摘　　要：以2个大穗型小麦品种济麦2和兰麦223为材料,采用盆栽的方式,研究了丁二酸浸种对大穗型小麦苗期和成熟期相关指标的影响,旨在探讨丁二酸对小麦苗期生长和产量的调控机制。结果表明,丁二酸浸种能够增加2个小麦品种叶片的超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性,同时也促进了小麦干物质的积累和分蘖的发生。丁二酸浸种提高了小麦的产量,300 mg/L处理增产最多,济麦2和兰麦223分别比对照增产17.15%和30.44%。In a pot experiment,Jimai 2 and Lanmai 223 were used to study the effect of soaking seeds with succinic acid on leaf physiological parameters at seedling stage and grain yield of large-spike wheat culti-vars under different concentrations of succinic acid. The results showed that soaking seeds with succinic acid could increase the activities of superoxide dismutase（SOD）,peroxidase（POD）,catalase（CAT） and the content of photosynthetic pigment in leaves,as well as the number of tillers and the accumulation of dry matter in roots and leaves,leading to the increase of grain yield. The best dose of succinic acid was 300 mg/L, which increased the grain yield of Jimai 2 and Lanmai 223 by 17. 15% and 30. 44%,respectively.
