| 摘 要： | 通过对鄂尔多斯高原毛乌素沙地油蒿（Ａｒｔｅｍｉｓｉａ ｏｒｄｏｓｉｃａ）化感作用研究，发现油蒿茎叶的水浸提液对几种受体植物种子的萌发率，幼苗长和根长生长均有不同程度的抑制作用，随水浸提液浓度的增加抑制作用逐步增加；用油蒿茎叶水浸提液进行盆栽试验，受体植物的出苗率，苗高，根长和干物重也受到抑制，苗的形态也与对照有较明显的差异；

| Abstract: | The allelopathic effects of Artemisia ordosica on receptor plant species: Amaranthus tricolor,Orychopragmus violaceus,Raphanus sativus and Triticum aestivum was gaven.The aqueous extracted from aerial parts of A.ordosica causes inhibition on germination and decreases seedling and root elongation of receptor plants in vitro.The dry weight,seeding height and root length are reduced proportionally at various concentrations of the extracts.In different organic extracts of aqueous extracts,EtOAc extracts significantly inhibited the seedling and root elongation of receptor plants.This EtOAc extracts is separated into three parts.Through identification with chemical reactions,it was found that the bioactive fraction contained flavonoid compounds. |
