采用室内生物测试法，研究白玉兰（ Magnolia denudate）、枫杨（ Pterocarla stenoptera）、红叶李（ Prunus cerasifera）、琼花（Viburnum macrocephalum）、紫丁香（Syringa oblata ）及重阳木（Bischofia polycarpa）6种园林树种叶片不同浓度水浸液对小麦（Triticum aestivum）、萝卜（Raphanus sativus）和小白菜（Brassica chinensis）3种作物萌发和生长的化感作用。结果表明：6种园林树种对3种作物均具有较强的化感抑制作用，且对幼苗生长的影响明显高于种子萌发。在水浸液0.0125 g· mL-1时，6种植物水浸液基本都显著或极显著地抑制了3种作物的根长和苗高，在浓度为0.1 g· mL-1下，几乎完全抑制了3种作物根和幼苗的生长。6种植物的综合效应在30％～80％，综合效应强弱依次为紫丁香＞琼花＞重阳木＞白玉兰＞枫杨＞红叶李，表明6种植物具有较大的开发潜力。

The allelopathy of aqueous extracts of Magnolia denudate,Pterocarla stenoptera,Prunus cerasifera,Vibur-num macrocephalum,Syringa oblata,Bischofia polycarpa on seed germination and seedling growth of Triticum aesti-vum,Raphanus sativus and Brassica chinensis were studied indoors using a biological monitoring method .Results indi-cated that the six garden trees all exhibited strong allelopathic inhibition on crops .And, the allelopathic inhibition on seedling growth was greater than on seed germination .The six garden tree species significantly inhibited root length and seedling height of the three crops under the treatment of 0.0125 g· mL-1 extracts,and the root length and seed-ling height were fully inhibited under 0.1 g· mL-1 extracts.Synthesize effects of the six garden tree species were be-tween 30%~80%.Overall allelopathy of the six garden tree species decreased in the order of Syringa oblata>Vi-burnum macrocephalum >Bischofia polycarpa >Magnolia denudate >Pterocarla stenoptera >Prunus cerasifera. These results indicated great development potential of the six garden tree species .
