Abstract. Pedicularis kansuensis is a dominating poisonous weed, and it might have allelopathic effects on other native grasses in alpine meadows. An experiment was conducted to examine a range of concentrations of aqueous whole plant extracts (25, 12.5, 2.5, 1.25, 0.25 and 0.0 g/L) of P. kansuensis, prepared at the flowering stage on seed germination and seedling growth of two native grasses (Poa pratensis and Elymus nutans). High concentrations of aqueous extracts of P. kansuensis inhibited seed germination and seedling growth of P. pratensis (p< 0.05). Most aqueous extracts of P. kansuensis had a stimulatory (p< 0.05) effect on E. nutans. Our results suggest that the allelopathic ecology of P. kansuensis on other native grasses needs further experiments.
