Occurrence of arbuscular mycorrhizal fungi in different cropping systems at Cochabamba, Bolivia (Research Note)	1999	11	.pdf	application/pdf	5248	323	64	Key words: AMF spore densities, arbuscular mycorrhizal fungi, cropping systems, diversity index, Glomales Introduction Arbuscular mycorrhizal fungi (AMF) are amongst the most commonly occurring soil fun- gi (Gerdemann 1968) and are associated with about 80% of terrestrial plants in most vegeta- tion types (Gianinazzi and Gianinazzi-Pearson 1986). The mycorrhizal diversity measured with the Shannon- Wiener index did however not differ very much between cropping systems.	cache/afs-5630.pdf	txt/afs-5630.txt
