FIGURE 5.

(A) Spatial distribution of the estimated scores of each replicate and treatment in relation to the Principal Component 1 (PC1) and the Principal Component 2 (PC2) and their respective percentages of the total variance explained by each of the components in relation to the lignin accumulation in stems. Dashed lines on the right grouping has been shaded plants. (B,C) Estimated scores of each replicate and treatment in relation to the Principal Component 1 (PC1) and the Principal Component 2 (PC2) and their respective percentages of the total variance explained by each of the components in relation to the lignin accumulation in stems. For details of treatments, see Figure 1. Different capital (full sunlight) or lowercase (shade) letters over bars indicate statistical difference between treatments on similar light regimes by Duncan’s test (P < 0.05). Asterisks indicate statistical difference between lights on similar GA regimes by Duncan’s test (P < 0.01). (n = 6 ± SE).
