摘要：Genetic variation in growth, ectomycorrhizal development and phosphorus (P) uptake by seedlings of four provenances of Eucalyptus urophylla were compared in a sand culture study at 5, 10 and 20 mg P kg(-1) soil. There were marked variations in plant dry weight and P content between E. urophylla provenances at intermediate levels of P addition to soil (10 mg P kg(-1), but variations in these factors were less at either the higher or lower P levels. Most of the provenances inoculated with Pisolithus tinctorius and Scleroderma cepa showed increased biomass and P uptake at the low level (5 mg P kg(-1)) and reduced or no effect on biomass and P uptake at adequate P supply to seedling growth (20 mg P kg(-1) soil). Different combinations between provenances and fungi had different (positive and negative) effects on biomass and P uptake.
