摘要：

Two species of arbuscular mycorrhizal (AM) fungi (Glomus intraradices, Glomus caledonium) introduced during post vitro acclimatization were tested for infection development and growth effects in Prunus avium, after transplantation into two types of disinfected or undisinfected neutral soils. Endomycorrhizal plants grew better than nonmycorrhizal plants in both disinfected soils. Growth improvements by either fungus were related to a high level of mycorrhizal colonization. Mycorrhizal effects on P avium plants and mycorrhiza development depended on the soil type. In undisinfected soils containing an infective but inefficient AM fungal population, growth of Prunus was improved by preinoculation with effective AM fungi adapted to the soil type. Moreover, clonal variations in AM development and mycorrhizal responsiveness to Glomus mosseae were observed in three P avium clones. The bioprotective effect of AM was shown in one clone where the presence of G mosseae eliminated the negative impact of Phytophthora cinnamomi on root growth.
