多壁碳纳米管对水蕨生理特性的影响
Influence of Multi-walled Carbon Nanotubes on the Physiological Characteristics of Ceratopteris thalictroides(L.)Brongn.
摘要
Abstract
Based on previous studies,this research used the fern model plant Ceratopteris thalictroides as test material to investigate the effects of different concentrations of multi-walled carbon nanotubes(MWCNTs)on the physiological characteristics.The results showed that compared with the control group(0.0 mg/L MWCNTs),the T1(0.5 mg/L MWCNTs),T2(1.0 mg/L MWCNTs),and T3(2.5 mg/L MWCNTs)treat-ments had extremely significant(P<0.01)effects on leaf SOD activity,while the T4(5.0 mg/L MWCNTs)treatment had a significant(P<0.05)effect.Among them,SOD activity was the lowest in the T2 group(636.18 U/g),and POD activity was the lowest in T4 group(319.06 U/g);MWCNTs treatment had no significant effect(P>0.05)on the contents of MDA and soluble sugar,both showed a fluctuating trend with the concentration of MWCNTs increased.DAB staining resulted in a blue-purple color.The comprehensive results indicate that treat-ments with 0.5-5.0 mg/L MWCNTs affect the physiological characteristics of C.thalictroides sporophytes,and SOD played a major role when exposed to the treatment of multi-walled carbon nanotubes;under high concentration treatment,the activities of SOD and POD changed signifi-cantly,and MDA content rose to the highest level,resulting in the"high concentration inhibition"phenomenon.关键词
