Ungewöhnliche Pollenform bei Peucedanum venetum | Ungewöhnliche Pollenform bei Peucedanum venetum<br> | ||
Uncommon pollen morphology observed in Peucedanum venetum (Apiaceae). Peucedanum venetum belongs to the family of the Apiaceae. This family shows a very characteristic rod-shaped (prolate) pollen with three germination openings (tricolporate). In polar view the shape of this pollen is slightly triangular. In pollen samples of this species pollen very different from the basic form of the Apiaceae was found. These | |||
samples were prolate also but showed only two germination openings (dicolporate). In polar view the outline was elliptic with distinct constrictions on the two longer sides. This deviation of the usual pollen form might be triggered by local mutations or by disturbances during pollen development. | |||
