摘要:
以水稻(Oryza sativa L.)品种中花11号为材料,分析了0.08 mmol/L Cd(NO3)2、0.4 mmol/L Zn(NO3)2和0.4 mmol/L Zn(NO3)2+0.08 mmol/L Cd(NO3)2处理对水稻幼苗根系生长、CAT活性、SOD活性、活性氧产生、细胞死亡及生长素积累分布的影响。结果表明,3种处理均促进了总根数的增加;3种处理总根长度也增加,但三者之间差异不显著。Zn+Cd处理的CAT活性、SOD活性明显高于其他处理,H2O2和 O+2· 的产生和细胞死亡明显少于单一Cd处理。Zn和Cd互作使生长素的积累和分布与单一Cd或Zn不同,由此可见,Zn对Cd胁迫水稻根系生长的调节与其减少ROS产生并诱导生长素积累和分布的变化有密切关系。
