Additional file 1 of Seed viability testing for research and conservation of epiphytic and terrestrial orchids

Additional file 1: Table S1. The mean probability of finding viable seeds (PSV) without sterilization (NS) and with sterilization (S) of seeds, and the difference between NS and S for Evans blue test (EB), Fluorescein diacetate test (FDA) and Tetrazolium test (TTC) for each of the 20 orchid species. The viability test exhibiting maximum and minimum difference between NS and S for each species. The number of species having maximum and minimum difference for each viability test is summarized at the end. Figure S1. Box plot for the probability of finding viable seeds (PSV) after subjecting seeds of five epiphytic (first row) and 15 terrestrial orchid species (second to last row) to three seed viability tests; Evans blue test (EB), Fluorescein diacetate test (FDA) and Tetrazolium test (TTC) without sterilization (NS) and with sterilization (S) of seeds. Viability tests marked with the same letters were similar statistically (P > 0.05) while those with different letters were not.
