“…The economic importance of M. baetica is unknown, but it infects common olive rootstocks, and its histopathology and population development on olive are similar to those reported for other root knot species. Lamberti et al (2001) found some evidence that infection by M. incognita enhances damage by the wilt-inducing fungus Verticillium daliae. P. vulnus has been implicated by Lamberti (1969) as a factor in olive decline in Italy, and has been demonstrated in inoculation trials as a potential pathogen of olive (Lamberti and Baines, 1969b).…”

“…and Tylenchulus semipenetrans (Cobb, 1913) ranged from 5 to 10% (Koenning et al 1994;Singh et al 2013). In some cases plant-parasitic nematodes are associated with damaging syndromes such as "drying syndrome" in newly established olive orchards in Argentina (Pérez et al 2001) or with vascular diseases (Lamberti et al 2001;Saeedizadeh et al 2003). Damage in nursery plants is more severe due to nematode parasitism and more importantly, plantparasitic nematode populations are disseminated from nurseries to uninfested areas (Nico et al 2002).…”

Evaluation of the Phytopathological Reaction of Wild and Cultivated Olives as a Means of Finding Promising New Sources of Genetic Diversity for Resistance to Root-Knot Nematodes

Olive (Olea europaea L.) is one of the most important fruit crops in the Mediterranean Basin, because it occupies significant acreage in these countries and often has important cultural heritage and landscape value. This crop can be infected by several Meloidogyne species (M. javanica, M. arenaria, and M. incognita, among others), and only a few cultivars with some level of resistance to these nematodes have been found. Innovations in intensive olive growing using high planting densities, irrigation, and substantial amounts of fertilizers could increase the nematode population to further damaging levels. To further understand the interactions involved between olive and pathogenic nematodes and in the hope of finding solutions to the agricultural risks, this research aimed to determine the reaction of important olive cultivars in Spain and wild olives to M. javanica infection, including genotypes of the same and other O. europaea subspecies. All olive cultivars tested were good hosts for M. javanica, but high levels of nematode reproduction found in three cultivars (Gordal Sevillana, Hojiblanca, and Manzanilla de Sevilla) were substantially different. In the wild accessions, O. europaea subsp. cerasiformis (genotype W147) and O. europaea subsp. europaea var. sylvestris (genotype W224) were resistant to M. javanica at different levels, with strong resistance in W147 (reproduction factor [Rf] = 0.0003) and moderate resistance in W224 (Rf = 0.79). The defense reaction of W147 to M. javanica showed a strong increase of phenolic compounds but no hypersensitive reaction.

“…Europaea), are essentially grown in sub tropical climatic conditions (Argen-... tina, Australia, California, Chile, China, Mexico, Perù, Iran, Iraq, Jordan and South Africa) and especially in the countries of the Mediterranean Basin where about 85 % of the world olive production is concentrated. Over one hundred species of phytoparasitic nematodes have been reported in association with olive (Lamberti & Vovlas, 1993;Nico et al, 2002;Sasanelli, 2009). However, only a few genera and species can affect growth of olive trees such as the root-lesion nematodes Pratylenchus vulnus and P. penetrans, the citrus nematode Tylenchulus semipenetrans, Gracilacus peratica, Rotylenchulus macrodoratus, the longidorids Xiphinema elongatum and X. index, and the root-knot nematodes Meloidogyne spp.…”

“…Among all, rootknot nematodes, being polyphagous, are the most destructive plant parasitic nematodes causing severe damage to olive seedlings and groves. Mechanical injury caused by feeding mechanism of second stage juvenile of Meloidogyne on the roots of young olive tree favours penetration and infection of the root tissue by soil borne pathogen especially Verticillium dahliae (Lamberti et al, 2001). Root-knot nematodes often damaged young olive plants in pots in nurseries.…”

The influence of ten initial population levels (0, 0.1, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8 and 25.6 second stage juveniles/cm3 soil) of Meloidogyne incognita and M. javanica on olive cultivar Zard growth was studied in two pot trials. Ten month old self-rooted olive cuttings were individually transplanted into 2 000 cm3 pot and inoculated with the defined initial populations, of both nematode species. Plants were grown in glasshouse for 13 months, then they were uprooted and plant growth (percent growth increase of main shoot length, number of nodes on main shoot, top and root fresh and dry weights and root length) and nematode parameters (root gall index, J2/g root, final nematode population density and reproduction rate Pf/Pi) were recorded. Results showed that cv. Zard was more susceptible to M. javanica than to M. incognita. A significant reduction of main shoot length growth 37.6 % and 10.7 % was observed at 0.1 and 12.8 juveniles/cm3 soil of M. javanica and M. incognita, respectively, in comparison to uninfested plants. Root systems of olive plants grown in M. incognita or M. javanica infested soils were galled within the gall index range 1.4–6. No significant differences were observed in the number of nodes on main shoot, top and root fresh weights and root dry weight at high levels of M. incognita Pi. A tolerance limit (T) of 0.4 juveniles/cm3 soil was estimated for olive plants cv. Zard to M. javania. The use of resistant olive rootstock or selected cultivars is recommended to minimize or to limit damage of nematode infections in nurseries and to prevent secondary attacks of soil borne plant pathogens especially Verticillium dahliae.
