- 摘要:
- 以婆婆纳(Veronica didyma Tenore) 为试材,采用原子吸收分光光度法,研究不同铅浓度胁迫对婆婆纳生长和富集情况的影响,探索婆婆纳在铅污染区修复方面的利用价值。结果表明:5、15、30 g/L铅浓度处理对婆婆纳的生长起促进作用,45 g/L铅浓度处理对婆婆纳的生长有抑制作用。不同器官组织对铅的吸收存在差异性,根系对铅的积累最强,在60 g/L处理下根系铅积累量最高,其值为470.82 mg/kg;不同浓度处理下,婆婆纳的富集系数均小于1。
- Abstract:
- Taking Veronica didyma Tenore as material,by means of atomic absorption spectrometry,the influence of different Pb concentration on the growth and enrichment of Veronica didyma Tenore were investigated,in order to explore the value of Veronica didyma Tenore on remediation of lead in pollution area.The results showed that 5 g/L,15 g/L and 30 g/L concentrations of lead played a driving role on the growth of Veronica didyma Tenore,but 45 g/L concentrations of lead inhibited the growth of Veronica didyma Tenore.There were differences among the different organs of Veronica didyma Tenore on the absorption of lead.The root was the strongest to the accumulation of lead.In 60 g/L concentrations of lead,the value of accumulation of root was the highest,which was 470.82 mg/kg.The enrichment coefficients of Veronica didyma Tenore were less than 1 at different concentrations.
