Abstract
The response of peanut to salt (NaCl) and acid (HCl) stress was studied in association with Glomus caledonium, an arbuscular mycorrhizal (AM) fungus. The plants were exposed to salt stress by irrigation on alternate days with 1% or 5% NaCl solutions, or with 0.1 N HCl to induce acid stress. Plant yield almost tripled in mycorrhizal plants compared with nonmycorrhizal control plants. AM inoculation significantly increased plant yield and biomass at 1% NaCl, while at 5% NaCl AM was less effective in alleviating salt stress. Percentage AM colonization was also lowest at 5% NaCl. AM inoculation was found to promote the establishment of peanut plants under acid stress conditions.
