The use of arbuscular mycorrhizal fungi (AMF) offers promising benefits to agriculture in the Amazon regions, where soils are characteristically acidic and nutrient-poor. The purpose of this research was to investigate the potential effects of two recently described species of AMF ( and ) native to the Peruvian Amazon for improving the plant growth of (inka nut or sacha inchi) and protecting the roots against soil pathogens. Two assays were simultaneously conducted under greenhouse conditions in Peru. The first focused on evaluating the biofertilizer effect of AMF inoculation, while the second examined the bioprotective effect against the root knot nematode, . Overall, the results showed that AMF inoculation of seedlings positively improved their development, particularly their biomass, height, and the leaf nutrient contents. When seedlings were exposed to , plant growth was also noticeably higher for AMF-inoculated plants than those without AMF inoculation. Nematode reproduction was significantly suppressed by the presence of AMF, in particular , and especially when inoculated prior to nematode exposure. The dual AMF inoculation did not necessarily lead to improved crop growth but notably improved P and K leaf contents. The findings provide strong justification for the development of products based on AMF as agro-inputs to catalyze nutrient use and uptake and protect crops against pests and diseases, especially those that are locally adapted to local crops and cropping conditions.
丛枝菌根真菌（AMF）的使用为亚马逊地区的农业带来了可观的益处，该地区土壤的典型特征是酸性且养分贫瘠。本研究的目的是调查两种最近描述的原产于秘鲁亚马逊地区的AMF（ 和 ）对改善 （印加果或美藤果）植物生长以及保护根系免受土壤病原体侵害的潜在影响。在秘鲁的温室条件下同时进行了两项试验。第一项试验着重评估AMF接种的生物肥料效应，而第二项试验则检测对根结线虫 的生物保护效应。总体而言，结果表明，对 幼苗接种AMF能积极改善其生长发育，特别是生物量、株高和叶片养分含量。当幼苗接触 时，接种AMF的植株的生长也明显高于未接种AMF的植株。AMF的存在显著抑制了线虫繁殖，尤其是 ，特别是在接触线虫之前接种时。双重AMF接种不一定能促进作物生长，但显著提高了叶片中的磷和钾含量。这些发现为开发基于AMF的产品作为农业投入物提供了有力依据，以促进养分利用和吸收，并保护作物免受病虫害侵害，特别是那些本地适应本地作物和种植条件的产品。
