This study investigated the accumulation of osmotic solutes in citrus (Poncirus trifoliata) seedlings colonized by Glomus versiforme subjected to drought stress or kept well watered. Development of mycorrhizae was higher under well watered than under drought-stressed conditions. Arbuscular mycorrhizal (AM) seedlings accumulated more soluble sugars, soluble starch and total non-structural carbohydrates in leaves and roots than corresponding non-AM seedlings regardless of soil-water status. Glucose and sucrose contents of well-watered and drought-stressed roots, fructose contents of well-watered roots and sucrose contents of drought-stressed leaves were notably higher in AM than in non-AM seedlings. K⁺ and Ca²⁺ levels in AM leaves and roots were greater than those in non-AM leaves and roots, while AM symbiosis did not affect the Mg²⁺ level. AM seedlings accumulated less proline than non-AM seedlings. AM symbiosis altered both the allocation of carbohydrate to roots and the net osmotic solute accumulations in response to drought stress. It is concluded that AM colonization enhances osmotic solute accumulation of trifoliate orange seedlings, thus providing better osmotic adjustment in AM seedlings, which did not correlate with proline but with K⁺, Ca²⁺, Mg²⁺, glucose, fructose and sucrose accumulation.
