title: Colonization and diversity of AM fungi by morphological analysis on medicinal plants in southeast China.
abstract: The arbuscular mycorrhizal (AM) fungal distributions in the rhizosphere of 20 medicinal plants species in Zhangzhou, southeast China, were studied. The results showed 66 species of 8 genera of AM fungi were identified, of which 38 belonged to Glomus, 12 to Acaulospora, 9 to Scutellospora, 2 to Gigaspora, 2 to Funneliformis, 1 to Septoglomus, 1 to Rhizophagus, and 1 to Archaeospora. Glomus was the dominant genera and G. melanosporum, Acaulospora scrobiculata, G. etunicatum, Funneliformis mosseae, and G. rubiforme were the prevalent species. The highest colonization (100%) was recorded in Desmodium pulchellum (L.) Benth. while the lowest (8.0%) was in Acorus tatarinowii Schott. The AM fungi spore density ranged from 270 to 2860 per 100 g soil (average 1005), and the species richness ranged from 3 to 14 (average 9.7) per soil sample. Shannon-Wiener index ranged from 0.52 to 2 (average 1.45). In the present study, the colonization had a highly negative correlation with available K and electrical conductivity. Species richness correlated positively with electrical conductivity and organic matter. Shannon-Wiener index had a highly significant negative correlation with pH. This study provides a valuable germplasm and theoretical basis for AM fungal biotechnology on medicinal standardization planting.
