3.1. Seed production and seed weight
The differences in both seed production and seed weight between pollen-supplemented and naturally pollinated flowers at the community level were statistically significant (permutational MANOVA; Pseudo-F=3.99, p=0.023, and Pseudo-F= 6.92, p= 0.005, respectively). At the species level, we found a statistically significant positive increase in seed production after pollen supplementation in seven species (i.e. Table 1): Anemone nemorosa , Lysimachia vulgaris , Lychnis flos-cuculi , Potentilla palustris ,Aegopodium podagraria , Ranunculus auricomus , andStellaria graminea . The mean weight per seed of the pollen-supplemented flowers was significantly higher in two species,Lychnis flos-cuculi and Cardamine pratensis . The capsula weight after the pollen supplementation significantly increased inDactylorhiza majalis . PLs for all individual species are presented in Fig.1.
