Smearing of pollen is facilitated by the fanning out of anthers borne at the ends of the filaments. |
|
The actinomorphic, tubular flowers of both species are pale blue to mauve, with epipetalous anthers. |
|
Within-flower transfer of pollen from anthers to stigma was achieved by depressing the keel petal of newly opened flowers using fine forceps. |
|
Flowers open wide in full sun, and with the central yellow anthers, the effect is striking. |
|
They eat exposed pollen on the anthers, while other pollen grains adhere to their legs. |
|
Fresh pollen was collected from anthers on plants by gently tapping the stems of plants while holding a collecting tray below the tassels. |
|
When taking nectar, hummingbirds contacted anthers, receiving pollen on their bill. |
|
For estimation of pollen production, two anthers from each flower bud were examined. |
|
There are usually about 20 stamens, with anthers that range from pink to burgundy in color. |
|
As the bee's proboscis is inserted into the flower it pushes past the retrorse anthers to the nectar at the base of the tube. |
|
Each flower has a lemma and a palea at its base, and contains two lodicules and one pistil surrounded by three anthers. |
|
Stamens are didynamous, but the yellow anthers occur close together, with their divergent thecae spreading to the outside. |
|
As pollinators removed pollen from the thecae, their walls collapsed and the anthers curled down gradually. |
|
The length and width of anthers were measured with a micrometer under a stereomicroscope. |
|
Among tremulous flora and fauna are tremandra plants, with their shaking anthers, the gelatinous tremella fungi, and treron pigeons. |
|
Pollen, in monads or tetrads, is presented in the anthers, adhering to the anther by means of pollenkitt or elastoviscin until collected. |
|
In self-pollination, the flower is monoclinous and the stigma receives pollen from the anthers of the same flower. |
|
These are the male part of the flower consisting of pollen-bearing anthers at the end of stalk-like filaments. |
|
I removed the anthers from a single flower on each marked branch before dehiscence and marked the base of the hypanthium with a spot of paint. |
|
Closed flowers were stripped of sepals, petals and anthers just prior to stigma maturity. |
|
|
In these flowers, the anthers are attached to the petals by short filaments half way down the corolla tube. |
|
The style is enclosed in a tube formed by the five fused anthers and filaments. |
|
Short and long stamens were measured from the base of the filament to the tip of the anthers. |
|
Disk florets have a tubular corolla with five small radially symmetrical lobes and five connate anthers forming a cylinder around the style. |
|
Five introrse anthers are united to form a cylinder around the style while the separate filaments are attached to the base of the corolla tubes. |
|
The ten stamens are introrse, and when elongate the anthers group in the upper part of the flower. |
|
Microspores were induced to enter the embryogenic pathway by pretreating whole anthers in mannitol salt solution. |
|
Cross-pollinated flowers were not emasculated, and pollinations were performed by rubbing anthers onto stigmas. |
|
Extrorse anthers are somewhat concentrated in primitive dicots and primitive monocots and are rare in more advanced groups. |
|
When the gynoecium did not abort, F1 flowers were protogynous with the stigma maturing prior to the anthers. |
|
Both species landed directly on the column but, while one scraped its abdomen against the anthers, the other introduced its glossa into the anther, and then scraped it. |
|
The genus is characterized by tetramerous flowers with bithecal anthers, lack of pseudostaminodia, a capitate or poorly defined stigma, and pollen of the Amaranthus type. |
|
Flowers are self-compatible, but spontaneous autogamy occurs very infrequently due to protandry and to the spatial separation of anthers and stigma. |
|
The anthers were dissected from the buds under a stereoscope. |
|
A freeze at this stage can kill or damage the pollen-producing anthers, affecting kernel development and possibly causing the plant to become sterile. |
|
After dissection, anthers remained in the wetting agent for another hour. |
|
The style, with a narrow bifid stigma, extends above the anthers by 5 mm. |
|
Total RNA was extracted from leaves, tillers, young panicles, leaf sheaths, hulls, and anthers of rice using the hot phenol method as previously described. |
|
The style projects from the corona of anthers and elongates with age. |
|
At the balloon stage of flowering, petals were peeled away and the swollen anthers were removed from the filaments by rubbing the open flower on wire mesh. |
|
|
Microspores and pollen grains are produced from pollen mother cells, PMCs within loculus anthers of the flower. |
|
Their flowers, appearing on the apical meristem, have the anthers fused along the edges, forming a column surrounding the pistil's style. |
|
When the tassel is mature and conditions are suitably warm and dry, anthers on the tassel dehisce and release pollen. |
|
Cytochemical and ultrastructural observations of anthers and pollen grains in Lathyrus undulatus Boiss. |
|
Likewise, the differing locular maturation in the anthers of the Plumerioideae and Apocynoideae could support paraphyly. |
|
All hamamelidaceous genera of the Southern Hemisphere are characterized by a unique feature of the anthers. |
|
Stamens number eight to twelve, are opposite the sepals and petals, and have introrse, dorsifixed anthers that dehisce by longitudinal slits. |
|
Eye-catching black willow, Salix gracilistyla 'Melanostachys', bears dark catkins with red anthers along vivid mahogany branches. |
|
Pollination is the transfer of pollen grains from the anthers to the stigmas to start the process of sexual reproduction. |
|
In Barnadesioideae, anthers that are auriculate or decurrent with the filament, such as those of Barnadesia, are very common. |
|
Ceiba speciosa flowers are relatively, pink colored and have staminal tube with sessile anthers, Table. |
|
Staminate catkins are 2-3 mm in diameter with tricolpate platanaceous pollen within elongate anthers. |
|
The staminodes range from diminute and filiform to very well developed with the appearance of sterile anthers, in some cases containing few pollen grains. |
|
The only exit leads to the anthers that deposit pollen on the visitor. |
|
This semi-evergreen shrub produces fragrant white flowers with yellow anthers from winter to early spring, and it should be grown against a wall so it will flower more freely. |
|
The corona is formed during floral development as a tubular outgrowth from stamens which fuse into a tubular structure, the anthers becoming reduced. |
|
Embryoid formation in anthers of some interspecific hybrids in Solanurn. |
|
Anthers were removed and placed among silica pellets in a glass jar and left to dry for 2-3 days at room temperature, which allowed the anthers to dehisce. |
