Soil properties influencing phytoparasitic nematode populations in Chilean vineyards Lifecycles of parasitic nematodes take place in the rhizosphere, therefore their breeding, parasitism and mobility dynamics are inevitably influenced by the soil-root interaction. A study was performed to evaluate the influence of rootstocks to some plant parasitic nematodes under different soil conditions. Nematode populations were assessed for Chardonnay vines either ungrafted or grafted on two rootstocks (5BB, SO4) in three different alluvial soils in the central zone of Chile. Soils were two Inceptisols of the Casablanca Valley (Valparaíso region), the first one with minimal soil structure and with a densification zone in lower horizons (S1); the second was a Mollisol (S2) more structured than the others, situated at Melipilla (Metropolitan region); the third one was a sandy textural class (S3.) The soils were characterized physically and morphologically, and nematode genera were Fresh Corks Directly From Portugal 4th Generation Family Cork Producer CORK SUPPLIER?

Ungrafted Chardonnay had the highest populations of Meloidogyne spp. (root knot nematodes) in all three soils but only significant in S2 soil. P.M. Fajardo, E.E. Aballay and P.M. Casanova. Chilean J.
