| Abstract: | Objective]The non-destructive test of plum hardness was done.Method]The information of diffuse reflectance spectral on the variety-Dashizaosheng was collected with near-infrared spectroscopy and through the analysis of the information its hardness was evaluated.The optimal model of near-infrared quantitative test of plum hardness was formed through after the quantitative model was established and optimized based on the excluding of abnormal sample.Result]The results showed that the model established in t... |
