分别用 3,6 ,6 0 μmol.L-1Nd(NO3 ) 3 处理油菜苗 .测定其叶绿素含量、光合速率及叶绿体膜上Mg2 + - ATPase活性 ,并观察叶片细胞的超微结构变化 .结果表明 ,低浓度钕 (3μmol.L-1)能促进光合作用 ,而高浓度钕则可抑制光合作用 .钕对油菜光合作用的影响是由于钕对叶绿体结构及叶绿体膜上Mg2 + - ATPase的作用所引起的
The Rapeseed seedlings were treated with 3, 6, 60 μmol·L-1Nd (NO3) 3 respectively, and their chlorophyll content, photosynthetic rate and Mg2 + - ATPase activity in chloroplast membrane were measured and the ultrastructural changes of leaf cells were observed. , Low concentration of neodymium (3μmol.L-1) can promote photosynthesis, while high concentration of neodymium can inhibit photosynthesis.The effect of neodymium on photosynthesis of rapeseed is due to the effect of neodymium on chloroplast structure and chloroplast membrane Mg2 + - ATPase caused
