摘要：

A pot experiment was conducted in the greenhouse to determine the influence of vesicular-arbuscular mycorrhizal (VAM) inoculation on growth of pineapple (Ananas comosus, cv.'Smooth Cayenne') and its interaction with fosetyl-Al in a Wahiawa soil (Tropeptic Eutrustox) at soil solution P levels of 0.003, 0.02 and 0.2 mg/L. Pineapple crowns were dipped in a solution of fosetyl-Al before planting. Inoculation of soil with the fungus Glomus aggregatum (Schenck & Smith emend. Koske) significantly increased VAM colonization of pineapple roots at soil solution P levels of 0.003 and 0.02 mg/L. VAM inoculation also increased mycorrhizal effectiveness measured six weeks after planting. At harvest, pineapple grown in the inoculated soil at the lowest P level had significantly higher D-leaf P concentration and plant fresh weight than that grown in the uninoculated soil. Fosetyl-Al appears to have no significant effect on VAM-pineapple interaction.
