밀보다는 높았는데 신기호밀보다 양호한 品種은 LASKO, CLERCAL이었다. The purpose of the experiments was to select the agronomically favorable autumn triticale varieties based on the plant growth characteristics. The experiments were conducted in upland fields of Ansong National University using 20autumn triticale varieties, all of them were induced varieties except one, Shinkihomil, as a control, also, one domestic rye variety, Paldanghomil, was used for the comparison with triticale varieties. The obtained were as follows: 1. Paldanghomil showed the highest plant height through all growth periods, but was repidly lignified after heading stage. While PRAG46/3, PIKA and LAIDAGUS showed hight plant height with slow lignification. 2. In the early growth stage, April 24, Paldanghomil showed the heaviest fresh and dry weight, but in later growth stages Shinkihomil. PRAG46/3, PRESTO, PABLO and PREGO showed heavier fresh and dry weight compared with Paldanghomil. 3. The heading dates of all triticale varieties were delayed more than 10 days compared with Paldanghomil. Among triticale varieties PRESTO and NAGISTRAL showed earlier heading dates than Shinkihomil. 4. All the triticale varieties showed superior yield components to Paldanghomil. Among triticale varieties LASKO and CLERCAL shpwed better yield compornents than Shinkihomil.

Triticale silage의 醱酵品質에 미치는 生育時期의 影響

윤승길 안성산업대학교 2002 論文集 Vol.33 No.-

To assess the silage quality of triticale, three triticale accessions(Moniko, Presto, Tewo), two wheat accessions(Kitami 66, Chiokukomugi) and three rye accessions(Amilo, Warko, Mardar) were harvested in the heading-, milk-, dough- and ripe-stage, respectively. Dry matter and quality related factors were evaluated. 1. Triticale ensiled at the milk stage showed the lowest fermentative quality than the other stages. However, the triticale ensiled after dough stage had low lactic acid, showing relatively high silage quality. 2. It also was concluded that differences in the silage quality among the tested species were more significant than among the varieties within species.

This experiment was conducted to establish the cultural method of triticale as a whole crop silage by evaluating the effect of seeding date on forage yields and feeding value. 1. Heading date, flowering date, and the dough stage of development came significantly earlier as triticale was seeded earlier. 2. Soilage, dry matter yields and percent dry matter significantly varied with seeding dates and was increased by early seeding. 3. There were no significant differences among different seeding dates in the contents of crude protein, crude fat, crude fiber, crude ash, NFE and TDN. However, TDN yield was significantly reduced by delayed seeding. 4. Macro-mineral contents were not affected by seeding date.

보리에서 광호영 및 수축절수의 유전양식과 이들 두 형질의 연관관계를 구명하여 양질 다수성 품종개량의 효율 제고를 위한 기초자료를 얻기 위하여 호영이 넓고 수축절수가 적은 Triple Bearded Club Mariout(T.B.C.M) 품종과 호영이 좁고 수축절수가 많은 특성을 가진 강보리를 교잡하여 이들의 양친과 F_1, F_2세대 5개 조합을 공시하여 실험한 결과는 다음과 같다. 1. 보리의 광호영은 단순 열성으로서 1쌍의 대립유전자에 의해 지배되었다. 2. 수축절수는 많은 것이 우성, 적은 것이 열성으로서 1쌍의 대립유전자에 의해 지배되었다. 3. 수축절수와 호영을 지배하는 유전자는 동일염색체내 연관되어 있으며, 조환가는 조합마다 다소 차이가 있으나 15.8∼18.0% 범위로 비교적 가깝게 좌위하고 있는 것으로 추정되었다. This experiment was conducted to obtain basic genetic informations which could be used for breeding of barley for better quality an high yield. The data for this study were obtained from cross among Triple Bearded Club Mariout(T.B.C.M) and five released varieties. T.B.C.M. has wide outer glume and a low number of rachis internode, while five released varieties has narrow outer glume and a high number of rachis internode. The parents, F_1 and F_2 lines resulted from cross among T.B.C.M. and five released varieties were studied in field experiment. And the inheritance modes of outer glume, number of rachis internode, and their linkage relationships were determined. The wide outer glume in barley was a simple recessive gene. High number of rachis internode is shown to dominate over low number of rachis internode. The genes for number of rachis internode and outer glume appeared to be linked closely. Based on recombination analysis, recombination values between two characters linked were 15.8~18.0% with some variation depending on varieties used.

박종태,신경진,양윤석,우광만,이숭덕,이승환,이정빈,정연보,조승희,한길로,한면수,홍승범 大韓法醫學會 2001 대한법의학회지 Vol.25 No.1

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Effect of electron beam irradiation on development and reproduction of Spodoptera litura

Seung-Hwan Yun,Changmann Yoon,Hyun-Na Koo,Gil-Hah Kim 한국응용곤충학회 2011 한국응용곤충학회 학술대회논문집 Vol.2011 No.10

The effects of electron beam irradiation on development and reproduction of Spodoptera litura were examined. Eggs, larvae, pupae, and adults were irradiated at target doses of 30, 50, 100, 150, 200, and 250 Gy. When eggs were irradiated with 100 Gy, egg hatching was perfectly inhibited. When irradiated to the larvae, pupation was inhibited at 100 Gy and larval period was delayed. When irradiated to the pupae, emergence was inhibited at 100 Gy and above. When irradiated to the adults, longevity and fecundity did not show any differences. However, egg hatching was strongly decreased at 100 Gy and above. Also, electron beam irradiation was not induced the instantaneous death of S. litura. The levels of DNA damage in S. litura adults were evaluated using the alkaline comet assay. Our results indicate that electron beam irradiation increased levels of DNA damage. These results suggest that electron beam irradiation induced abnormal development and reproduction by DNA damage in S. litura.
