F% Frequency of mycorrhizal root segments, NM: Non-mycorrhizal plants and M: Mycorrhizal plants, DW: Dry weight MD% mycorrhizal dependency = [(DW of M - DW of NM)/ DW of M] x 100, DI%: Disease Incidence; R/S: Root / shoot. LSD: At significant level (P > 0.05).Sample symbols (a.a) mean non significant difference, (a.b) mean significant difference
