Rapid disruption of pollination function by the invasive plant Impatiens glandulifera
Plant Biology, Volume 28, Issue 5, Page 1481-1490, August 2026.Invasion by Impatiens glandulifera rapidly disrupts pollination of the native plant Stachys sylvatica by altering pollen transport by shared bumblebee pollinators. A short‐term field introduction revealed a dramatic decline in conspecific pollen deposition within 4 days, showing that pollination function can collapse quickly following invasion, even ...

Protoplasma, 2017 We investigated the morphology and structure of the floral nectary in 11 Neotropical genera belonging to the subfamilies Dodonaeoideae and Paullinioideae (Sapindaceae) from southern South America representing three tribes (Dodonaeaeae, Paullinieae, and Melicocceae), in relation to other floral traits in species with contrasting morphological flower ...

CRABS CLAW Acts as a Bifunctional Transcription Factor in Flower Development
Frontiers in Plant Science, 2018 One of the crucial steps in the life cycle of angiosperms is the development of carpels. They are the most complex plant organs, harbor the seeds, and, after fertilization, develop into fruits and are thus an important ecological and economic trait ...

Plant Biology, Volume 28, Issue 5, Page 1454-1466, August 2026.Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

The flower morphology in three Convallariaceae species with various attractive traits
Acta Agrobotanica, 2017 The general morphology and micromorphology of the flower in Polygonatum multiflorum, Maianthemum bifolium, and Convallaria majalis were studied using light microscopy methods. Among the studied species, P. multiflorum and C.

Ultrastructure and Function of Floral Nectaries ofChamelaucium uncinatum(Myrtaceae) [PDF]
Annals of Botany, 1996 Abstract Nectar is secreted for up to 11d after anthesis inChamelaucium uncinatum. The volume and sucrose concentration secreted varies between flowers, plants and days. The period of nectar secretion coincides with the period of pollen presentation and stigmatic receptivity suggesting nectar is part of an efficient reproductive strategy inC ...

Acta Botânica Brasílica, 2018 Nectar production has an important role in pollinator attraction and successful fruit production in many self-incompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics.
