Appendix B. Maximum vessel lengths and lengths of segments used to construct vulnerability curves.

TABLE B1. Maximum vessel and segment lengths used to construct the vulnerability curves of 12 dry tropical tree species of Chamela, Mexico. Segments that were used to calculate the mean water potential at which 50% of hydraulic conductivity was lost by means of the air injection method (Sperry and Saliedra 1994) were always longer than the maximum vessel length to avoid the artifact in the technique that were described in Choat et al. (2010) and Cochard et al. (2010).
