From: Seed germination of Agave species as influenced by substrate water potential
Time-course of cumulative germination of Agave spp. seeds in substrate at -0.03 MPa (A), -1.0 MPa (B), and -1.5 MPa followed by -0.03 MPa (shaded area; C), in the dark and at 25°C. A. americana var. marginata (crosses), A. asperrima (red triangles), A. cupreata (green triangles), A. duranguensis (gray stars), A. lechuguilla (blue circles), A. salmiana (pink squares) and A. striata (blue diamonds), n = 50.
