Rapid Determination of Silicon Content in Rice(Oryza sativa)

A method for rapid determination of silicon content in rice was introduced.The reliability of this method was verified by using a recombinant inbred line(RIL) population of rice combination Zhenshan 97B/Milyang 46.Two hundred and forty nine RILs were transplanted in two replications.Simple correlation coefficients of the silicon content in the hull,flag leaf and culm in rice between duplicate samples of 498 rice materials were 0.97954,0.97026 and 0.98848,respectively.Simple correlation coefficient between the silicon content determined by the high-temperature alkaline fusion method and by the present method with 10 representative samples was 0.9993.
