영문 초록

This study was conducted to response the growth, seed yield, nitrogen content and different cation content of two soybean, flooding-tolerant cv. Pungsannamulkong (PNSK) and flooding-sensitive cv. Tawonkong (TWK) when these were subjected to flooding stress at R1 stage for cultivation in paddy field. Flooding, underground water levels (UWL) of 0 cm, 10 cm and 40 cm, was experi-mented from flowering time to harvest time. The dry matter and seed yield of soybean with UWL of 0 or 10 cm declined in comparison with UWL of 40 cm and these were more reduction in TWK than in PNSK. The amount of nitrogen uptake decreased in higher UWL and there was a high significant relationship (R2=0.872) between nitrogen content and seed yield at flooding stress. K content of leaf and stem in soybean plants had a small change with UWL but Ca content had a decrease (leaf and stem) or increase (root). Mn and Fe content were increased at higher UWL and were more in TWK than in PNSK.
