摘要
以小麦为供试作物,分别分析研究稀土元素La、Nd对小麦体内过氧化物酶(POD)和超氧化物歧化酶(SOD)活性的影响。结果表明:不论小麦的地上部分还是地下部分不同浓度的镧、钕对其体内2种酶活性的影响效果差异明显,当La、Nd溶液浓度为10mg/L时,小麦地上部分SOD、地上和地下部分POD活性达到最大值,而当Nd溶液浓度为5mg/L时,地下部分SOD活性达到峰值,且Nd对小麦体内酶的调节效应比La强烈。
Wheat for the test crops, respectively, analysis of rare earth elements La, Nd body on wheat peroxidase （POD） and superoxide dismutase （SOD） activity. The results showed that： no matter what part of wheat on the ground or underground parts of different concentrations of lanthanum, neodymium two of its in vivo effects of activity differences, when the La, Nd solution concentration 10mg / L, the aboveground part of wheat SOD, above and below ground part of POD activity reached maximum, and when the Nd concentration of solution for 5mg / L, the underground sections of SOD activity reached its peak, Nd of wheat and enzyme regulation in vivo effects than La strong.
