摘　　要：为探究在未灭菌的土壤条件下接种3种AM真菌对桑树生长发育及其活性物质的影响,以‘特优2号’桑树品种为试材,自然泥土为基质,设置对照组(CK)和接种幼套近明球囊霉(Claroideoglomus etunicatum,CE)、摩西斗管囊霉(Funneliformis mosseae,FM)、根内根孢囊霉(Rhizophagus intraradices,RI)4个处理进行盆栽试验。生长120 d测得桑树的生物量、桑叶的类胡萝卜素和黄酮类化合物等数据。研究结果表明,接种CE、FM和RI的根鲜重比对照组分别增加了57.57%、81.92%和90.03%;与CK相比,接种CE、FM和RI的根干重分别增加了24.10%、47.65%和72.58%;与CK相比,接种CE、FM和RI的净光合速率分别增加了20.73%、4.22%和25.41%,类胡萝卜素含量分别增加了28.57%、28.57%和35.71%,接种CE、FM和RI的桑叶中的黄酮类化合物平均含量分别为4.23 mg/g、3.31 mg/g、3.85 mg/g,均高于CK的2.55 mg/g。在未灭菌的土壤环境下接种AM真菌对桑树的生长发育有不同的影响,促进了桑树根系生长,增加了桑叶的活性物质积累,与桑树有较好的共生关系。This study explores the effects of inoculating three types of arbuscular mycorrhizal(AM)fungi on the growth and development,and active compound production of mulberry trees in non-sterilized soil.Using the‘TeYou No.2’mulberry variety as material and natural soil as the substrate,we conducted a pot experiment with four treatments:a control group(CK),and inoculations with Claroideoglomus etunicatum(CE),Funneliformis mosseae(FM),and Rhizophagus intraradices(RI).After 120 days,data on mulberry biomass,leaf carotenoids,and flavonoids were collected.The results revealed that,compared to the control group,root fresh weights increased by 57.57%,81.92%,and 90.03% for CE,FM,and RI inoculations,respectively,while root dry weights rose by 24.10%,47.65%,and 72.58%.The net photosynthetic rates for CE,FM,and RI increased by 20.73%,4.22%,and 25.41%,respectively,and carotenoid content grew by 28.57%,28.57%,and 35.71%.The average flavonoid content in leaves for CE,FM,and RI was 4.23 mg/g,3.31 mg/g,and 3.85 mg/g,all exceeding the control group’s 2.55 mg/g.Inoculation with AM fungi in non-sterilized soil positively impacted mulberry growth,enhanced root development,increased active compound accumulation in leaves,and fostered a beneficial symbiotic relationship with the mulberry trees.
