Host Response of Ornamental Palms to Rotylenchulus reniformis.
The responses of 20 species of ornamental palms and one cycad (Cycas revoluta) to two populations of the reniform nematode, Rotylenchulus reniformis, from southern Florida were studied in two greenhouse experiments conducted in 1989-1991 and 1991-92. Ornamental palms in pots were exposed to initial population densities of 400 and 1,500 R. reniformis/l00 cm(3) soil for 16 and 15 months, respecti...
متن کاملHost Status of Commercial Maize Hybrids to Rotylenchulus reniformis.
The host status of 50 commercial maize hybrids for a Mississippi population of Rotylenchulus reniformis was determined in greenhouse experiments. Reproduction was measured by determining RF values ([final egg number + juveniles and vermiform adults in soil] / initial egg number) and number of eggs per gram of fresh root. All hybrids maintained R. reniformis below the initial population level, i...
متن کاملIdentification of fungi associated with rotylenchulus reniformis.
The objective of this work was to isolate and identify fungi associated with R. reniformis in cotton roots. Soil samples were collected in cotton fields naturally infested with R. reniformis and from cotton stock plants cultured in the greenhouse. Nematodes extracted from the soil were observed under the stereoscope, and discolored eggs and vermiform stages colonized with mycelia were cultured ...
متن کاملPathogenicity and Histopathology of Rotylenchulus reniformis Infecting Cantaloup.
Rotylenchulus reniformis was pathogenic to cantaloup (Cucumis melo 'Perlita') under greenhouse conditions. These findings confirm field symptoms of cantaloup infected with R. reniformis. Histopathological studies show that the nematode penetrates the cortex perpendicular to the vascular system and comes to rest with the head against the endodermis in young roots. Feeding stimulated the pericycl...
متن کاملRotylenchulus reniformis on Greenhouse-grown Foliage Plants: Host Range and Sources of Inoculum.
Two sources of inoculum of reniform nematodes, Rotylenchulus reniformis, were identified for infestation of ornamental foliage plants in commercial greenhouses. These were water from a local canal system and rooted cuttings purchased from other sources. Eight ornamental plant species were identified as good hosts for the reniform nematode, with each species supporting a reniform population dens...
