外源添加抑制剂对芦蒿吸收Cd和Pb的影响
Effect of Additive Inhibitor on the Cd and Pb Uptake of Artemisia seleirgensis
摘要
Abstract
Artemisia seleirgensis is a popular vegetable in Nanjing. It provides people with kinds of vitamines, celluloses and minerals. However, it is easily contaminated by heavy metal, which is harmful to people' s health. So it is very important to study on the mechanism of heavy metal absorption of A. Seleirgensis. To reduce heavy metal adsorption and develop pollution-free vegetables, the paper investigated the effect of the inhibitor of respiration, P-type ATPase inhibitor, ion channels inhibitor, protein synthesis inhibitor on Cd and Pb uptake in A.seleir-gensis. The results showed both the respiration inhibitor NaN_3 and P-type ATPase inhibitor Na_3VO_4 could inhibit Cd and Pb uptake, which showed properly initiative Cd and Pb uptake in the plant. Ca~(2+) ion channel inhibitor LaCl_3 inhibited Cd uptake of A.seleirgensis in root, while did not inhibit Pb uptake, which demonstrated Cd uptake of A. Seleirgensis was related to Ca~(2+) ion channel, while Pb uptake was not. Cd and Pb uptake of A.seleirgensis were inhibited by the protein synthesis inhibitor cycloheximide, showed that Cd and Pb uptake related to inducement synthesize and activity of protein and enzyme. The results provided the theoretical basis on heavy metal reduction of A.seleirgensis, and it had practical significance to improve the health of people.关键词
