【目的】明确不同质量分数镉(Cd)胁迫对玉米Cd积累过程的影响效应,揭示玉米种植于Cd污染土壤的生产适用性。【方法】采用田间微区试验设置6个Cd质量分数处理(CK(0.16 mg/kg)、T1(1.70 mg/kg)、T2(4.35 mg/kg)、T3(6.71 mg/kg)、T4(9.78 mg/kg)、T5(15.76 mg/kg)),分别测定郑单985(ZD)和先玉335(XY)玉米在不同质量分数Cd处理下玉米植株中Cd的组织分布特征及各器官含Cd量,分析各组织器官对Cd的富集和转运能力,并建立Cd处理质量分数梯度和玉米各组织器官含Cd量之间的相关性分析。【结果】在Cd污染处理下,Cd量的分布主要集中于根系、叶和苞叶之中,其次为茎/穗轴,籽粒中Cd量占比最少,仅为0.08%~5.12%...
