Effects of Plant Hormones on Accumulation of~(133)Cs in Sunflower (Helianthus annuus L.)

Menglu GUO;Department of Life Sciences,Heze University;  
[Objective] This study was conducted to discuss a high efficient phytoremediation technology for ~(133)Cs pollution.[Method] The effects of 3 exogenous phytohormones on the uptake and accumulation of ~(133)Cs in the seedlings of Helianthus annuus L., which is a kind of hyperaccumulator plant, was further studied in the pot experiments. [Result] The results indicated that the absorption, accumulation and translocation capacities of ~(133)Cs of the sunflower plants could be improved significantly after the application of phytohormones.~(133)Cs contents were higher in leaves and flowers as compared with stems and roots. The accumulation capacities of phytohormones were in order of SAGAIAA. [Conclusion] The absorption capacity,translocation factor and bioaccumulation factor of ~(133)Cs were maximum after the application of SA(100 mg/L).
