Nonmycorrhizal or mucorrhizal (Glomus fasciculatum, G. etunicatum, or Gigaspora heterogama) sour orange (Citrus aurantium L.) seedlings were fertilized with 3 phosphorus levels applied in the irrigation water. At 0mg P/L fertility, dry weight and cytokinin production of mycorrhizal plants were more than twice those of the nonmycorrhizal plants. concentrations of P in leaves of mycorrhizal plants also were greater than the concentrations of P in the nonmycorrhizal plants. at 50 mg P/L fertility, concentrations of P in leaves were similar whether or not plants were mycorrhizal. dry weight and cytokinin production of the mycorrhizal plants, however, were still twice those of the nonmycorrhizal plants. At 100 mg P/L fertility, dry weight and cytokinin did not differ betweem nonmycorrhizal plants and plants infected with 2 of 3 mycorrhizal fungi. In G. heterogama-infected plants, cytokinin production was greater than that of nonmycorrhizal plants despite similar dry weights and P concentrations in the leaves. Enhancement of cytokinin production seemed to be associated with mycorrhizal infection rather than with increased P uptake. |
