Flowers, leaves or both? How to obtain suitable images for automated plant identification [PDF]

open access: yes, 2019
Background: Deep learning algorithms for automated plant identification need large quantities of precisely labelled images in order to produce reliable classification results. Here, we explore what kind of perspectives and their combinations contain more

Alkyl resorcinols in grains from plants from the family Gramineae

open access: yesActa Societatis Botanicorum Poloniae, 2014
5-n-alkylresorcinols were found in 22 of the 27 studied species of grasses. In Agropyron caninum and Bromus macrostachys only the content of alkyl resorcinols was determined, in Agropyron repens, Bromus mollis and Elymus arenarius the composition of ...

Lack of Host Specialization on Winter Annual Grasses in the Fungal Seed Bank Pathogen Pyrenophora semeniperda. [PDF]

open access: yesPLoS ONE, 2016
Generalist plant pathogens may have wide host ranges, but many exhibit varying degrees of host specialization, with multiple pathogen races that have narrower host ranges. These races are often genetically distinct, with each race causing highest disease

The First Cases of Evolving Glyphosate Resistance in UK Poverty Brome (Bromus sterilis) Populations

open access: yesWeed science, 2018
Poverty brome (Bromus sterilis L.) [sterile or barren brome, syn. Anisantha sterilis (L.) Nevski] is a problematic UK arable weed. There are currently no confirmed cases of glyphosate resistance in any weed species in the United Kingdom or in B. sterilis

Pyroxasulfone is Effective for Management of Bromus spp. in Winter Wheat in Western Canada

open access: yesWeed technology, 2018
In response to concerns about acetolactate synthase (ALS) inhibitor–resistant weeds in wheat production systems, we explored the efficacy of managing Bromus spp., downy and Japanese bromes, in a winter wheat system using alternative herbicide treatments ...

Native and invasive inoculation sources modify fungal community assembly and biomass production of a chaparral shrub [PDF]

open access: yes, 2020
Feedbacks between plants and surrounding soil microbes can contribute to the establishment and persistence of invasive annual grasses as well as limit the success of restoration efforts.

Solar farms can mitigate negative impacts of whiplash weather on plant communities in a dryland ecosystem

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Utility‐scale solar energy (USSE) development generates novel questions regarding coupling clean energy production with terrestrial ecosystem services (e.g., forage production, pollinator support). We found that a USSE array sited in a fallowed cropland maintained a reseeded native plant community even a decade post‐restoration and that the array ...

Chromosomes of Bromus auleticus Trin. ex Nees (Poaceae)

open access: yesGenetics and Molecular Biology, 2003
The chromosome number of 14 accessions of Bromus auleticus Trin. ex Nees, native of Rio Grande do Sul, was 2n = 6x = 42, same ploidy level found in other South-American Bromus species.
