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。

Tion at two-leaf stage,and morphological indexes and physiological indexes of Plug seedlings were measuredand analyzed after treatment.The results indicated that all the treatments did positive effects for improving theseedlings quality compared to control whether in summer or in autumn,and treatment of 200 mg/kg CCC wassignificantly increased in root-shoot ratio,seedling index,root activity,soluble protein and decreased in height,compared to control in summer,while treatment of 100 mg/kg CCC+0.1mg/kg BR was significantly increasedin root-shoot ratio,seedling index,chlorophyll,soluble sugar and decreased in height compared to control inautumn.

结果表明：夏季各处理与对照相比均有不同程度的壮苗效果，其中单独施用200mg/kg CCC的秧苗效果最好，与对照相比，株高显著下降，根冠比增加，壮苗指数显著升高，G值提高，根系活力增大，叶绿素显著增加，可溶性糖显著提高；秋季各处理也均利于提高秧苗质量，其中施用100mg/kg CCC+0.1mg/kg BR的秧苗壮苗效果最好，与对照相比，株高显著降低，根冠比显著增大，壮苗指数上升，G值显著增加，根系活力增大，叶绿素总量和可溶性糖都显著增加，可溶性蛋白有所下降。

The result indicates that with organic fertilizer and inorganic nitrogen fertilizer can obviously increase the leaf dimension coefficient, enhance the content of chlorophyll and soluble protein, improve the SOD activity of flag leaf, depress the content of MDA, postpone the speed of decrepitude of flag leaf,; The status with high content of chlorophyll and leaf dimension coefficient lasts longer with organic fertilizer than with inorganic nitrogen fertilizer and the flag leaf have longer functioning time; the combination of inorganic nitrogen fertilizer and organic fertilizer can substantially postpone the speed of decrepitude of winter wheat.

在国内持续时间最长的肥料长期定位（28年）试验条件下，研究了肥料持续施用下冬小麦花后叶面积系数等生理指标的变化，结果表明施用有机肥、氮肥，可明显增大小麦的叶面积系数，增加叶绿素含量和可溶性蛋白含量，提高旗叶的SOD活性，降低丙二醛的含量，延缓旗叶的衰老；施用有机肥较施用氮肥，叶绿素含量及叶面积系数持续高值时间长，旗叶有更长的功能期；长期氮肥与有机肥配施能显著延缓小麦衰老。

As one of the most important osmoregulation actor, firstly,Proline plays a keyrole in the osmotic potential adjustment in plant cells. Secondly, Proline can preventNaCl from damaging the structure of biomacromolecule in cells. Thirdly, the highdissolubility and non-rejection capability of Proline can enlarge the solution volumnof the cell, so the concentration of salt will be diminished in cytoplasm and the saltstress will be relieved. Forthly, the accumulation of Proline could prevent thedehydrolysis from sap cavity in cytoplasm. Fifthly, the synthesis of plant chlorophyllwill be diminished under the salt stress, but the Proline can provide request ofchlorophyll synthesis.

脯氨酸作为渗透调节剂对植物体细胞渗透势的变化起重要作用：一，在盐胁迫下，脯氨酸在植物体内是一种重要的渗透调节剂，它是一些高等植物和绿藻抗盐和抗旱的主要渗透剂之一；二，脯氨酸可以保护细胞中的生物大分子的结构，使之不被NaCl破坏，并能维持其完整的水合范围；三，脯氨酸的高度溶解性以及其对植物各种酶活性不抑制性，可以扩大细胞的溶解容积，从而降低细胞质液中盐的浓度，减轻盐的胁迫作用；四，细胞质中积累的大量脯氨酸可以防止液泡对细胞质的脱水作用；五，在盐胁迫下，植物叶绿素的合成受到抑制，叶绿素的合成需要脯氨酸。
