Resistance and host-response of selected plants to Meloidogyne megadora.
Fourteen plant species, including 30 genotypes, were assessed for host suitability to Meloidogyne megadora in a growth room at 20 to 28 degrees C. Host suitability was based on the gall index (GI) and the reproduction factor (Rf):final population density (Pf)/initial population density (Pi). The presence of distinct galling was observed on roots of six plant species, and reproduction occurred o...
متن کاملHost Status of Thirteen Acacia Species to Meloidogyne javanica.
Thirteen indigenous and exotic Acacia species grown in Saudi Arabia were evaluated for their host status for Meloidogyne javanica in pot tests both in the growth chamber and under outdoor conditions. In both experiments, 21-day-old seedlings were transplanted individually into 15-cm-diam. plastic pots containing a steam-sterilized mixture of equal parts loam and sandy loam. Seedlings were inocu...
متن کاملHost Status of 32 Plant Species to Meloidogyne konaensis.
A host suitability study of 32 plant species to Meloidogyne konaensis included 54 vegetable cultivars, 12 field crop cultivars, one Gardenia sp., and two weed species. Host suitability was classified according to a M. konaensis reproductive factor: final population density (Pf) (eggs + J2) / initial population density (Pi) (eggs). The number of eggs per gram dry root, and a galling index was al...
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...
متن کاملHost status of endophyte-infected and noninfected tall fescue grass to Meloidogyne spp.
Tall fescue grass cultivars with or without endophytes were evaluated for their susceptibility to Meloidogyne incognita in the greenhouse. Tall fescue cultivars evaluated included, i) wild-type Jesup (E+, ergot-producing endophyte present), ii) endophyte-free Jesup (E-, no endophyte present), iii) Jesup (Max-Q, non-ergot producing endophyte) and iv) Georgia 5 (E+). Peach was included as the con...
