Self-Incompatibility |
Prevents or deter self-pollination Genetic self-recognition Temporal mismatching Physical barriers |
|
|
Temporal Mismatching |
Dichogamous: Male/female functions @ different times Protandrous: Male parts first Protogynous: Female parts first |
|
|
Physiological Mechanisms |
Gametophytic: Gametophyte prevents fertilization, pollen tube recognized and rejected Sporophytic: Sporophyte prevents fertilization, proteins recognized on the stigma. Pollen doesn't germinate |
|
|
Pollination by Abiotic Factors |
Anemophily- Wind pollinated
Hydrophily- Water pollinated |
|
|
Pollination by Biotic Factors |
Zoophily- Vertebrate pollinators Entomophily- Insect pollinators |
|
|
Attract Pollinators |
Nectar food rewards Pollen food rewards Resins, oils, scent, waxes Providing heat Being sexy Visual displays |
|
