Low pyrrolizidine alkaloid levels in perennial ryegrass is associated with the absence of a homospermidine synthase gene

BMC Plant Biology, 2018
Background Pyrrolizidine alkaloids (PAs) are a class of secondary metabolites that function as feeding deterrents in a range of different plant species.

Enhancing spring green‐up of warm‐season turfgrasses through late‐winter scalping

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Rapid spring green‐up of warm‐season turfgrasses in the transition zone is often desired to improve early‐season turfgrass quality, thereby increasing the acceptance of these species in arid and semi‐arid climates. This study evaluated the effects of late winter scalping on spring green‐up speed in 41 cultivars of bermudagrass (Cynodon spp ...

An evaluation of tall fescue (Lolium arundinaceum) as an alternative to perennial ryegrass (Lolium perenne) for use on dairy farms in the Waikato [PDF]

, 2011
Grazed pasture provides the bulk of feed on New Zealand dairy farms. As such, the amount, and the nutritive value, of the pasture grown directly influences farm production and profitability.

NTEP Perennial Ryegrass Study [PDF]

, 2017
The National Turfgrass Evaluation Program (NTEP) conducts trials throughout the United States on turfgrass adaptation. This trial was established in September 2016 as part of the NTEP program. It contains 114 perennial ryegrass cultivars.

Planting date effect on cool‐season grasses herbage accumulation in north Florida

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cool‐season annual grasses are important components of Florida forage systems, providing high‐quality forage when warm‐season perennial grasses are dormant. Strategies such as using alternative species and adjusting planting dates may extend the grazing season, improve resilience to weather variability, and increase producer profitability.

The Efficacy of Management Interventions to Restore Perennial Ryegrass Tiller Populations, Content and Production in Dairy Pasture

New Zealand Journal of Agricultural Research, Volume 69, Issue 6, December 2026.
Three interventions aimed at restoring perennial ryegrass populations and the herbage production of run‐out dairy pastures based on mid‐season or late‐season heading perennial ryegrass cultivars were compared with a control (CON) treatment over 3 years in Waikato. The treatments were: short deferral of grazing (47–48 days) in spring (SD); long deferral

The Fungus Aspergillus aculeatus Enhances Salt-Stress Tolerance, Metabolite Accumulation, and Improves Forage Quality in Perennial Ryegrass

Frontiers in Microbiology, 2017
Perennial ryegrass (Lolium perenne) is an important forage grass with high yield and superior quality in temperate regions which is widely used in parks, sport field, and other places. However, perennial ryegrass is moderately tolerant to salinity stress

UAV‐based RGB and multispectral vegetation indices as alternatives to light box‐derived dark green color index for turfgrass color assessment

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Traditionally, turfgrass color has been assessed through visual ratings or light box‐based digital image analysis, methods that are either subjective or labor‐intensive. In this study, we evaluated the potential of unmanned aerial vehicle (UAV)‐based multispectral and red‐green‐blue (RGB) imagery as a high‐throughput alternative for capturing ...

Influence of Epichloë on the Microbiota of Established Lolium perenne Pastures in Aotearoa, New Zealand

Phytobiomes Journal
Perennial ryegrass (Lolium perenne) is a critical species supporting New Zealand's intensive pasture-based agricultural industries. Perennial ryegrass forms a symbiotic, mutualistic association with asexual Epichloë, an endophytic fungus known to ...

Weed Detection in Perennial Ryegrass With Deep Learning Convolutional Neural Network

Frontiers in Plant Science, 2019
Precision herbicide application can substantially reduce herbicide input and weed control cost in turfgrass management systems. Intelligent spot-spraying system predominantly relies on machine vision-based detectors for autonomous weed control.
