Reflectance sensitivity in soybean leaves infected by Mungbean yellow mosaic India virus (MYMIV) a yellowing induced by nitrogen deficiency b reflectance sensitivity to MYMIV infection was computed by dividing the reflectance difference by mean reflectance of healthy leaves and reflectance difference was computed by subtracting mean (n = 5) reflectance of healthy leaves from the mean reflectance (n = 5) of MYMIV infected leaves. The significance of reflectance sensitivities for infected and healthy leaves was determined by ANOVA and Dunnett’s means test
