(A, B) Comparison of optimized radial conductivities (k_r) and axial conductances (K_x) determined in the current study with existing literature values for lupin plants. The hydraulic properties of the taproot are indicated by the subscript T, and those of the lateral roots by the subscripts Ly and Lo for young (0–5 d old) and old segments (5–25 d old), respectively. The best root hydraulic properties as determined in the current study are compared with the ranges of values reported by Doussan et al. (2006), Bramley et al. (2007), Zarebanadkouki et al. (2016), and Meunier et al. (2018b). (C) Root system architecture at 25 d after sowing.
