查询词典 chlorophyll

The results indicated that the accumulation of Mn in the cell wall (accumulation rate as high as 36.34%) and the vacuole of the leaves (accumulation rate as high as 65.64%) might be one of the mechanisms of tolerance and hyperaccumulation of Polygonum hydropiper to Mn. Most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. The content of chlorophyll a did not change under different Mn concentration treatments except that its content decreased remarkably when Mn concentration was 8000μmol/L in solutions. The membranes were not banned by Mn when its concentration was less than 5000μmol/L in solutions; Under different Mn concentrations of Mn, the content of their soluble proteins of leaves had changed at some stage. The activity of SOD and POD were gradually improved with the increasing of Mn concentration, which could eliminate activated oxygen free radical, This might be the other physiological mechanism of tolerance and hyperaccumulation of Polygonum hydropiper responding to Mn.

结果表明：锰在水蓼叶片非活性代谢部分的积累是其解毒耐锰的主要机制之一；水蓼叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在；在锰浓度处理为8000μmol/L时，叶绿素a含量显著降低，而在其它处理条件下，叶绿素a无明显变化；在锰处理≤5000μmol/L时水蓼叶片的细胞膜还没有受到明显伤害；水蓼叶片的可溶性蛋白含量随锰处理浓度不同而变化，说明植物在代谢和结构上发生了调整；随锰处理浓度的增加，水蓼叶片SOD和POD活性提高，保护酶活性的提高又可清除活性氧自由基，这是水蓼耐高锰和累积锰的一种生理响应机制。

With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.
