In 2013, an unidentified species of Dendrochilum appeared in cultivation under the commercial trade name 'Big Pink'. Using sequences of the nuclear ribosomal ITS1-5.8S-ITS2 region and of the plastid matK and ycf1 genes, we examined the phylogenetic relationships between 'Big Pink' and six other species of the phenetically defined Dendrochilum subgen. Platyclinis sect. Eurybrachium. Separate and...
Reproduction ofMeloidogyne incognita and M. arenaria was determined on 25 commercial tropical corn hybrids in greenhouse studies. Soil around corn seedlings was infested with 3,000 eggs/plant. Reproduction was quantified from counts of egg masses on roots stained with phloxine B 60 days after soil infestation. All of the tropical hybrids were susceptible to M. incognita and M. arenaria. Egg mas...
Ninety-six isolates of Meloidogyne species collected from banana fields from Martinique, Guadeloupe, and French Guiana, were examined using esterase (Est) and malate dehydrogenase (Mdh) phenotypes. Adult females identified as M. arenaria, M. incognita, M. javanica, M. cruciani, M. hispanica, and Meloidogyne sp. showed species-specific phenotypes only for the esterase enzymes. Intraspecific vari...
The effects of Meloidogyne incognita race 3 and M. arenaria race 1 on growth of kenaf cv. Everglades 41 was determined under greenhouse conditions. Seedlings of kenaf were inoculated with initial population densities (Pi) of 0, 625, 1,250, 2,500, 5,000, and 10,000 eggs/plant and placed on greenhouse benches in a randomized complete block design. Plant growth and nematode reproduction were asses...
Meloidogyne incognita and M. arenaria reproduction and host plant tolerance were assessed in field and greenhouse experiments on seven holly cultivars including Ilex glabra 'Shamrock', I. vomitoria 'Schelling's Dwarf', I. cornuta 'Carissa', red holly hybrid (Ilex Little Red), and I. crenata 'Compacta', 'Green Luster', and 'Helleri' as well as Japanese boxwood (Buxus microphylla) and two lantana...
جنس colutea l. (fabaceae) نُه گونه در ایران دارد: c. cilicica (sect. colutea subsect. arborescentes)، c. persica و c. gracilis (sect. colutea subsect. graciles)، c. x variabilis (sect. rostrata subsect. orientales)، c. buhsei (sect. rostrata subsect. centralasiaticae)، c. gifana (sect. rostrata subsect. gifana)، c. uniflora (sect. rostrata subsect. uniflora)، c. komarovii و c. porphyrogramma (se...
The reproductive potential and damage functions for Meloidogyne hapla and M. arenaria race 1 on Virginia-type peanuts (Arachis hypogaea cv. Florigiant) were determined over 2 years in microplot experiments in North Carolina. Peanut yield suppression and damage to pods as a result of galling were greatest in response to M. arenaria (P = 0.01). Damage functions for the two species were adequately...
A total of 33 corn hybrids were evaluated in a series of greenhouse and field trials to determine if they differed in resistance to either Meloidogyne incognita race 3 or M. arenaria race 1. Reproduction of M. incognita race 3 and M. arenaria race 1 on the hybrids was also compared. Reproduction of M. arenaria differed among corn hybrids after 58 to 65 days in greenhouse experiments; however, r...
Two new Vertomannus species, Vertomannus flavus sp. n. (south Vietnam) and Vertomannus borneensis sp. n. (Borneo) are described. Vertomannus (Elongatomannus), subgen. n. (type species: Vertomannus flavus) is proposed.
