Abstract:
The soybean isoflavone has become a worldwide focus,as it has many beneficial functions to human beings.It will be helpful to the genetic improvement of isoflavone content that analyzing isoflavone content and its synthetic substrate content during seeds developing and the reasons of the differences between isoflavone content because of substrate content.The experiment was designed for the above purpose.Six soybean lines with different isoflavone content were planted in this experiment.The content of isoflavone,free phenylalanine,coumarate and naringenin were measured at R5,R6,R7 and R8,respectively.The results showed that the content of isoflavone increased from R5 to R8,and the synthesis and accumulation of daidzein was earlier than genistein.The content of free phenylalanine and naringenin decreased from R5 to R8.The content of coumarate increased from R5 to R8.The correlation coefficients between the isoflavone content and the free phenylalanine content were nearly negative except for R7 stage.All the correlation coefficients between the isoflavone content and the coumarate content were positive.The correlation coefficients between the isoflavone content and naringenin content were a little confusing.
