Soybean Response to Two Isolates of Meloidogyne arenaria.
Meloidogyne arenaria (Neal) Chitwood and M. incognita (Kofoid and White) Chitwood, prevalent in the sandy soils o f the southeastern United States, can severely limit soybean, Glycine max (L.) Merr., yield (10,12). Meloidogyne arenaria populations have increased in some southeastern states in recent years, apparently due to increased plantings of the soybean cultivar 'Centennial', which is resi...
متن کاملCellular Responses of Resistant and Susceptible Soybean Genotypes Infected with Meloidogyne arenaria Races 1 and 2.
The cellular responses induced by Meloidogyne arenaria races 1 and 2 in three soybean genotypes, susceptible CNS, resistant Jackson, and resistant PI 200538, were examined by light microscopy 20 days after inoculation. Differences in giant-cell development were greater between races than among the soybean genotypes. M. arenaria race 1 stimulated small, poorly formed giant-cells in contrast with...
متن کاملAggressiveness and Reproduction of Four Meloidogyne arenaria Populations on Soybean.
Aggressiveness and reproduction differed among four geographical populations of M. arenaria on six soybean cultivars in field microplots. These differences were consistent over 3 years. The populations did not differ in virulence; i.e., population by cultivar interactions were not significant. Perineal pattern morphology, the North Carolina differential host test, chromosome counts of immature ...
متن کاملSoybean-Peanut Rotations for the Management of Meloidogyne arenaria.
Rotating soybean (Glycine max cv. Kirby) with peanut (Arachis hypogaea cv. Florunner) for managing Meloidogyne arenaria race 1 was studied for 3 years (1985-87) in a field near Headland, Alabama. Each year soybean plots had lower soil numbers of M. arenaria second-stage juveniles (J2) at peanut harvest than did plots in peanut monocnlture. Peanut following either 1 or 2 years of soybean resulte...
متن کاملHost Status of Herbaceous Perennials to Meloidogyne incognita and M. arenaria.
Twenty-two different herbaceous perennials were studied for their reaction to separate inoculations of Meloidogyne arenaria and M. incognita under greenhouse conditions. Perennial taxa that did not develop root-galls following inoculation, and therefore are considered as nonhosts of both nematode species, included species and cultivars of Aethionema, Fragaria, Phlox, and Polygonum. Echinacea, M...
