초록

새싹채소의 종자발아와 생장에 미치는 셀레늄 농도 처리(삽입) 효과와 흡수특성을 구명하기 위하여, 대표적인 채소류인 배추, 상추, 청경채 및 을 이용하여 다양한 셀레늄 농도 (0, 1, 5, 10, 25, 50, 100 mg $L^{-1}$ 를 처리하였다. 종자발아는 배추, 청경채 및 갓에서 처리 농도가 증가함에 따라 억제되었지만, 상추의 경우 큰 영향을 받지 않았다. 싹의 생장에 미치는 셀레늄의 효과는 배추, 상추, 청경채 및 갓의 경우, 지상부 길이, 뿌리 길이, 생체중 및 엽록소 함량 등의 생육특성에 있어서 낮은 처리 농도 (1 mg $L^{-1}$)에서 오히려 약간의 생장 촉진 효과를 보이거나 거의 차이가 없었다. 5 mg $L^{-1}$ 이상의 농도 처리 시에는 농도가 높아짐에 따라 심각한 생육 억제 현상을 보였다. 식물체내의 셀레늄의 흡수 특성은 셀레늄을 각각 1${\sim}$25 mg $L^{-1}$ 처리 시 배추는 0.11${\sim}$1.15, 상추는 0.16${\sim}$0.61, 청경채는 0.13${\sim}$1.31 그리고 갓은 0.14${\sim}$1.13 mg $g^{-1}$dw 범위에서 셀레늄 처리농도가 높아짐에 따라 점진적으로 증가하였다. 따라서 본 연구의 결과에 의하여 1${\sim}$5 mg $L^{-1}$ 범위의 낮은 농도의 셀레늄 처리가 셀레늄 함유된 기능성 새싹채소의 생산을 위한 기초 자료로 활용 될 것으로 판단된다.

This study was carried out to investigate the effect of selenium treatment on the growth of vegetables sprout. Four vegetables, such as cabbage, lettuce, pak-choi and leaf mustard were examined under various selenium treatments (0, 1, 5, 10, 25, 50, 100 mg $L^{-1}$). Seed germinations in cabbage, pak-choi and leaf mustard were significantly inhibited at high concentration of selenium treatment. However, seed germination in lettuce was not much inhibited. Growth characteristics, such as soot length, root length, fresh weight and chlorophyll contents, were not much decreased at 1 mg $L^{-1}$ of selenium and then significantly inhibited with the increase of selenium concentration at above 5 mg $L^{-1}$ in all four vegetables. The selenium content increased linearly with the increase of selenium concentration. At the range of 1 to 25 mg $L^{-1}$ of selenium treatment, selenium contents in vegetables were 0.11 to 1.15 of cabbage, 0.16 to 0.61 of lettuce, 0.13 to 1.31 of pak-choi and 0.14 to 1.13 mg $g^{-1}$dw of leaf mustard, respectively. These results showed that treatment of selenium with the range of 1 to 5 mg $L^{-1}$ could be used to produce the selenium enriched vegetable sprouts.
