Scientific and model organism use:
Poa annua is used as a model annual grass for genetics, weed ecology, and turfgrass management because its life cycle can be completed in 6–12 weeks under controlled conditions, allowing rapid generation turnover. It serves as a system for investigating the molecular basis of herbicide resistance; several studies have characterized resistance mechanisms in natural populations of Poa annua. Whole‑genome sequencing of Poa annua has produced a reference assembly that supports comparative genomics within Poaceae and gene discovery for stress tolerance and seed biology. The species is also employed in phenological research on flowering‑time responses to temperature and photoperiod, with datasets contributed to climate‑impact modeling platforms. Open‑access resources such as the Poaceae Genome Hub host transcriptomic data, genome assemblies, and marker sets for Poa annua, facilitating community research.

Properties relevant to use:
Poa annua has a short life cycle (6–12 weeks from germination to seed set), enabling quick experimental turnaround. It produces large numbers of seed (several thousand per plant under favorable conditions) and tolerates a variety of soil types, from sandy to loamy, making it suitable for greenhouse assays. The plant has a low chromosome number (2n = 14) that facilitates genetic studies. Its leaf tissue is relatively low in lignin compared to many perennial grasses, which aids extraction of nucleic acids and rapid digestibility assays. The broad temperature range for germination (approximately 5–25 °C) and the lack of a prolonged after‑ripening requirement further support its use in controlled experiments.

Standards and regulation:
Poa annua is included in seed‑testing protocols such as ASTM D7329 (Standard Test Method for Determination of Seed Germination) and the International Seed Testing Association (ISTA) Rules, where the species serves as a reference weed seed for germination assays. Herbicide‑screening experiments with Poa annua are conducted under national pesticide regulation frameworks (e.g., EPA guidelines in the United States and the EU Plant Protection Products Regulation) that govern the use of test organisms in efficacy trials.
