摘要：
The flowering stage is the key yield determinant period of soybean. Short-duration water stress occurring during this stage significantly reduced soybean development and final productivity. Seed treatment with uniconazole powder application plays an important role in alleviating the adverse effects of dry soil on plant development. In order to explore effects of uniconazole on soybean morphological characteristics and yield under drought stress, different rate of uniconazole powder were examined under developing gradually drought stress during flowering stage. The yield of soybean decreased under drought, uniconazole application increased yield. All results suggest that 4 mg/kg is the optimal uniconazole application rate under drought for soybean at the flowering stage.
