摘　　要：为了得到脱绒棉种质量与其表面颜色特征之间的关系,采用CASIO数码相机拍照,利用图像处理技术提取脱绒棉种表面颜色特征,并严格按照GB/T3543.4-1995进行发芽试验,采用线性回归和逐步回归的分析方法,探讨了RGB颜色模型下脱绒棉种颜色特征与发芽势、发芽率之间的相关性。结果表明:多个颜色特征参数与脱绒棉种质量存在显著相关性。该研究为基于RGB颜色模型对脱绒棉种实施快速、有效的分选提供了理论依据。To understand the relationship between quality and extemal color characteristic of delinted cottonseeds, this paper used the technology of digital photography and image color analysis and carried through germinating experiments strictly according to the national standard（GB/T3543.4-1995）. The paper also adopted the single variable linear regression and the stepwise regression analysis methods to discuss the correlation between the germination rate and trend of dehnted cottonseeds and color characteristic under the RGB color model. The experimental results showed that the germination rate and trend of delinted cottonseeds had a distinct relativity with the color characteristic parameters. The result provided a theoretic basis for the delinted cottonseeds sorted under the RGB color model.
