摘要

We examined Aristolochia bracteolata, Lam belonging to family Aristolochiaceae-for mycorrhizal association from six different sites of Shirur Taluka, District Pune. Aristolochia is non-mycorrhizal plant. The maximum number of AM propagules (226 per 100 g of soil) was reported in July from Alegaon locality and minimum (21 per 100 g of soil) were reported in October from Nagargaon. The highest root infection (85 %) was reported in August from Nhavare locality and lowest root infection (10 %) was reported in October from all the live localities except Malwadi. Five genera with ten species were isolated from rhizosphere soil of Aristolochia bracteolata, Lam. The genus Glomus was dominant with six species. The other genera reported were Acaulospora, Sclerocystis, Gigaspora and Scutellispora with one species each.
