Przykłady anther

• We found strong positive correlations between anther height and corollatube length in both morphs.

• Strong positive correlations (r > 0.9) between anther height and corolla-tube length were found in both morphs.

• For anther height, and anther length, we measured the mean value for three anthers in each flower.

• A plant was considered as having reached anthesis or silking if at least one extruded anther or one silk was visible.

• Before being released from the anther, the pollen grain usually becomes desiccated and enters in a phase of stasis.

• The insects touched stigmas and anthers when collecting pollen and nectar.

• The electron-dense inclusions in the outer layer of the intine of pollen at the open anther stage are probably remnants of the degraded cytoplasmic channels.

• The stamens have a rigid filament and a length that places the anthers beyond the tube of the corolla precisely under its upper lip.

• The stigma extends beyond the anthers by a couple of millimetres allowing both hummingbird groups to deposit pollen.

• Flowers were emasculated by removing the anthers before anthesis in the early evening.

• The pollen sacs are confused with anthers and the term ' petiole ' is used for flower stalk which should be ' pedicel'.

• They almost always contacted the stigma and anthers, and were classified as pollinators.

• Corolla-tube length (a), anther height (b), stigma height (c), corolla-lobe length (d), stigma-lobe length (e), and anther length (f) were measured.

• In order to collect pollen, adults scrape anthers with the proboscis and gather the grains.

• This floral structure may act as a developmental constraint and generate positive anther- corolla correlations.
