摘　　要：珍稀濒危植物绵刺与其所在群落中主要物种沙冬青、旱蒿、霸王、长叶红砂之间以及自身的他感作用研究结果表明:在5种植物的鲜枝叶水浸提液中,沙冬青、旱蒿对绵刺种子萌发有明显的抑制作用,对幼苗生长的影响主要表现在对幼根和幼芽伸长生长的抑制;霸王和长叶红砂对绵刺种子萌发的抑制作用不明显,而对绵刺幼苗生长的影响较大;同时绵刺对自身种子萌发产生自我中毒作用。The allelopathic effect of Ammopiptanthus mongolicus,Artemisia xerophytica,Zygophyllum xanthoxylon,Reaumuria trigyma and itself on rare and endangered plant Potaninia mongolica Maxim was studied.The results showed that water extract of A. mongolicus and A. xerophytica had significant inhibitory effects on seed germination of P. mongolica Maxim. the main influence on young sprout was to repress the growing of the root and bud. The water extract of Z. xanthoxylon and R. trigyma had little effects, even had promotion function, but had great influence on the primary growth. At the same time, P. mongolica Maxim. produced the ego poisoned function to the seed germination of itself.
