Suitability of Zucchini and Cucumber Genotypes to Populations of Meloidogyne arenaria, M. incognita, and M. javanica.
The host suitability of five zucchini and three cucumber genotypes to Meloidogyne incognita (MiPM26) and M. javanica (Mj05) was determined in pot experiments in a greenhouse. The number of egg masses (EM) did not differ among the genotypes of zucchini or cucumber, but the eggs/plant and reproduction factor (Rf) did slightly. M. incognita MiPM26 showed lower EM, eggs/plant, and Rf than M. javani...
متن کاملSusceptibility of Several Common Subtropical Weeds to Meloidogyne arenaria, M. incognita, and M. javanica.
Experiments were conducted in the greenhouse to assess root galling and egg production of three root-knot nematode species, Meloidogyne arenaria, M. incognita, and M. javanica, on several weeds common to Florida agricultural land. Weeds evaluated were Amaranthus retroflexus (redroot pigweed), Cyperus esculentus (yellow nutsedge), Eleusine indica (goosegrass), Portulaca oleracea (common purslane...
متن کاملSensitive PCR Detection of Meloidogyne arenaria, M. incognita, and M. javanica Extracted from Soil.
We have developed a simple PCR assay protocol for detection of the root-knot nematode (RKN) species Meloidogyne arenaria, M. incognita, and M. javanica extracted from soil. Nematodes are extracted from soil using Baermann funnels and centrifugal flotation. The nematode-containing fraction is then digested with proteinase K, and a PCR assay is carried out with primers specific for this group of ...
متن کاملBeta-Glycosidases from Meloidogyne incognita and M. javanica.
B-glycosidases have been implicated in plant pathogenesis by numerous authors (6,8,9,10). B-glucosidase from Pratylenchus penetrans was reported to hydrolyse HCN from a cyanogenic glucoside (amygdalin) during pathogenesis of peach roots (7), and the activity of B-glucosidase from preparasitic larvae of Heterodera rostochiensis has been correlated with the ability to parasitize resistant potato ...
متن کاملEffects of Pangola,Digitgrass on Meloidogyne arenaria, M. javanica, and M. hapla.
Pangola digitgrass (Digitaria decumbens Stent.) can be used as a pasture grass or it can be harvested as hay. I t originated in Africa and has been in t roduced to other tropical and subtropical areas of the world. Winchester and Haysl ip (5) repor ted that the grass e l iminated populat ions of the root¬ nematode, Meloidogyne incognita acrita Chitwood and Oteifa, 1952. Overman (3) sampled 7...
