摘要： 在盆栽试验条件下,研究了丁二酸浸种对玉米根系生长和生理特性的影响。结果表明,适宜浓度的丁二酸浸种可明显促进玉米根系生长,增加根系生物量,改善根部性状;明显抑制根系膜脂过氧化作用,增强根系中SOD活性,降低MDA含量。丁二酸适宜浸种浓度为200～400 mg/L。

Abstract: With the pot experiments, effects of soaking seeds with succinic acid on growth and physiological characteristic of maize roots were stuied in this paper.The results showed that the applications of succinic acid improved the growth of root and enhanced the root activity of maize.The higher activity of SOD and the lower content of MDA were found when the concentration of succinic acid treated with 200-400 mg/L obviously, it was good for maize root to sharpen lipid peroxidation degree and raise the ability to resist disease at latter growing stage．

Key words: Succinic acid, Soaking seed, Maize root, Growth, Physiological characteristic
