Urban natives: Plants evolve to live in cities

Researchers found that a plant species adapted to urban conditions exhibited inheritable characteristics, such as changes in size and flowering periods, within 60 years of urbanization. Elevated ground temperatures and reduced soil acidity drove these differences.

Fungicides intended to suppress turfgrass diseases may damage fairways

Researchers evaluated nine commercially available demethylation inhibitor (DMI) fungicides on annual bluegrass and creeping bentgrass fairways. The study found that two fungicides caused injury to annual bluegrass but not creeping bentgrass, while another fungicide resulted in the lowest injury on both species.

Look to the data, not the marketing: Turfgrass research shows no differences in ‘penetrant’ and ‘retainer’ wetting agents

A multi-state study found inconsistent results on the performance of 'penetrants' and 'retainers,' emphasizing the importance of evidence-based surfactant classification. The research showed varying effects on rootzone volumetric water content and surface firmness, depending on location and turfgrass species.

On the origin (and fate) of plants that never bloom

A study by Kobe University reveals that plants reproducing solely through self-pollination likely arose from populations with extremely low genetic diversity. The research found that these species are highly successful at producing fruit and may have an evolutionary edge over outcrossing, raising questions about their long-term viability.
