The Mechanism of Polyembryonic Seed Set in Paspalum notatum.

CYTOLOGIA, 2001
Four facultatively apomictic varieties of bahia grass (Paspalum notatum Flugge) were studied for making it clear the mechanism of multiple embryo seed set development in polyembryonic ovules. Over 300 ovaries at and after anthesis were collected from each variety, treated with Herr's clearing fluid and observed with Nomarski differential interference ...

Winter cover crop integration on soil nitrogen loss from a subtropical warm‐season pasture field and its potential mitigation

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Bermudagrass is a summer forage crop with high nitrogen (N) demand. Introducing winter cover crops may sustain bermudagrass yields with less fertilizer, reducing environmental N losses. Field trials and lab incubation were carried out to evaluate the effects of white clover (Trifolium repens L.) and ryegrass (Lolium multiflorum) as winter ...

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Alternative approaches to turf systems: A review of pollinator‐friendly lawns

Crop Science, Volume 65, Issue 4, July/August 2025.
Abstract The global decline of pollinators, driven primarily by habitat loss due to urbanization and agricultural expansion, poses significant risks to biodiversity and food security. Turfgrass lawns, which dominate urban and suburban landscapes, offer a largely untapped opportunity to mitigate these declines by adopting pollinator‐friendly management ...

The Carbon Budget of Land Conversion: Sugarcane Expansion and Implications for a Sustainable Bioenergy Landscape in Southeastern United States

GCB Bioenergy, Volume 17, Issue 7, July 2025.
Sugarcane is poised to become a key bioenergy crop in the Southeastern United States, where its expansion may replace pasturelands. Our findings show that such land‐use transitions may incur significant carbon losses—beyond harvest or fire removals—led by rapid mineralization of legacy biomass and soil carbon upon conversion.
