  • Method and apparatus for estimating quality of grains
    Patent number: 6208420
    Abstract: A method and an apparatus are provided for estimating a quality of grains to be harvested from a grain plant in the future, during a growth period prior to the harvesting. The method comprises the step for establishing a quality conversion coefficient for estimating a specific quality of grains after the harvesting based on absorbencies relating to the specific quality of the grains obtained by irradiating light having predetermined wavelength regions on a leaf of a grain plant in growth at a predetermined time during the growth period of the grain plant and the specific quality obtained from the same grains after the harvesting, and the step for estimating the quality of the grains to be harvested in the future based on said quality conversion coefficient and absorbencies relating to said specific quality obtained from a leaf of the grain plant presently growing at the predetermined time.
