Abstract: The effect of Equisetum arvense root extract at different concentrations on seed germination and seedling growth of wheat was bioassayed to study the allelopathic dynamics of E. arvense to wheat and to provide a theoretical basis for wheat production. There were no significant effects on seed germination rates of 5 cultivars of wheat [Longmai 26 (LM26), Kenjiu10 (KJ10), Longmai 33 (LM33), Longfu18 (LF18) and Gelaini (GLN)] with aqueous extract (5 and 30 mg/mL) of E. arvense, but there were significant (P<0.05) reductions in seed germination rates of the 5 species of wheat with aqueous extracts of 70 and 100 mg/mL. The seedling heights of LM26 and LF18 decreased with 100 mg/mL treatment and seedling height of all species of wheat increased with other treatments. The dry matter weight of seedlings of the five species decreased and the peroxidase (POD) activity in wheat seedlings increased with the treatments. The water-soluble sugar (WSS) content was significantly (P<0.05) reduced in wheat seedlings of LM26, KJ10, LM33 and GLN. The malondialdehyde (MDA) content significantly (P<0.05) increased in wheat seedlings of GLN with the 70 mg/mL treatment and in LF18 with the 100 mg/mL treatment (P<0.05). The catalase (CAT) activity significantly (P<0.05) increased in wheat seedlings LM26,LF18,GLN with the treatment concentration increasing.
