Characteristics and Abundance Spores of Arbuscular Mycorrhiza Fungi on Different Host Plants

Abstract

This research aimed to study the characteristics and abundance spores of local arbuscular mycorrhiza fungi (AMF) on different host plant. This research conducted in completely randomized block design (CRBD) with factorial pattern and each treatment was repeated three times and each consist five pot cultures, the total of treatments are 150 pot culture. The first factor are: kinds of host plant (A) with five levels i.e.: Pueraria javanica (A1), Centrocema pubescens (A2), Sorgum bicolor (A3), Cajanus cajan (A4), Zea mays (A5) and second factor are mycorrhyza fungi (B) which comprises two levels i.e.: Glomus sp (B1), Acaulospora sp (B2. The result of research showed that the highest average of spores number on P. javanica + Glomus sp as 38 spores and lowest on C.pubescens + Glomus sp and Z.mays + Glomus sp respectively as 28 spores. The percentage of root colonization for Glomus sp on kinds of host plant i.e.: P.javanica as 60.36%, S.bicolor as 47.93%, Z.mays as 35.36%, C. cajan as 21.72%, C.pubescens as 20.55%. The percentage of root colonization for Acaulospora sp on S.bicolor as 39.83%, C.cajan as 27.98%, C.pubescens as 26.57%, P.javanica as 23.82%, Z.mays as 21.20%. The highest average weight of shoot and root on treatment of P.javanica (A1) each 0.82 g and 0.91 g.
