Abstract

Tomato (Solanum lycopersicum L.) cultivation is economically important but often relies on excessive chemical inputs that degrade soil health. Agroecological practices, such as intercropping and arbuscular mycorrhizal fungi (AMF), provide sustainable alternatives. However, AMF effectiveness depends on strain–host compatibility and inoculum origin. To address this, a greenhouse experiment arranged in a randomized complete block design (RCBD) evaluated the interactive effects of three companion systems; TT (tomato/tomato), TG (tomato/garlic, Allium sativum L.), and TF (tomato/faba bean, Vicia faba L.) and four AMF inoculants; native Moroccan consortium (Native AMF, Rhizophagus irregularis, Claroideoglomus etunicatum and Funneliformis mosseae), a commercial strain (Gi, Glomus iranicum), a collection strain (Ri, Rhizophagus irregularis) and a non-inoculated (Control), on tomato growth and soil microbial activities. Root colonization increased by +40.10% under Native AMF–TF compared to Native AMF–TT. This stimulated soil enzymatic activity and nutrient availability, notably increasing P₂O₅ (+74.04%) under Native AMF–TF compared to Control–TT. Consequently, these improvements enhanced leaf chlorophyll (+41.35%) and fruit set (+199.48%) under Native AMF–TF, while Native AMF–TG maximized stem diameter (+41.10%) compared to Control–TT. These results support the combination of native AMF and intercropping as a sustainable strategy for horticultural tomato production and soil health.

摩洛哥本地AMF菌株和间作对农业生态系统中土壤酶活性、菌根定植和番茄生产力的协同效应

番茄（Solanum lycopersicum L.）种植在经济上很重要，但往往依赖于过度的化学物质投入，从而降低土壤健康。农业生态实践，如间作和丛枝菌根真菌（AMF），提供了可持续的替代方案。然而，AMF的有效性取决于菌株与宿主的相容性和接种源。为了解决这一问题，采用随机完全区设计（RCBD）安排温室试验，评估了三个伴生系统的相互作用效应；TT（番茄/番茄）、TG（番茄/大蒜，Allium sativum L.）、TF（番茄/蚕豆，Vicia faba L.）和4种AMF接种剂；摩洛哥本地联合菌群（原生AMF，不规则根噬菌，烟状芽孢杆菌和mosefuneliformis），商业菌株（Gi, Glomus iranicum），收集菌株（Ri，不规则根噬菌）和非接种菌株（对照）对番茄生长和土壤微生物活性的影响。与原生AMF-TT相比，原生AMF-TF处理的根定植量增加了40.10%。这刺激了土壤酶活性和养分有效性，与Control-TT相比，在Native AMF-TF下显着增加了P₂O₅（+74.04%）。结果表明，与对照相比，AMF-TF处理能显著提高叶片叶绿素（+41.35%）和坐果数（+199.48%），而AMF-TG处理能显著提高茎粗（+41.10%）。这些结果支持本地AMF与间作相结合作为园艺番茄生产和土壤健康的可持续战略。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
