The effects of an arbuscular mycorrhizal fungus, Diversispora spurca, on plant growth, root morphology, chlorophyll concentration, and carbohydrate contents in trifoliate orange grown in a rootbox divided by 37- or 0.45-μm mesh were studied. After 18 weeks of mycorrhizal inoculation, root colonization was higher under 37-μm mesh than under 0.45-μm mesh. Mycorrhizal inoculation significantly increased growth performance (plant height, stem diameter, leaf number, shoot and root biomass) and root morphology (the number of 1st-, 2nd-, and 3rd-order lateral roots, root length, projected area, surface area, volume, tips, forks, and crossings), and the effects were superior under 37-μm than 0.45-μm. In addition, mycorrhizal colonization dramatically increased chlorophyll a, chlorophyll b, carotenoids, and total chlorophyll concentrations and also promoted sucrose and glucose contents in leaf, root, and total plant. These results indicate that mycorrhiza-promoted effects on growth and root morphology are potentially associated with changes in chlorophyll and carbohydrates
