摘要
对贵州省荔波县茂兰国家自然保护区圆叶乌桕(Sapium rotundifolium Hemsl)的丛枝菌根(Arbus-cular mycorrhizal,AM)真菌进行了初步分离、鉴定与多样性分析。结果表明,乌桕根系的菌根侵染率为44.3%;从乌桕根系土壤中分离到AM真菌2个属29种,分别为球囊霉属(Glomus)21种、无梗囊霉属(Acaulospora)8种。其中,球囊霉属(Glomus)为优势属,枫香球囊霉(G.liquidambari)和凹坑无梗囊霉(A.excavatadun)为优势种。
Arbuscular mycorrhizal fungi in Sapium rotundifolium Hemsl.in Maolan National Nature Reserve of Libo in Guizhou province was isolated and identified to study their diversity.The result showed that the root colonization rate of S.rotundifolium was 44.3%.29 species in 2 genera（21 Glomus species and 8 Acaulospora species） were identified from the rhizospheres soil of S.rotundifolium.Glomus was the dominant genus;while G.liquidambari and A.excavatadun were dominant species.
