Temperature-dependent germination dynamics of herbicide-resistant and susceptible blackgrass (Alopecurus myosuroides) and silky windgrass (Apera spica-venti) from Poland.

ABSTRACT: Herbicide-resistant grass weeds, including blackgrass (Alopecurus myosuroides Huds.) and silky windgrass (Apera spica‑venti (L.) P.Beauv), pose an escalating challenge to sustainable cereal production in Europe. This study examined temperature‑dependent germination dynamics of herbicide‑resistant (HR) and susceptible (S) biotypes of both species collected from Polish agroecosystems. Germination was tested under five temperatures: constant 5, 10, 15, and 20 °C, and alternating 15/5°C. Resistance groups were evaluated using the area under the germination curve (AUC), a cumulative measure that integrates both the speed and extent of germination. In both species, temperature strongly modulated germination dynamics. Multiple‑resistant blackgrass biotypes exhibited higher germination rates at ce
