Philosophical Transactions of the Royal Society B: Services on Demand Journal. None of these species produced fruits by the agamospermy tests, therefore indicating that they require the presence of pollen on the stigmas for fruit setting. Fruit set differed signifcantly depending on the origin of pollen as well as on the presence of a pollen vector.

Population improvement in alfalfa: The total number of plants corrresponded to nearly all plants growing at each study site 9 plants of G.

Contrasting breeding systems, foral displays, and fruit sets reported in this narrow-scaled study certainly encourage further investigations concerning reproductive strategies in orchids of southern South America.
