Pollen From Western Australia At A Glance, Rob Manning
Bulletins 4000 -
Western Australian pollen proteins are high compared to many other plant species. Banksia pollens are highest at greater than 30% followed by eucalypt and acacia, which range from 20-28%.
Nectar Secondary Compounds Affect Self-Pollen Transfer: Implications For Female And Male Reproduction, Rebecca E. Irwin, Lynn S. Adler
Nectar Secondary Compounds Affect Self-Pollen Transfer: Implications For Female And Male Reproduction, Rebecca E. Irwin, Lynn S. Adler
Dartmouth Scholarship
Pollen movement within and among plants affects inbreeding, plant fitness, and the spatial scale of genetic differentiation. Although a number of studies have assessed how plant and floral traits influence pollen movement via changes in pollinator behavior, few have explored how nectar chemical composition affects pollen transfer. As many as 55% of plants produce secondary compounds in their nectar, which is surprising given that nectar is typically thought to attract pollinators. We tested the hypothesis that nectar with secondary compounds may benefit plants by encouraging pollinators to leave plants after visiting only a few flowers, thus reducing self-pollen transfer. We …
The Structure And Ultra Structure Of Anther Epidermis And Pollen In Lagerstroemia Indica L. (Lythraceae) In Response To Air Pollution, Farkhondeh Rezanejad
The Structure And Ultra Structure Of Anther Epidermis And Pollen In Lagerstroemia Indica L. (Lythraceae) In Response To Air Pollution, Farkhondeh Rezanejad
Turkish Journal of Botany
The structure of the anthers and pollen of Lagerstroemia indica L. (crepe myrtles) (Lythraceae) in samples collected from clean and polluted areas was studied by OM, SEM, and TEM. The epidermal cells of the anthers enlarged during anther development. Their cuticle content increased and became thick and folded. The cytoplasm of epidermal cells was peripheral and degenerated in mature anthers. At this time, their major content was phenolic compounds. The epidermal cells in the anthers collected from polluted areas were shrunken, fragile, and burned at the tip, compared to those collected from non-polluted areas. Flavonoid stainability was greater in the …

The Effects Of Feeding Pollen Cake Containing Royal Jelly On Bombus Terrestris L. (Hymenoptera: Apidae) Colony Development, Fehmi̇ Gürel, Ayhan Gösteri̇t
Turkish Journal of Veterinary & Animal Sciences
This study was performed to determine the effects of feeding pollen cake containing honeybee royal jelly on Bombus terrestris colony development. In total, 125 bumblebee queens, 68 of which were fed pollen cake containing 10% royal jelly and 57 of which were fed normal pollen cake, were used. We found that 84% of the queens fed pollen cake containing royal jelly and 82% of those fed normal pollen cake laid eggs; 56% of the queens fed normal pollen cake established colonies, whereas queens fed pollen cake containing royal jelly did not establish any colonies and their larvae died. The results …
