Table 2 Fruit set of the different hand-pollination treatments (bagging, emasculating, out-crossing, geitonogamy) in 2014, natural fruit set in 2014, 2015 and 2018, and viable embryo rate of seeds from geitonogamy, out-crossing and natural fruit in 2014 for the two Habenaria species (mean ± SE). The sample sizes of inflorescences and flowers are indicated in the brackets. Post-hoc multiple comparison tests (a, b, c) were conducted for the natural fruit set and viable seed embryos of H. petelotii and H. limprichtii
