| 摘 要： | 以甘肃省栽培的重要药用植物黄芪、党参、黄芩和甘草为材料,研究其地上部分(茎、叶)和根不同浓度的水浸液对不同作物的种子萌发及幼苗生长的影响。结果表明:就4种受体植物而言,黄芪和党参的化感作用较强,而甘草和黄芩的化感作用较弱,其化感作用强弱依次为:黄芪>党参>甘草>黄芩;供试中草药不同部位的化感效应不同,地下部分的化感作用强于地上部分,其化感物质可以通过雨雾淋溶的途径进入环境作用于其他植物。

| Abstract: | The allelopathic effects of aqueous extract of roots and above-ground organs from Astrgalus membranaceus var. mongolicus (Bag) Hsiao, Glycyrrhiza uralensis Fisch, Scutellaria baicalensis Georgi and Codonopsis pilosula(Franch.) planted in Longxi of Gansu province on receiverplants' seed germination and seedling growth were sutdied. The result showed that A. membranaceus var. mongolicus and C. pilosula (Franch.) had stronger allelopathic potentiality, but their effects were not the same in different organs. The order of multiple effect was A. membranaceus var. mongolicus> C.pilosula > G. uralensis > S. baicalensisi. The allelopathy of roots was stronger than that of the above-ground organs, and rain eluviation was one of ways of allelochemicals releasing. |
