摘要： Boron (B) deficiency influences sugar beet development and productivity. A hydroponic set up of experiment was conducted by utilizing different B concentrations to study the impact of different morphological and physiological responses of sugar beet seedlings under B deficiency. The results showed that B deficiency (14 days of stress) inhibited the growth of different plant parts of sugar beet. The B deficiency significantly increased the leaf specific weight (SLW) and the root-shoot ratio of sugar beet seedlings. The activities of peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD) showed a decreasing tendency under B deficiency, while the contents of hydrogen peroxide (H2O2) and superoxide (O-2(-)) increased with B concentration. Malonaldehyde (MDA) and proline contents were induced at B deficiency. In conclusion, B deficiency significantly reduced dry weight and leaf area, resulting in stunted sugar beet seedlings. It was manifested by a significant decrease in antioxidant enzyme activities and accumulation of ROS in the plant cells, inducing oxidative stress. The current study revealed that B deficiency affects plant growth and various morpho-physiological processes.
