Effect of Zn Stress on Pteris vittata

Abstract:

Article Preview

In order to investigate the ability of Pteris vittata restoring Zn polluted soil, water cultured experiment is utilized to study the enriching ability of Pteris vittata to Zn, and the detoxification mechanism of Pteris vittata to Zn. The experimental results show that Pteris vittata has certain enriching ability to Zn,and the translation coefficient of Zn in Pteris vittata reaches 1.0. With the increasing of Zn application amount, chlorophyll and soluble sugar contents of Pteris vittata show ascending first and then descending,O2-• and MDA contents continuously ascend,starch content continuously descends.These results show that soluble sugar, starch,O2-• and MDA have detoxification effect,and can enhance the resistance of plant to heavy metal.
