Studies on cadmium uptake, accumulation and tolerance in Salix babylonica 垂柳对镉吸收、积累与耐性的特点分析
The result declares that transmission of VP in willow stem ( salix babylonica) plantlet can be evoked by treating the wood with Naclsolution or by a local burn on the stem. 结果表明,烧伤柳茎或盐胁柳根引起的变异电波,可以通过环剥后的木质部再横向传递至韧皮部(树皮),被表面电极记录下来。
Effects of two pesticides on PPO, POD activity and isozymes in weeping willow ( Salix babylonica Linn) by trunk injection 两种农药树干注射对垂柳叶内PPO和POD活性及同工酶谱的影响
The allocation coefficient trend of Pb and Cd in Salix babylonica was root> stem> leaf. 铅镉在垂柳根中的分配系数大于茎叶。
The results were as follows: 1. Height growth, root growth and biomass of Salix babylonica were all rejected under single and combined Pb and Cd stress, and the inhib function was raised with increase of concentration. 研究结果表明:1.在铅镉单一胁迫和复合胁迫条件下,垂柳高生长、根系生长和生物量均受到抑制,浓度愈大抑制作用也越大。
Fe, Zn, Mn had obvious inhibiting effect on uptake of cupper by Salix babylonica Linn but no apparent inhibiting effect on Salix jiangsuensis CL J-172 when them were equal to copper in inoculum. 在与铜浓度的浓度比值为1:1时,矿质元素铁、锌、锰对垂柳根系吸收铜有明显的抑制作用,而对苏柳172没有明显的作用。
By the end of the summer-autumn stage, the concentration of TN, TP in various part of Pterocarya stenoptera and Salix babylonica showed a sequence of: leavesrootsstems. 在夏秋季试验结束时,枫杨、垂柳幼苗各部的TN、TP浓度均为叶根茎。
Under Pb stress, the production rate of superoxide anion radical, Membrane permeability of Salix babylonica were closely related to MDA, and showed significant positive correlation. 在铅的胁迫下,垂柳的活性氧的产生速率、相对电导率与MDA关系密切,呈显著正相关。
Membrane permeability and content of MDA of Salix babylonica leaf were added with increase of Pb and Cd concentration. 垂柳叶片相对电导率呈和MDA含量随铅镉处理浓度的增加而增加。
The content of TN, TP in the stem was biggest in various part of Pterocarya stenoptera and Salix babylonica. 枫杨、垂柳各部的TN、TP含量均以茎部最大。
The copper transport from roots to stems in Salix jiangsuensis CL J-172 and Salix babylonica Linn was inhibited by water logging stress, the copper content in stem increased earlier and decreased later with increasing of copper concentration in soil. 水淹胁迫会抑制苏柳172和垂柳根中铜向茎中的转运,随着土壤中铜浓度的增加,茎中的铜含量呈向先上升后下降的趋势。
