Abstracts |
Studies on tripartite interactions between vesicular arbuscular mycorrhiza (VAM), root lesion nematode and wheat cultivars were carried out in soil pots to find out the potentiality of VAM fungus (Glomus mosseae) in limiting the activities of root lesion nematode (Pratylenchus sp.) in rhizospheres of 6 wheat cultivars. Resistance/susceptibility of the wheat cultivars towards the nematode/VAM fungus was also observed. On separate inoculations of G. mosseae and Pratylenchus sp., cultivar Blue silver showed a positive response towards VAM fungus (85.58+or-4.7% infection) but showed the highest resistance to nematodes (16.75+or-6.8% disease severity; DS). However, cultivar Mexi Pak showed susceptibility towards nematode (48.08+or-08% DS) and comparatively less response towards VAM fungus (55.18+or-7.7% infection). The combined inoculations (G. mosseae+Pratylenchus sp.) showed a significant reduction (P<0.05) in root DS and the population of Pratylenchus sp. in rhizospheric regions of all wheat cultivars except Mexi Pak compared to the control set of pots. Blue Silver showed the highest reduction in Pratylenchus sp. population (62.5+or-04.71%) while Mexi Pak (06.8+or-05.56%) showed the least population reduction. |
