摘要

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.

Javanica,M.Arenaria和M.Incognita等)感染,并且已经发现只有几种具有一些对这些线虫抗性的品种。使用高种植密度,灌溉和大量肥料的强化橄榄生长的创新可能会增加线虫人口进一步破坏水平。为了进一步了解橄榄和病原线虫之间所涉及的相互作用,并希望对农业风险寻找解决方案,这项研究旨在确定西班牙和野生橄榄中重要橄榄品种对M. javanica感染的反应,包括相同的基因型和其他O. Ouropaea亚种。所有测试的橄榄品种都是M. Javanica的好主持人,但三个品种(Gordal Sevillana,Hojiblanca和Manzanilla de Sevilla)发现的高水平的线虫繁殖基本不同。在野生加入中,O. Europaea Subsp。 CeraSiformis(基因型W147)和O. Europaea患者。欧洲否。 Sylvestris(基因型W224)在不同水平下对M. Javanica抗性,在W147(再生因子[RF] = 0.0003)中具有很强的抗性(RF = 0.79)中的中等抗性。 W147至M. Javanica的防御反应显示出酚类化合物的强烈增加,但没有过敏反应。
