摘　　要：在广东、广西及海南３省区收集不同气候及立地条件下的４个藤种共２２个藤根及土壤样品，经镜检及湿筛分析结果表明，１１个藤根样品中有１０个具ＶＡ菌根，菌根感染率达８．３０％～４３．８％；在１１个土壤样品中，全部具ＶＡ菌根菌；其ＶＡ菌根菌种类达１３种之多，分别隶属无柄囊霉属、球囊霉属、硬囊霉属和盾巨孢囊霉属共４个属；其中，粗柄硬囊霉和小果硬囊霉为我国新分布种；此外，还有４个未发表种，分属于球囊霉属和盾巨孢囊霉属两个属中。广泛感染棕桐藤的ＶＡ菌根真菌有球囊霉属未发表种１号、粗柄硬囊霉和密色无梗囊霉。rattan species,22 rattan roots and their soil samples have been investigated and collected from different climate zones and site condition in Guangxi,Guangdong and Hainan Province. The results show that 10 VA Mycorrhizal fungi exist in among the 11 sam-ples of rattan roots with infective rate of 8.3%～43.O%;But VAM fungi spores exist in all 11 soil samples.13 species of VAM fungi have been identified.They belong to Glomus andScutellospora,Acaulospora and Scerocystis respectively.Four newly reported VAM species belong to Glomus and Scutellospora. Glomus sp.No.1,Sclerocystis pachycaulis andAcaulospora mellea are common species in rhyzosphere of rattan.
