通过培养皿法和盆栽法对巨桉（Eucalyptus grandis Hill ex Maiden）、邓恩桉（Eucalyptus dunnii Maiden）的浸出溶液的化感作用进行了研究。研究结果表明，其对玉米（Zea mays）、小麦（Triticum aestivum），萝卜（Raphanus sativus）、绿豆（Vigna radiata）四种农作物的发芽指数和发芽率都有不同程度的抑制作用，但对幼苗生长的抑制作用不太明显；同时，还对土壤种子库中的杂草种子萌发有明显的抑制作用。这说明化感作用是这两种桉树的林下很少有其他植物，容易造成水土流失的原因之一。

The wuthors analyzed the allelopathy of the leaching liquor of Eucalyptus grandis Hill ex Maiden and Eucalyptus dunnii Maiden by the culture dish method and pot-culture method. According to the research,it is found that the Allelopathy restrict in a certain degree the pullulation index and pullulation rate of Zea mays, Triticum aestivum,Raphanus sativus and Vigna radiata,while the restriction effect doesn’t evident for the growing of young seeding. Meanwhile,the allelopathy keeps down the sprouting why of weed seeds in soil seed bank. So the allelopathy is one of the reasons that there are few other plants living under these two eucalyptus where mudslide happens frequently.
