摘　　要：在盆栽试验条件下，研究了不同质量浓度丁二酸浸种对玉米干物质积累和运转的影响．结果表明，适宜质量浓度的丁二酸浸种既有利于玉米根、茎、叶、鞘等器官干物质的积累。又能提高贮藏物质向玉米子粒转运量和转运率，明显增加玉米子粒干物质积累量．本试验条件下，丁二酸适宜浸种质量浓度为300～400mg·L^-1．In pot experiments, effects of soaking seeds with succinic acid on the accumulation and transportation of dry matter in summer maize were studied in this paper. The results showed that the suitable concentration of suecinic acid could promote the accumlation of dry matter in roots, leaf, stem and sheath,and enhance the grain translocation amount and efficiency at the same time. In this experiment the concentration of succinic acid is 300 -400 mg· L^-1.
