摘要

以洛旱6号、豫麦25、豫麦18、豫农949、新麦21及许农5号为试验材料

通过营养液培养法

研究了镉胁迫对其幼苗生物量积累以及Cd2+、Zn2+与Mn2+吸收的影响。结果表明

与正常生长小麦相比

低Cd2+(≤30μmol/L)浓度下

除许农5号地上部生物量有所下降外

其余品种的地上部和地下部生物量均呈上升趋势。中、高Cd2+(≥60μmol/L)浓度下

所有品种的生物量呈下降趋势

所有小麦品种体内Cd2+的含量均随着Cd2+处理浓度的增加而不断增加

而且

根系内Cd2+的含量均明显高于地上部。随着Cd2+处理浓度的增加

所有小麦品种地上部Zn2+的含量均不断增加

地下部Zn2+含量的变化品种间存在差异。地上、地下部Mn2+的含量则随处理浓度增加而不断降低。
