콩나물의 품종, 뿌리발생 및 재배일수에 따른 asparagine 함량 변이 = Change of asparagine content in soybean sprouts by variety, root growth, and cultivation period

국문 초록 (Abstract)

숙취해독에 탁월한 효과를 지니는 asparagine 함량의 콩나물 계통간 차이와 뿌리 발생량에 따른 차이 및 콩나물 재배기간에 따른 차이를 구명하여 고 asparagine을 가지는 기능성 콩나물 생산과 품종육성을 위하여 국내재래 콩나물 계통의 asparagine함량을 분석한 결과를 요약하면 다음과 같다.
1. 공시된 나물콩 174품종 및 계통의 콩나물에서의 sparagine 함량의 범위 및 평균은 0.38-1.67%, 0.99%(생체수준)로 각각 나타나 다양한 변이를 보였다.
2. 공시된 장려품종과 재래계통의 asparagine함량은 각각 1.29, 0.96% (생체수준)로 재래계통보다 장려 품종에서 높게 나타났다.
3. 백립중별 asparagine함량은 8.1~10.0g범위에서 1.02%(생체수준)로 가장 높은 경향이었으나 유의적인 차이는 인정되지 않았다.
4. 종피색별 asparagine 함량은 갈색종피종이 1.15%(생제수준)로 가장 높았으며 다른 종피종들은 비슷한 경향으로 나타났다.
5. 공시된 장려품종의 asparagine 함량의 범위는 4.08~6.24%(건물수준)로 나타났고, 다원콩(6.24%), 소백나물콩(6.21%), 소원콩(5.95%), 소명콩(5.85%) 순이 었다.
6. 콩나물의 재배일수를 10일로 한 경우 asparagine함량과 관계가 깊은 뿌리발생량이 크게 증가하였다.
7. 재배일수에 따른 asparagine함량은 5일재배와 10일재배에서 각각 0,68%, 1.21%(생제수준)로 나타나 재배 일수간 asparagine 함량에는 고도의 유의적인 차이가 인정되었다.
8. 콩나물의 하배측 부위에서 재배일수가 증가할수록 asparagine 함량도 증가하여 2일 재배시 2.91%(건물수준)이던 것이 14일 재배시에는 15.68%까지 증가하였다.

The varietel difference, effect of root amounts and cultivation duration on the asparagine content of soybean sprouts, which is known to have the excellent detoxifying effect of ethanol, were investigated for developed varieties and indigenous sprout lines to establish cultivation methods of increasing the asparagine content and to develop soybean varieties having high asparagine content. Some of the research results obtained are summarized as follows;
1. Range and mean of asparagine content of 174 germplasm were 0.38~1.67% and 0.99%, respectively, on fresh weight basis.
2. Developed sprout-soybean varieties showed somewhat higher asparagine content of 1.29% than that of indigenous sprout lines of 0.96% on fresh weight basis.
3. No significant difference in asparagine content among the seed size groups was recognized though the highest asparagine content, 1.02% on fresh weight basis was observed in the seed size of 8.1~10.0g/100 seeds.
4. Among the seed coat color groups, soybean of brown seed coat color showed the highest asparagine content (1.15%) on fresh weight basis. No difference was observed among other groups of seed coat color.
5. Range of asparagine content of 174 varieties was 4.08~6.24% on dry weight basis. Soybean varieties that showed high asparagine content were Dawonkong, Sobacknamulkong, Sowonkong, and Somyungkong, with the contents of 6.24%, 6.21%, 5.95%, and 5.85%, respectively.
6. Amount of roots which have the highest asparagine content out of sprout parts was greatly increased up to 10 days of sprout cultivation.
7. Highly significant difference in asparagne content of sprout was recognized between those grown for five and ten days, with the asparagine content of 0.68% and 1.21%, respectively, on fresh weight basis.
8. Asparagine content of hypocotyle part was also highly proportional to days to cultivation; it increased from 2.91% at 2 days of cultivation to 15.68% on fresh weight basis at 14 days of cultivation.
