Abstract

This study was conducted to investigate distribution of selenium in Gangwon highland Province and to confirm the effect of sodium selenate added nutrient solution on the selenium content of some western vegetables; beet, broccoli, cabbage lettuce, celery, and parsley. The contents of selenium were distributed from 0.024 to $0.038\;mg{\cdot}kg^{-1}$ in soil of Gangwon highland province. As the selenium content in soil increased, the selenium content in broccoli was increased in highland of Gangwon province. The selenium content of broccoli showed $10.5{\sim}17.9\;mg{\cdot}kg^{-1}DW$ 1311owe4 by celery ($6.02\;mg{\cdot}kg^{-1}DW$). Beet, cabbage lettuce, and parsley contained just about $1\;mg{\cdot}kg^{-1}DW$ in highland of Gangwon province. Some western vegetables grown by fertigation supplied $2\;mg{\cdot}L^{-1}$ sodium selenate were shown better growth and higher selenium content than those of $0\;mg{\cdot}L^{-1}$ sodium selenate supplied treatment(control). The selenium contents of western vegetables supplied $2\;mg{\cdot}L^{-1}$ sodium selenate in fertigation culture for 60 days were $76.2\;mg{\cdot}L^{-1}$ in broccoli, $69.1\;mg{\cdot}L^{-1}$ in parsley, $63.2\;mg{\cdot}L^{-1}$ in celery, $54.2\;mg{\cdot}L^{-1}$ in beet, $8.3\;mg{\cdot}L^{-1}$ in cabbage lettuce. Those selenium content of broccoli, celery, and parsley treated $2\;mg{\cdot}L^{-1}$ sodium selenate were followed the order 4.2 times, 10.5 times and 62.5 times higher in compared to control.

강원도 고랭지 지역의 재배토양과 주요 양채류의 셀레늄 함량을 조사하고 관비재배시 sodium selenate첨가가 작물생육과 셀레늄함량 증가에 미치는 영향을 조사하였다. 고랭지 지역의 토양의 셀레늄 함량은 $0.024{\sim}0.038mg{\cdot}kg^{-1}$의 분포를 보여 전반적으로 낮은 함량을 나타냈다. 각 지역에서 재배된 브로콜리의 셀레늄 함량은 적게는 10.5mg에서 많게는 $17.9\;mg{\cdot}kg^{-1}DW$로 나타났으며, 토양내 셀레늄 함량이 높을수록 재배 작물체내의 함량도 높아지는 경향을 보였다. 셀러리의 셀리늄 함량은 $6.02\;mg{\cdot}kg^{-11}$이었고, 비트, 결구상추 및 파슬리는 1mg 전후로 매우 낮은 함량을 나타내었다. 관비재배시 sodium selenate $2mg{\cdot}L^{-1}$처리구는 무처리구(대조구)에 비해 생육및 작물체내 셀레늄함량을 증진시켰다. $2mg{\cdot}L^{-1}$농도 60일간 관비재배한 결과 양채류의 Se 함량은 브로콜리 $76.2mg{\cdot}L^{-1}$, 파슬리 $69.1mg{\cdot}L^{-1}$, 셀러리 $63.2mg{\cdot}L^{-1}$, 비트 $54.2mg{\cdot}L^{-1}$, 결구상추 $8.3mg{\cdot}L^{-1}$순이었으며 브로콜리는 대조구보다 4.2배, 셀러리는 10.5배, 파슬리는 62.5배가 증가하였다.
