Results of Beta-Binomial models tested for 20 orchid species. P_via is the viability percentage as the response for each species with serial number 1 to 20 as allocated in the Table 1, for all epiphytic species (1–5), followed by all terrestrial species (6–20). The VT is the viability test, SZ is the sterilization status and VT*SZ is the interaction between VT and SZ. The values marked *** are of highest significance (p < 0.001)
