摘　　要：定期测定不同储藏条件下小麦的电导率值,同时用扫描仪采集小麦的表面图像并提取其图像特征,研究储藏过程中小麦的颜色特征参数与电导率的相关性。结果表明:R值、G值、B值、I值、电导率均与储藏时间均呈极显著性相关。与电导率相关性最显著的是I值,其中,瑞星1号小麦的电导率与I值的数学模型:y=1.3E-16x^(8.4613)(电导率值为y,I值为x,下同),R^2=0.869;郑麦8998小麦的电导率与I值的模型:y=1.7E-18x^(9.2785),R^2=0.913;两种小麦的电导率与I值的模型:y=1.0E-8x^(4.5932),R^2=0.676。The conductivity of the wheat stored at different temperatures was detected and the surface image of wheat was collected by scanner. The correlation between conductivity and color character of wheat during storage was analyzed. The result showed that the values of R, G, B, and I, and conductivity were highly correlated with storage time. I value was the most significantly correlated with conductivity. The mathematic model of rui xing number 1 was y=1.3E-16x^8.4613, y represents conductivity value and X represents I value, R2 = 0. 869, while the mathematic model of zheng mai 8998 was y=1.7E-18x^9.2785 R^2=0.913, and that of the two kinds of wheat was y=1.0E-8x^4.5932 R^2=0.676.R^2 =0.676.
