We investigated the accumulation of superoxide (O2-) and hydrogen peroxide (H2O2) of soybean roots. Soybeans grown for 1 week were affected by waterlogging for 1 week. One day after removing the stress, tap roots were used for the staining of O2- and H2O2. O2- staining was observed in the middle region of a tap root. The accumulation of H2O2 was detected on plasma membrane in a cortical cell of a tap root. Thus, waterlogging induces the excess accumulation of O2- and O2- derived H2O2 in a cortical cell of a tap root.We also investigated the growth and yields 98 days after sowing of soybean, which was subjected by waterlogging in an early growth stage. The shoot and root growth, grain and nodule weight, chlorophyll contents and photosynthesis rate of fully uppermost leaves decreased compared with those of the control. These results suggest that waterlogging in the early growth stage induces the decrease in growth and the earlier etiolation of leaves in the late growth stage.

研究了大豆根系超氧阴离子（O2-）和过氧化氢（H2 O2）的积累。生长1周的菜豆受1周的涝渍影响。解除胁迫后第1天，取主根进行O2-和H2 O2染色。在主根的中间区域观察到O2染色。在主根皮层细胞的质膜上检测到H2 O2的积累。因此，渍水诱导过量积累的O2-和O2-衍生H2 O2在皮层细胞的主根。我们还调查了生长和产量播种后98天的大豆，这是在早期生长阶段遭受渍水。与对照相比，地上部和地下部的生长量、籽粒和根瘤重、叶绿素含量和全最上部叶片的光合速率均下降。这些结果表明，在生长初期的渍水诱导生长的下降和叶片在生长后期提前黄化。
