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。

Abstract:

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.
