Abstract:

To guarantee the emergence rate and production potential of sugar beet seed in field, it is necessary to test the seed vigor before planting and select the seed with high vigor for planting. The sugar beet seeds were aged by high temperature treatment, and then the intelligent detection model of seed vigor was constructed based on five near-infrared hyperspectral pretreatment methods: standard normal transformation (SNV), de-trending correction (DET), Savitzky-Golay smoothing (SG), first-order difference (1D) and second-order difference (2D), so as to obtain the predicted seed germination rate. The actual germination rate was obtained by germination test of aged beet seeds. The results show that the intelligent detection model established by the first-order differential pretreatment of sugar beet seeds has the best prediction performance, and its prediction accuracy could reach 91.92%. Comparing the actual germination rate of untreated sugar beet seeds with the prediction results of the intelligent model established by the first-order difference pretreatment method, it is found that the prediction accuracy of the model is 88.2%. It is concluded that the near infrared hyperspectral technology is a new method for rapid and nondestructive determination of crop seed vigor.
