Fig 8. Hierarchical cluster analysis with standardized data of Si, C, N, and P concentrations, C: N, C: P, and N: P ratios; use efficiencies of C (CUE), N (NUE), P (PUE) and dry matter yield (DM) for pre-sprouted sugarcane seedlings under absence (control) and presence (−0.6 MPa) of water deficit (WD) in the short-term and under three forms of Si supply (Si via nutrient solution [SiR], Si via foliar spraying [SiL], and Si absence [−Si]).
