Abstract

The effect of vesicular arbuscular mycorrhizal (VAM) fungi inoculated with nematodes in roots of Luffa cylindrica

(L.) Roem was studied under greenhouse conditions. Six treatments were used; viz., C = Control, T1 = VAM only,

T2 = nematodes only, T3 = VAM and nematodes simultaneously, T4 = VAM fungi one week before nematodes and

T5 = VAM fungi one week after nematodes. Damage produced by nematodes was observed in T2 and T5, vascular

tissue obliterated by root-knot nematodes. However, VAM fungi suppressed the effects of root-knot nematodes in

T4. Giant cells, egg-masses and females of nematodes were observed in T2, T5 and to some extent in T3. VAM fungi

spores were seen in cortical as well as in pith region of root in T3.
