The role of geitonogamy in the reproduction success of a nectarless dactylorhiza maculata (orchidaceae)

2011

Dactylorhiza maculata is a common terrestrial orchid in Finland. It is nectarless and the seed production is relatively high for a deceptive species. The pollinators of D. maculata do not have frequent visits to the flowers, but the species is capable of over 50 % seed capsule production. Geitonogamy is the transfer of self pollen between flowers on the same individual. It is typical that the pollinators of deceptive inflorescences visit only few flowers and have short stays in them, and therefore it is commonly thought that geitonogamy is infrequent among deceptive species. I examined the role of geitonogamy in the seed production of D. maculata. I prevented geitonogamy in male-sterilizati…
