From: Quantitative phenotyping and evaluation for lettuce leaves of multiple semantic components
The hierarchical clustering and classification of positive leaves using the PCs of GEO (A), CLR (B), VEN (C), and COM (D). The leaves were clustered into four groups (the cluster id from 0 to 3, from top to bottom). Five leaves were randomly selected from each group and arranged in one row. The leaf number of each group is illustrated in the lower right corner, and statistical traits of each group are shown in the lower-left corner
