Abstract

This study was carried out to investigate the effect of application concentration and period of sodium selenate ($Na_2SeO_4$) in the soil on the growth of garlic. Fresh weight were decreased with the application of higher concentration and longer period of Se compared with the control. The treatment of higher concentration and longer period of Se increased the content of Se in leaf sheath than bulb of garlic after 3 weeks. But, the Se content of garlic was higher in order of bulb, stem, root after 6 weeks of selenium treatment. Se was also detected also in control, the non-treated plot, but the amount was negligible. The content of selenium in the soil was not affected by the concentration and period of selenium application.

토양에 비료 형태로 투여한 셀레늄 농도와 처리기간이 마늘의 생육에 미치는 영향을 구명하고자 본 실험을 수행하였다. 셀레늄의 농도가 높고 처리기간이 길수록 생체중은 대조구에 비하여 감소하였다. 셀레늄의 처리농도가 높고 처리기간이 길수록 3주 후 셀레늄의 함량은 구보다는 엽초에 많이 축적되었다 그러나 처리 6주 후에는 구>엽초>뿌리 순으로 셀레늄의 함량이 높았다. 셀레늄 처리 후 토양에 잔류하고 있는 셀레늄의 함량은 대조구와 차이가 없었다.
