S ummary Nine vesicular‐arbuscular mycorrhizal endophytes were assessed for their infectivity and ability to improve the growth of alpine strawberry seedlings in sterilized, low‐phosphate soils (4 and 8 mg kg −1 NaHCO 3 ‐soluble P), limed to different pHs. At pH 4, Glomus clarum greatly stimulated plant growth, but the other endophytes except Gigaspora margarita and Glomus fasciculatum ‘E3’ had little or no effect. The most efficient endophytes at pH 5 were E3, Acaulospora laevis and G. clarum. The largest plants were those growing at pH 7 and inoculated with Glomus epigaeum; A. laevis and G. clarum were ineffective at this pH. The most effective endophytes at pH 6 and 7 were G. epigaeum, Glomus mosseae , E3, Glomus caledonium and Gigaspora heterogama , although results varied slightly between soils. Most endophytes infected well at all pHs, even where they did not enhance plant growth. In studies of this nature plant growth is affected by different pHs, soil P levels and the inoculum used. Nevertheless these data show clearly that different endophytes vary enormously in their symbiotic effectiveness at different soil pHs. The practical implications of these results are discussed.
