| Abstract | | German | German Rundblättrige Glockenblume; Honigbiene. Die melittophilen (bienenblütigen) Pflanzen werden von hummel- bis kleinbienengroßen Hymenopteren bestäubt. Honigbienen saugen Nektar aus der Saftkammer der Glockenblumen. Dabei berühren sie ventral den zunächst als Pollenträger, im späteren Stadium als Empfängnisorgan dienenden Endabschnitt des Griffels. | | English | English Structure and pollination of a bell-shaped bee-flower are shown by the example of the Harebell, Campanula rotundifolia. The visitors - honey-bees - suck nectar from the protected epigynous chamber on the flower bottom. Hereby they touch ventrally the style which is immature at the first stage of the protandrous flower, serving as a pollen discharger; during the female stage the stigma is exposed in the same position. The process of development of both phases is presented by quick-motion pictures. |
