Allelopathy of Equisetum arvense extract on seed germination and seedling growth of wheat
摘要
Abstract
The effect of Equisetumarvense root extract at different concentrations on seed germination and seed-ling 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)reduc-tions in seed germination rates of the 5 species of wheat with aqueous extracts of 70 and 100 mg/mL.The seed-ling 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 perox-idase (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 malondialde-hyde (MDA)content significantly (P<0.05)increased in wheat seedlings of GLN with the 70 mg/mL treat-ment 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.关键词
