Sucrose (a), glucose (b), and fructose (c) concentrations in leaf and root of trifoliate orange and white clover plants inoculated with Diversispora spurca in a two-compartmented rootbox separated by 37 μm nylon-mesh.

Data (means ± SD, n = 4) followed by different letters indicate significant differences (P < 0.05) between treatments. Abbreviation: TO⁺/WC⁺, both trifoliate orange and white clover plants were inoculated with D. spurca; TO⁺/WC^–, the donor plant trifoliate orange was inoculated with D. spurca, but the receptor plant white clover was not inoculated with D. spurca; TO^–/WC⁺, the donor plant white clover was inoculated with D. spurca, but the receptor plant trifoliate orange was not inoculated with D. spurca; TO^–/WC^–, both trifoliate orange and white clover were not inoculated with D. spurca.
