Perfect flowers are protandrous, hence the stigmas open after anthesis, which reduces the probability of autogamous self-pollination. |
|
The flowers are resupinate, protandrous and last for 2 days. |
|
The flowers are protandrous, and larger plants have a lower pollen to ovule ratio than smaller plants, suggesting larger plants invest proportionally more in female function. |
|
It is a wind-pollinated species, with hermaphroditic protandrous flowers. |

Proximate control and adaptive potential of protandrous migration in birds. |

The mode of reproduction for whelks also needs investigation because Castagna and Kraeuter suggested that knobbed whelk may be protandrous hermaphrodites. |
