摘要
构建稻谷品种特征库的前提是确立稻谷品种形态学差异特征值。通过Image Pro Plus软件量化了31个稻谷品种41种形态学特征值,并运用判别分析法获得了反映稻谷品种差异的9个形态学特征值,即表示几何形状的有4个,分别为Aspect、Area、Axis(minor)和Axis(major),表示颜色的有5个,分别为Density(max)、Density(green)、Density(mean)、Density(blue)和Density(std)。用这9个特征值对31个稻谷品种进行聚类分析,获得的分类结果和用41种形态学特征值进行聚类分析的结果一致,表明这9个特征值能代替41种形态学特征值表达水稻品种之间的差异。
The premise of constructing the rice variety feature database is to establish the morphological difference characteristics of rice varieties.The paper quantified 41 morphological characteristics of 31 rice varieties using Image Pro Plus software,and 9 morphological characteristics that reflected the differences of rice varieties were obtained using the discriminant analysis method.There were 4geometrical shapes(Aspect,Area,Axis(minor),Axis(major)),and 5 color characteristics(Density(max),Density(green),Density(mean),Density(blue),Density(std)).The results obtained by clustering analysis of 31 rice varieties were consistent with the results obtained by clustering analysis of 41 morphological characteristic values,indicating that these 9 characteristic values could replace 41morphological characteristic values and express the differences among rice varieties.
