Fig. 4.

Percentage of imbibed seeds (mean ± s.e.) of (A–C) G. carolinianum and (D–F) G. dissectum stored under dry and wet conditions (as indicated) under temperature sequences: (A, D) alternating; (B, E) daily maximum; and (C, F) daily minimum temperature simulating natural temperature conditions of each month. Different upper- and lower-case letters indicate significant differences in imbibition percentages between the incubation temperatures under dry storage and wet storage, respectively (P < 0·05).
