摘要
采用土培的方法,研究了污水胁迫对小麦幼苗叶片和根DNA含量及DNA增色效应的影响。结果表明,低浓度污水处理能提高叶片及根DNA含量,DNA增色效应略有下降;高浓度污水使小麦叶片及根中DNA的含量减少、DNA增色效应显著降低。
The effect of sewage water stress on the content and hyperchromicity of DNA in wheat seedlings was investigateq with soil pot cultivation. The result showed that low concentration of sewage water could increase the DNA content in leavet and roots of wheat seedlings, and slightly lowered the hyperchromicity of DNA; while high concentration treatment significant- ly decreased the DNA content in leaves and roots and hyperchromic effect of DNA.
