| 摘 要： | 外来植物入侵对土壤微生物群落的影响一直受到关注.本文研究了外来植物加拿大一枝黄花(Solidago candensis L.)的人侵对本地丛枝菌根真菌(AMF)的影响,发现加拿大一枝黄花的入侵改变了本地植物群落物种组成,本地植物如鸡眼草(Kummerowia striata(Thunb.)Schindl.)和黑麦草(Loliumperertrte L)的菌根侵染率降低.与本地优势植物鸡眼草共生菌的种类发生变化,土壤AMF孢子密度明显降低.土壤由以摩酉球囊菌(Glomus mosseoe)和幼套球囊菌(Glomus etunic atum)为优势转为以地球囊菌(Glomus geosperum)和幼套球囊菌(Glomus etunic atum)为优势种.

| Abstract: | Whether and how plant invasion affecting on soil biological community has been greatly concerned recently.The effects of invasive species Solidago candensis L.on local arbuscular mycorrhizal fungi were examined in this study.Due to S.candensis invasion the local plant composition was changed greatly.S.candensis invasion reduced mycorrhizal fungal colonization rate of native plants K.striata and L.perenne.Compared to in the no invasion plant community,mycorrhizal fungi species in roots of the native plant K.... |
