Abstract: 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.

摘要： 介绍了一种简易的测量水稻硅含量的方法，其主要特点为准确、方便、能批量化测定水稻硅含量。以珍汕97B/密阳46重组自交系群体，两次重复，共498个株系的谷壳、剑叶和茎秆为材料，验证了该方法的可靠性。每份材料测定2份样品，两次测定结果达极显著正相关（P<0.01），线性相关系数分别为0.97954、0.97026和0.98848。取10份代表性样品进行了高温碱熔解法的测定，两种方法测定结果高度一致， r = 0.9993。
