The highest flavone content of buckwheat is in its flowers,the mean value is ashigh as 7.4%.After flowering,the value will decrease gradually.The flavone content ofbuckwheat leaves is lower,its mean value is 5.3%,its highest peak appears at the stage o[flowering,then decreasing slowly.The flavone content of buckwheat stems is the lowest,its mean value is 1.0%,no obvious change in the whole growth of the plant.Among thebuckwheat grains,tatary buckwheat grains contain the highest flavone content,the meanvalue is 2.02%.The mean flavone content value of common buckwheat is only 0.23%.Ra-diative treatment-s can increase the flavone content of buckwheat.The formation offlavonid compounds of buckwheat is mainly controlled by PAL activity.

The flavone content of buckwheat leaves is lower, its mean value is 5.3%. Its highest peak appears at the stage o [flowering, then decreasing slowly. The flavone content of buckwheat stems is the lowest, whose mean value is 1.0%, no obvious change in the whole growth of the plant. Among the buckwheat grains, tatary buckwheat grains contain the highest flavone content, the mean value is 2.02%. The mean flavone content value of common buckwheat is only 0.23%. Ra-diative treatment-s can increase the flavone content of buckwheat. The formation offlavonid compounds of buckwheat is mainly controlled by PAL activity.
