An Entity of Type: place, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A pollen-presenter is an area on the tip of the style in flowers of plants of the family Proteaceae on which the anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination.

  • A pollen-presenter is an area on the tip of the style in flowers of plants of the family Proteaceae on which the anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination. (en)
  • Un présentoir à pollen est une zone située à l'extrémité du style chez les fleurs des plantes de la famille des Proteaceae. Dans cette famille, les anthères sont difficiles d'accès pour les pollinisateurs potentiels, tels que les abeilles, les oiseaux et les mammifères nectarivores. Pour assurer la pollinisation, les anthères libèrent leur pollen sur les présentoirs à pollen avant l'anthèse. Après l'anthèse, le style sort nettement du périanthe, assurant la distribution du pollen. Le dépôt systématique du pollen sur le bout du style signifie que les plantes doivent avoir une stratégie pour éviter une auto-pollinisation excessive. (fr)
  • Un presentatore di polline è un'area sulla punta del pistillo nei fiori delle piante della famiglia Proteaceae. In questa famiglia, le antere sono di difficile accesso ai potenziali vettori di impollinazione, quali le api, gli uccelli e i mammiferi nettarivori. Per assicurare l'impollinazione, le antere rilasciano il loro polline sul presentatore di polline prima dell'antesi. Dopo l'antesi, lo stilo si allunga esternamente in maniera prominente, assicurando la distribuzione del polline. Il deposito sistematico del polline sulla punta dello stilo indica che le piante debbano avere delle strategie per evitare un eccesso di autoimpollinazione. (it)
