Effects of the separate digestive processes on mean germinability (viability) and time to first germination in days (TTFG). Standard errors are given between brackets. Significant effects (P < 0.05) are bold. Treatments are abbreviated as in Fig 1 (CTRL = untreated control, C = chemical treatment on intact seeds, I = intestinal treatment on intact seeds, S = scarification, SC = chemical treatment on scarified seeds, SI = intestinal treatment on scarified seeds).
