Effect of land use type on arbuscular mycorrhizal fungi diversity in high altitude of Karo Highland

Abstract

This study evaluated the spore density and diversity of arbuscular mycorrhizal fungi (AMF) in different land use type at Karo Highland. Sampling of soil AMF was conducted once as a material for trap culture by using Pueraria javanica as a host. The trap culture was used to observe the spore density and percentage of root colonization. The results showed that spore density and AMF colonization was not affected by different land use type, but rather by soil chemical properties. Soil acidity and phosphorus content had negative effect on root abundance and colonization, while carbon, nitrogen and potassium content gave positive effects. This study found 15 AMF spores from all types of land use dominated by Glomaceae followed by Acaulosporaceae and Gigasporaceae. The occurrence of AMF species was not specific to one type of land use but rather evenly dispersed in all types.
