Assessment of faba bean damage caused by Meloidogyne incognita root-knot nematode infection
Pakistan Journal of Nematology 22 (1), 47-53
Abstract: Under greenhouse conditions, faba bean (Vicia faba L.) plants inoculated with 0, 10, 100, 1000 and 10,000 larvae of Meloidogyne incognita root-knot nematode per pot showed significant reduction in plant growth and yield under the highest inoculum (p < 0.05 and/or 0.01). Number of nematode galls was greatly affected by the initial nematode population. Cellular alterations of faba bean root infected with the Meloidogyne incognita root-knot nematode showed that 2nd stage nematode larvae penetrated the roots of faba bean by puncturing action of the stylet and inter-intra cellular migration into the cortex and endodermis layers causing damage to the cells. Mature females and thick-walled multinucleate giant cells with dense and granular cytoplasm were formed in the cortex, endodermis and stele regions.
