An experiment was carried out to assess the benefits of native arbuscular mycorrhizal fungi (AMF) for banana plants cv. ‘Nendran’. The AMF species applied wereFunneliformis mosseaeandGlomus microcarpum, which were identified in a previous survey as the most common root associates ofMusaspp. in traditional monoculture banana fields. Spores of both the AMF species isolated from the natural banana fields were mono-cultured and used in the experiment, individually and in combination, at two inoculum spore levels (2500 or 5000 spores). We evaluated the root colonising potential of AMFs and their effects on plant height, chlorophyll content and leaf N, P and K concentrations at regular intervals up to 90 days after inoculation. All the inoculated plants showed more than 80% root colonisation. Increase in chlorophyll content in the leaves was found significant in all treatments, with the exception of the combination of 5000 spores ofF. mosseae and5000 spores ofG. microcarpumeach. Increases in leaf N, P and K were found in all the inoculated plants as compared to control (sterile soil without any AMF). While a significant reduction in soil available nitrogen and soil pH was observed in all treatments with inoculation, the soil available phosphorus and soil total organic carbon were increased by inoculation. Overall data revealed positive effects of AMF species in banana, especially during its early growth. As AMF species were isolated from fields differing in relation to banana variety and soil type and have positive effects in banana nutrition, an integrated soil fertility management using AMF appears promising.

原生丛枝菌根真菌分离物（Funneliformis mosseae 和 Glomus microcarpum）可改善香蕉植物的株高和营养状况

进行了一项实验以评估天然丛枝菌根真菌 (AMF) 对香蕉植物 cv 的益处。'南德兰'。应用的 AMF 种类是苔藓漏斗鱼和小果球囊，在之前的调查中被确定为最常见的根关联穆萨spp. 在传统的单一栽培香蕉田。从天然香蕉田中分离出的两种 AMF 物种的孢子被单培养，并在实验中以两种接种孢子水平（2500 或 5000 个孢子）单独和组合使用。我们在接种后 90 天内定期评估 AMF 的根系定殖潜力及其对植物高度、叶绿素含量和叶片 N、P 和 K 浓度的影响。所有接种的植物都表现出超过 80% 的根系定殖。除 5000 个F. mosseae 和5000个孢子G. microcarpum每个。与对照（没有任何 AMF 的无菌土壤）相比，在所有接种的植物中发现叶片 N、P 和 K 的增加。虽然在所有接种处理中都观察到土壤有效氮和土壤 pH 值显着降低，但土壤有效磷和土壤总有机碳通过接种增加。总体数据揭示了 AMF 物种对香蕉的积极影响，尤其是在其早期生长期间。由于 AMF 物种是从与香蕉品种和土壤类型相关的不同田地中分离出来的，并且对香蕉营养有积极影响，因此使用 AMF 进行综合土壤肥力管理似乎很有希望。
