摘　　要：采用盆栽试验,研究了摩西球囊霉(Glomus mosseae)、脆无梗囊霉(Acaulospora delicata)、隐类球囊霉(Paraglomus occultum)和幼套球囊霉(Glomus etunicatum)4种丛枝菌根真菌对桃[Prunus persica(L.)Batsch]幼苗生长及硒富集特性的影响。结果表明,施用脆无梗囊霉增加了桃幼苗的生物量,促进了桃幼苗的生长,使桃幼苗的根系和地上部分生物量分别比未施用增加了11.28%和9.18%,也在一定程度上提高了光合色素含量、过氧化酶活性及过氧化氢酶活性。施用摩西球囊霉、隐类球囊霉和幼套球囊霉3种丛枝菌根真菌降低了桃幼苗的生物量、光合色素含量及抗氧化酶活性或对其没有显著影响。施用脆无梗囊霉也在一定程度上增加了桃幼苗的总硒含量及有机硒含量,其中地上部分的总硒含量和有机硒含量分别较未施用增加了8.01%和9.34%。施用摩西球嚢霉、隐类球囊霉和幼套球囊霉降低了桃幼苗的总硒含量及有机硒含量或对其没有显著影响。The effects of four arbuscular mycorrhizal fungi Glomus mosseae,Acaulospora delicata,Paraglomus occultum and Glomus etunicatum on growth and selenium accumulation of peach[Prunus persica(L.)Batsch]seedlings were studied by a pot experiment.The results showed that application of Acaulospora delicata increased the biomass of peach seedlings,promoted the growth of peach seedlings,and increased the biomass of the root and aboveground parts of peach seedlings by 11.28%and 9.18%,respectively,compared with no application.It also increased the content of photosynthetic pigments,peroxidase activity and catalase activity to a certain extent.Application of Glomus mosseae,Paraglomus occultum and Glomus etunicatum decreased the biomass,photosynthetic pigment content and antioxidant enzyme activity of peach seedlings or had no significant effects on them.Application of Acaulospora delicata also increased the total selenium content and organic selenium content in peach seedlings to a certain extent,and the total selenium content and organic selenium content in shoots increased by 8.01%and 9.34%,respectively,compared with no application.Application of Glomus mosseae,Paraglomus occultum and Glomus etunicatum decreased the total selenium and organic selenium contents in peach seedlings or had no significant effects on them.
