Abstract

The effect of five species of vesicular-arbuscular mycorrhizal (VAM) fungi on the growth of Macroptillium atropurpureum Urb. V. Siratro in limed, nonpasteurized soil was studied under greenhouse conditions. Fungi tested were Glomus etunicatum Becker & Gerdemann, Glomus deserticola Trappe, Bloss & Menge, Glomus versiform Berch & Fortin, population of intraradices Schenck & Smith, and Gigaspora margarita Becker & Hall. Forty and 70 d after planting, plants inoculated with G. etunicatum and G. intraradices had shoot dry and root fresh weights that were significantly higher than the other VAM fungal treatments and noninoculated plants. A significant positive correlation was found between mycorrhizal root colonization, expressed as either percentage or total root length colonized, and shoot dry weight. Glomus etunicatum colonized roots more rapidly than the other VAM fungi tested. With careful selection of effective VAM fungi, the growth of Siratro can be significantly enhanced in a lime amended, nonpasteurized soil that contains an ineffective pop indigenous VAM fungi under amended soil conditions.
