Two-dimensional scatter plots of LDA results based on different data types at various days after anthesis (DAA) under nitrogen treatments. (A–C) Morphological characteristics, (D–F) Multispectral features, (G–I) Autofluorescence features, and (J–L) Integrated dataset analysis. Each column from left to right represents CK, N1, and N2 nitrogen treatment levels, with data points colored according to DAA (16, 23, 30, and 36 days). Different colored ellipses represent DAA, with solid and dashed ellipses indicating SG and IG positions, respectively. The percentages in parentheses show the proportion of variance explained by each LD axis
