Spectral reflectance pattern in soybean leaves infected by Mungbean yellow mosaic India virus (MYMIV) through whitefly transmission under artificial conditions and yellowing induced by nitrogen deficiency in pots. Reflectance of a five infected and healthy leaves (n = 5) and b five leaves showing yellowness (n = 5) were measured on adaxial surface and the average reflectance was plotted. The significance of reflectance for infected/yellowness and healthy leaves was determined by ANOVA and Dunnett’s means test
