Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE\´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The effect of N form on growth and uptake of Cr by the hyper accumulator Leersia Hexandra Swartz was investigated in pot experiments. The results indicated that the maximum Cr concentration in the dry root, stem and leaf matter of Leersia hexandra treated with (NH4)2 S04 reached 19546mg kg-1, 3265 mg kg-1, 6118 mg kg-1, which were 1.5 to 4 times the weight of the CK. A higher biomass was obtained when N was supplied as NH4NO3, and biomass difference was not significant between treatment with (NH4)2SO4 Ca(NO3)2 and CK, regardless whether soil applied with 400 mg kg-1 Cr or not. Sugar in plants treated with 400 mg kg"1 was more than that of lOOmg kg-1 among (NH4)2SO4, NH4NO3 and Ca(NO3)2 But the chlorophyll and protein contents were most high when applied with NH4NO3 The results showed that supplying N as NH4NO3 promoted growth best and most high concentration of soluble sugar could possibly provide an adaptive mechanism under adverse circumstances.
