MARTINEZ GALLARDO, José Ángel et al. Plant parasitic nematodes and its relation to soil factors of papaya in Colima, Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.1, pp.251-257. ISSN 2007-0934.
Within this article, a previous article presented the identification and quantification of populations of plant parasitic nematodes associated with papaya (Carica papaya L.) in Colima, Mexico. The aim of this study was to determine the relationship between soil factors (texture, organic matter content, electrical conductivity and pH) and populations of plant parasitic nematodes in papaya in Colima, Mexico. Root samples and soil from the rhizospherere were taken in 10 pieces of land in seven ranches from the municipalities of Colima and Tecomán, in Colima, Mexico; cultivated with papaya 'Maradol', 'Tainung' and 'Sensation'. From soil and roots collected, were detected and identified nematode populations; also soil characteristics were determined at each sampling site. A chi-square distribution or Pearson test was performed, to test the association between plant nematodes genus and different types of soil textures. Likewise, a multiple linear regression between nematode populations and soil factors was performed. Soil textures were loamy sand, sandy loam, sandy clay loam and sandy clay. There is a correlation between phytonematodes genus and types of soil texture, finding sandy loam texture as most suitable for the life cycle of plant parasitic nematodes.
