摘  要:
[目的]探寻高效修复~(133)Cs污染的技术手段。[方法]通过土壤盆栽试验,研究生长素(IAA)、赤霉素(GA)、水扬酸(SA)3种植物激素对超富集植物向日葵吸收和积累~(133)Cs的影响。[结果]~(133)Cs胁迫下,施用植物激素能显著增加向日葵对~(133)Cs的吸收、转运、积累富集。与茎和根相比,叶、花为主要富集~(133)Cs的器官。3种激素作用下的单株累积量总体表现为SA>GA>IAA。[结论]500 mg/L SA处理下,向日葵对~(133)Cs的吸收量、转运系数、富集系数达到最大值。

摘  要:
[Objective]To discuss a high efficient phytoremediation technology for ~(133)Cs pollution. [Method]Pot experiment was adoped to study effects of three exogenous phytohormones on the uptake and accumulation of ~(133)Cs by Helianthus annuus L.,which is a kind of hyperaccumulator plants. [Result]After using phytohormones,the absorptive,transferred and accumulative capacity of ~(133)Cs by the sunflower plants were obviously higher than the control.~(133)Cs contents were higher in leaves and flowers as compared with stems and roots. The accumulation ability of phytohormones was SA > GA > IAA under the application of three exogenous phytohormones. [Conclusion]The treatment of 500 mg/L SA has maximal absorption dose,transfer coefficient,accumulation factor of ~(133)Cs.
