Influence of Meloidogyne javanica and Rotylenchulus reniformis alone on nodulation of some leguminous crops
Journal Title: Egyptian Journal of Agronematology - Year 2016, Vol 15, Issue 1
Abstract
The effect of root-knot nematode, Meloidogyne javanica and the reniform nematode, Rotylenchulus reniformis alone on nodulation of four Rhizobium species on roots of 27 cultivars related to six leguminous species were evaluated. The formation of nodules on their roots varied greatly in their numbers according to host species, host cultivars, rhizobal species and nematode species. The greater nodulation reduction in infected roots with nematode species, M. javanica and R. reniformis was observed on roots of common bean cvs. Exira, Nebraska, Polista and Savana inoculated with rhizobial species Rhizobium phaseoli and lupine cv. Giza 2 inoculated with rhizobial species R. lupine. In general, inoculation of M. javanica or R. reniformis with rhizobial species greatly reduced root nodulation as compared to leguminous species inoculated with Rhizobium species alone. Also, it is important to note that the reduction in the number of bacterial nodules was more pronounced with R. reniformis infection than with M. javanica infection. It is noteworthy that the number of nodules on roots of broad bean cv. Wade 1 inoculated with R. phaseoli increased by both nematode species infections.
