Inundation Duration Shapes Germination of Native and Non‐Native Plant Assemblages From Floodplain Soil Seedbanks

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Episodic inundation regulates germination and recruitment from soil seedbanks, which are key processes driving vegetation dynamics in dryland floodplains. In the Murray‐Darling Basin, extensive floodplain modification and flow regulation have altered flow regimes so that anthropogenically controlled environmental watering is often required to ...

Silicon Nanoparticles Enhance Cold Tolerance in Elymus nutans Seedlings by Regulating Growth, Physiology, and Gene Expression Under Cold Stress

open access: yesFood and Energy Security, Volume 15, Issue 2, March/April 2026.
ABSTRACT Cold stress represents one of the primary abiotic stresses affecting forage growth, development, yield, and quality. As a novel agricultural nanomaterial, silicon nanoparticles (SiNPs) demonstrate unique potential in regulating plant stress responses. However, their mechanism of action in forage cold responses remains poorly understood.

Independent Review of Direct Seeding Techniques to Restore Grassy Woodland: Five Case Studies on the Cumberland Plain

open access: yesEcological Management &Restoration, Volume 27, Issue 1, January 2026.
ABSTRACT This study investigates the effectiveness of several direct seeding techniques in the restoration of Cumberland Plain Woodland, with a focus on understanding the influence of environmental variables and seeding techniques on outcomes. A series of direct seeding trials were conducted across nine sites previously dominated by exotic grasses on ...

Cytogenetic studies in the Eragrostis curvula Complex

open access: yesBothalia: African Biodiversity & Conservation, 1977
Cytogenetic studies were undertaken in the  Eragrostis curvula Complex. Three plants were studied at each of 16 collecting points. The overall morphology and embryo sac development of all plants were evaluated, while the chromosome number and ...

Imaging of Molecular and Developmental Responses to Abiotic Stresses in Reproductive Tissues

open access: yesPhysiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stresses, such as drought, salinity, and extreme temperatures, have profound effects on plant reproduction, often leading to reduced fertility and yield. Reproduction in plants involves complex interactions between diverse cells, necessitating spatiotemporal resolution to understand how stress impacts each component of this intricate ...
