In Vivo Phenotyping for the Early Detection of Drought Stress in Tomato

Figure 11

Biplot showing the PCA results. The first two PCs display 71.1% of the total phenotypic variation observed in 11 days of drought stress. The component scores (shown in points) are coloured according to the agronomic groups (red, drought-stressed plants; green, control plants). The component loading vectors (represented in lines) were superimposed proportionally to their contribution. : compactness; GI: green index; SC: stomatal conductance; : sensor response; NI: NIR intensity; DB: digital biovolume.
