Figure 11

Principal component analysis (PCA) of plot-specific leaf angle distributions. PCA reveals distinct clustering of states and cultivars, while nitrogen treatment effects are lacking. (A) Complete set of 48 analyzed images representing 2 repetitions (1,2) of 24 parameter constellations - 4 cultivars (B,C,M,P), 3 states (s, m, l) and 2 nitrogen treatments (+, -): The states (color-indexed measurement days) display strong clustering with the strongest separation of the youngest plant state. (B-D) Analysis of each state indicates variety-specific leaf angle distributions resulting in a pronounced clustering of all 4 cultivars (color-indexed) regardless of the measurement day.
