Australian Research Finds Aspirin Improves Grass Seedling Survival

Researchers at Australia’s Curtin University are publishing a study in PLOS ONE that showed that aspirin, which naturally occurs in the bark of the willow tree and other plants, can improve the survival of grass species important for ecological restoration and sustainable pasture when applied in a seed coating. The study using native perennial grasses showed that very low concentrations of salicylic acid applied as a seed coating can improve plant survival and effectiveness in reaching restoration goals. Research team member Kingsley Dixon noted, “Further research is now needed to test salicylic acid as a coating in other wild species to improve native plant resistance to drought, extreme temperatures, salinity, pathogens, and herbicides.”
