摘要
通过盆栽试验及对植物体内生理生化活性的调查表明,Cd污染可使植物叶片SOD、CAT、PPO、POD和硝酸还原酶的活性下降,但在耐性作物体内,这些酶的活性可以维持;Cd污染可使叶绿体和可溶性总糖的含量降低,但因作物种类不同而异,Cd污染使作物叶片DNA的合成受阻,并在DNA提取物中检出Cd。
AbstractThe result of the test on the physiology and Biochemistry of plantindicated that Cd pollution reduced the activity of SOD,CAT、PPO and ni-trate redactase in the leaves,but it did not affected the activity of theenzvme in the Cd-tolerant plants,Cd pollution decreasd the content ofchloroplast and soluable sugar to different degrees among different plants,Cd pollution made the Synthesise of DNA in leaves difficult and Cd couldbe found in DNA extract.
