摘  要:
通过室内培养皿法,研究了银胶菊花朵水浸提液对泽漆、马唐、玉米、萝卜种子萌发和幼苗生长的化感作用。结果表明,银胶菊花朵水浸提液抑制受体植物种子萌发和幼苗生长,且相同浓度处理时,对受体植物根长生长的抑制作用高于对芽长、鲜重的抑制作用。4种受体植物中,水浸提液对马唐种子萌发的影响最大,在5%、10%处理浓度下完全抑制其种子萌发,在3.3%浓度下马唐种子萌发率仅为11.7%;对泽漆幼苗生长的影响最大,在5%、10%浓度下完全抑制其幼苗生长。

摘  要:
Experiments were conducted to determine the allelopathy of flower from Parthenium hysterophorus L.on seed germination and seedling growth of Euphorbia helioscopia L.,Digitaria sanguinalis(Linn.) Scop.,Zea mays L.and Raphanus sativus L..The results showed that aqueous extract exhibited strongly inhibitory effects on treated plants,and roots of treated plants were inhibited more strongly than shoots and fresh weight at the same concentrations.Aqueous extract exhibited more inhibitory effect on germination of D.sanguinalis than other plants,and the germination of D.sanguinalis were complete failure at 5% and 10% while 11.7% for D.sanguinalis at 3.3% .Aqueous extract exhibited more inhibitory effect on seedling growth of E.helioscopia than other plants,and the seedling growth of E.helioscopia were complete failure at 5% and 10% .
