False‐green kyllinga competitiveness from seed in turfgrass

open access: yesCrop Science, Volume 65, Issue 5, September/October 2025.
Abstract False‐green kyllinga (FGK; Kyllinga gracillima Miq.) is a warm‐season perennial weed in the Cyperaceae family. Our objective was to determine the potential for FGK to establish from seed in turfgrass. Replicated field experiments were conducted in Kentucky bluegrass (Poa pratensis L.) mowed at 6 cm.

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

open access: yesNordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Breaking the norm: Absence of seed size/seed number trade‐off in Hymanaea stigonocarpa, a tree species from the Brazilian semi‐arid

open access: yesPlant Species Biology, Volume 40, Issue 5, Page 472-482, September 2025.
Seed size/number trade‐off is a central topic in plant biology as it reflects ecological and evolutionary aspects of the species. Here we report the absence of a trade‐off mass/number of seeds and fruits in a polyspermic plant probably associated to abortion of self‐pollinated pistils and flowers.
