Studies on accumulation of 133Cs and 88Sr in Vicia faba Linn and irradiation damage effect
The different concentrations of ,133,Cs and ,88,Sr accumulated by ,Vicia faba Linn, and its irradiation damage effect were studied during cultivation in hydroponic condition. The accumulation of ,133,Cs and ,88,Sr was determined by FAAS, the distribution in different organs of ,Vicia faba Linn, and physiological effect of ,133,Cs and ,88,Sr were investigated. The results show that at low concentration level the ,133,Cs and ,88,Sr taken by above-ground and root of ,Vicia faba Linn, increase with the increment of their initial concentration and the accumulation relationship of contents is roots ,>, above-grounds and ,133,Cs ,>,88,Sr. When the plantlets exposed to ,133,Cs or ,88,Sr, the accumulated amounts increase rapidly at begin then increase slowly along with the cultured time. With the increment of initial concentration the root activities tend to increase at first and then decrease. It has been found that the MDA contents in leaves increase with the experimental time and are higher than that in root while the contents of soluble sugar of ,88,Sr treated group are higher than that of ,133,Cs treated group.
