Abstract
The reproductive success of orchids is traditionally estimated by
determining the fruit-set of individuals. Here, we investigated both the fruit
and the seed production of three orchid species and the factors that may affect
individual fruit-set, like pollination strategy, individual traits or the
annual amount of precipitation. The species (Dactylorhiza sambucina (L.) Soó, Dactylorhiza
majalis (Rchb.) P. F. Hunt & Summerhayes and Platanthera bifolia (L.) L. C.
M. Richard) were studied in three consecutive years (2010–2012) in the Bükk
Mountains, Hungary. All the three species were proved to be non-autogamous by a
bagging experiment. Data analyses showed significant differences between seed
numbers but not between fruit-sets of species. There was no statistical
difference in individual reproductive success between wet and dry years
however, the effect of the annual amount of precipitation is significant on the
population level. Comparison of published fruit-set data revealed accordance
with our results in P. bifolia, but not in D. sambucina and D. majalis. We
assume that the surprisingly high fruit-set values of the two Dactylorhiza
species may be due to the fact that the pollination crisis reported from
Western European countries may not be an actual problem in the Bükk Mountains,
Hungary.
