Název v původním jazyce

Protandry promotes male pollination success in a moth-pollinated orchid

Popis výsledku v původním jazyce

1. Temporal separation of male and female phases in hermaphrodite flowers (dichogamy) is proposed to reduce self-pollination, both within and among flowers. Darwin and later workers suggested that protandry (the most common form of dichogamy, in which the male phase precedes the female phase) should be most effective in reducing geitonogamous (between-flower) self-pollination when pollinators forage upwards from older female-phase flowers to younger male-phase flowers on vertical inflorescences. 2. We tested this hypothesis by manipulating the extent of protandry in artificial inflorescences of the orchid Satyrium longicauda Lindl. and using stained pollen to quantify self-pollination and pollen export. 3. Upper flowers of non-protandrous inflorescences received more self-pollen through geitonogamy than lower flowers, unlike protandrous inflorescences. Protandry reduced absolute levels of self-pollination, as the amount of removed pollen involved in selfpollination was three times grea
