SEED DISCRIMINATION METHOD AND SEED DISCRIMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a seed discrimination method and seed discrimination device capable of easily and quickly selecting seeds having a high germination rate.;SOLUTION: The method for discriminating measurement object seeds S using light includes: applying light L1 having a wavelength region of visible light from a light source part 10 to a measurement object seed S placed on an upper face 2s of a stage 2; detecting light including light reflected and/or scattered by a seed coat of the measurement object seed S to which the light L1 is applied, as detection light L2; analyzing detection light spectrum created on the basis of spectrum data obtained from the detection light L2; and discriminating a state of the measurement object seed S on the basis of the analysis result. The light including the wavelength region of the visible light can be detected as the detection light L2. Whether the measurement object seed S is a quickly-germinating seed or not can be thus acquired by analyzing the detection light spectrum based on the detection light L2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
