虽然大多数园艺作物都依赖于菌根，但在高投入农业中，丛枝菌根（AM）接种在植物生产中的作用一直被忽视。球囊霉属的商业接种物混合物的现场应用。以辣椒（Capsicum annuum L.）变种longum），cv.塞盖迪，耕种。与聚合酶链反应-限制性片段长度多态性（PCR-RFLP），小亚基核糖体RNA基因的差异被用来表征集团的丛枝菌根真菌（AMF）的影响，菌根接种土著AMF人口。AMF接种体能在辣椒根际生根，与未接种的对照相比，辣椒产量增加65%以上。在对照中具有相对较高的根定殖，未接种处理表明田间土壤中存在较高的AMF土著种群。虽然接种影响居民AM真菌群落的结构，它没有影响与辣椒根相关的AM真菌的组成显着。
Although the majority of horticultural crops are mycorrhiza-dependent, the role of arbuscular mycorrhizal (AM) inoculation in plant production has been neglected in high-input agriculture. Field application of a commercial inoculum mix of Glomus spp. was tested in spice pepper (Capsicum annuum L. var. longum), cv. Szegedi, cultivation. With polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), differences in small subunit ribosomal RNA genes were used to characterize groups of arbuscular mycorrhizal fungi (AMF) with respect to effects of mycorrhizal inoculation on an indigenous AMF population. The AMF inoculant was able to establish in the rhizosphere of pepper plants and mycorrhizal inoculation increased yield of spice pepper by more than 65% compared with the non-treated control plants. Having relatively high root colonization in the control, non-inoculated treatment indicated high presence of indigenous populations of AMF in the field soil. Although the inoculation affected structure of the resident AM fungal community, it did not influence the composition of AM F associated with pepper roots significantly.
