Susceptibility 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 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 کاملSuitability 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 کاملUPTAKE AND TRANSLOCATION OF NITROGEN, PHOSPHORUS AND CALCIUM IN SOYBEAN INFECTED WITH Meloidogyne incognita AND M. javanica
Two soybean (Glycine max) cultivars were used in this study, Ocepar 4, rated as moderately resistant to Meloidogyne incognita race 3 but susceptible to M. javanica, and ‘BR 16’, susceptible to both nematodes. The effect of nematodes infection on the uptake and transport of N, P and Ca to the shoot was studied in plants growing in a split root system. The upper half was inoculated with 0, 3,000,...
متن کاملPepper Rootstock Graft Compatibility and Response to Meloidogyne javanica and M. incognita.
Resistance of pepper species (Capsicum annuum, C. baccatum, C. chinense, C. chacoense, and C. frutescens), cultivars and accessions to the root-knot nematodes Meloidogyne incognita race 2 and M. javanica, and their graft compatibility with commercial pepper varieties as rootstocks were evaluated in growth chamber and greenhouse experiments. Most of the plants tested were highly resistant to M. ...
