Were extracted by different extracting solvents in lab, the results indicated that with the increasing of Mn concentration levels, the speciation of Mn in their roots transform from H2O-extractable species to HCl-extractable species and NaCl-extractable species, showed increases of Mn of oxalate binding and pectate binding or prontein binding in cell wall of roots; Mn of H2O-extractable species were 34.55～50.26% of total Mn in stems and increased with the increasing of Mn concentration levels, which benefited upward transport of Mn; Percentage of Mn of H2O-extractable species were 38.55～44.19% and Mn of HCl-extractable species were 20.66～28.74% to total Mn in leaves, suggesting that most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. 5. Chlorophyll in leaves of Polygonum hydropiper L.
不同的提取剂对水蓼根、茎、叶的提取结果表明，随着锰处理浓度增加，水蓼根中Mn由水提取态向盐酸提取态和氯化钠提取态转化，说明根细胞壁结合的草酸盐和果胶酸盐或蛋白质结合态的Mn含量随锰处理浓度的增加而增加；在茎中，水提取态锰含量占总锰的34.55-50.26%，且随锰处理的增加其水提取态锰的比例增加，这有利于锰向上运输；水蓼的叶片中，水提取态锰占总锰的38.55-44.19%，盐酸提取态锰占总锰的20.66-28.74%，说明叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在。

Their Mn accumulated-concentration of shoots were as high as 26.84 mg·plant-1 and Mn concentration of their leaves were 24447.1 mg·kg-1 when Mn concentration was 15000μmol·L-1 in solutions under the condition of their grow 48d in aquicultural experiments. Their biomass decreased with increasing of Mn concentration levels, the differences of their biomass of shoots were remarkably differrent (P=0.05), comparing control.

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。
