Interaction of Meloidogyne javanica with Different Races of Meloidogyne incognita.
The interspecific interactions of Meloidogyne javanica with races 1, 2, 3, and 4 of M. incognita on tomato were determined. Impacts of the interactions on fecundity and morphometrics of females were also examined. Mutually inhibitory interactions occurred between M. javanica and the races of M. incognita, but the negative interactions did not reflect in plant growth. Numbers of root galls, egg ...
متن کاملInteraction of Meloidogyne hapla and M. javanica Infecting Tomato.
A soil temperature of 20 C was equally suitable for the invasion and development of M. hapla and M. javanica. However, M. javanica predominated in a mixed species infection at this temperature. Predominance increased with increasing mixed-species inoculum levels. Invasion by M. hapla was more density-dependent than M. javanica. M. hapla produced a greater incidence of terminal galls and lateral...
متن کاملEvolutionary dynamics of Ralstonia solanacearum.
We investigated the genetic diversity, extent of recombination, natural selection, and population divergence of Ralstonia solanacearum samples obtained from sources worldwide. This plant pathogen causes bacterial wilt in many crops and constitutes a serious threat to agricultural production due to its very wide host range and aggressiveness. Five housekeeping genes, dispersed around the chromos...
متن کاملMeloidogyne javanica Parasitic on Peanut.
Peanut fields in four governorates of Egypt were surveyed to identify species of Meloidogyne present. Fourteen populations obtained from peanut roots were all identified as M. javanica based on perineal patterns, stylet and body lengths of second-stage juveniles, esterase phenotypes, and restriction fragment length polymorphisms of mtDNA. Three of 14 populations, all from contiguous fields in t...
متن کاملMeloidogyne javanica on Peanut in Florida.
A mixed population of Meloidogyne arenaria race 1 and M. javanica race 3 is reported on peanut from a field in Levy County, Florida. Confirmation of M. javanica on peanut is based on esterase and malate dehydrogenase isozyme patterns resolved on polyacrylamide slab gels following electrophoresis, and perineal patterns. Up to 29% of 290 individual females collected from peanut roots in the field...
