摘　　要：于日光温室条件下,研究了丛枝菌根真菌Glomusmosseae(Nicol.&Gerd.)Gerd.&Trappe,GlomusintraradicesSchenck&Smith和Glomusversiforme(Karsten)Berch对重茬土壤中草莓生长、结实和品质的影响。结果表明,供试真菌在同一时期的侵染率不同,同一菌种在不同时期侵染率有较大区别;无论土壤消毒与否,它们均可促进草莓的生长发育,提早开花4～12d,显著提高草莓单果重、单株果数和单株产量,单株产量提高27.6%～39.5%,提早4～6d成熟,而且有利于草莓前期产量的形成。接种处理还提高了草莓果实中维生素C和糖的含量,降低了可滴定酸的含量,改善了草莓果实品质。其中以Glomusversiforme接种效应最大。Effects of arbuscular mycorrhizal(AM)fungi,Glomus mosseae(Nicol.&Gerd.)Gerd.&Trappe,Glomus in-traradices Schenck&Smith,Glomus versiforme (Karsten)Berch on the yield and quality of strawberry grown in pots filled with replanted soil were investigated under greenhouse conditions.Results showed that there were significant differences in colonization percentage of AM fungal species in various stages.The growth,weight per fruit,number of fruit and yield per plant grown in both sterilized and non-sterilized soil were increased by AM fungal colonization.The blossom date was4～12days and the ripening date4～6days earlier compared to the control.The yield per plant was increased by27.6%～39.5%and improved the earlier yield of strawberry treated with AM fungi.The contents of Vc and sugar were enhanced,while the titrat-able acid content in the fruit was reduced by AM fungus colonization.Among the AM fungi,Glomus versiforme was the most effective.
