“…In comparison, spores' number/ 100 g of soil was of 697 spores/100 g soil recorded in site 1 of the second station greater than that of site 2 in the order of 169 spores/100 g soil with a dominance of the genus Dentiscutata nigra (32.13%) and Acaulospora denticulata (14.77%) (Figure 7). These two species were more prevalent than Glomus etunicatum (16.26%), Acaulospora gedanensis (10.52%) or Glomus macrocarpum and much more represented in the AMF community structure in southern area (Sellal et al, 2017). Regarding our findings about the number of spores extracted from the soil of argan trees, they seem to be lower than those cited by El Maati et al Moreover, it is known that the same fungus can colonise many plant species.…”

“…At the same time, our assessment of the species' richness revealed some differences amongst the studied sites and stations. This variation has also marked the investigated sites of southern Morocco (Sellal et al, 2017;2021). A similar trend was observed for the number of spores in a 100 g soil; thereby, the highest spore density (585 spores/100 g soil) was related to site 4 of the first station followed by 518 spores/100 g soil, 204 spores/100 g soil, 201 spores/100 g soil, 154 spores/100 g soil, 101 spores/100 g soil, and 78 spores/100 g soil, detected respectively in sites 2, 5,7, 1,6 and 3.…”

“…According to the classification of Oehl and Sieverding (2011), these AMF belonged to 7 genera Claroideoglomus, Funneliformis, Glomus, Rhizophagus, Pacispora, Acaulospora, Dentiscutataand five 9 families: Glomeraceae (7 species), Acaulosporaceae (10 species), Pacisporaceae (2 species), Claroideoglomeraceae (2 species), Gigasporaceae (1 species). Interestingly, based on the results related to AMF community composition of argan forests in the south's areas (Sellal et al, 2017) share a number of species to that highlighted here viz, Claroideoglomus etunicatum, Endogone versiformis, Glomus macrocarpum, Acaulospora denticulata, Acaulospora rehmii, Glomus aureum, Entrophospora infrequens, Dentiscutata nigra, Acaulospora sp1, Rhizophagus intraradices, Funneliformis mosseae, Glomus sp.…”

The argan tree, an endemic species in Morocco, has been exhaustively studied in its southwestern range but neglected in its northeastern territory. Thus, the present study sets as objectives the identification of arbuscular mycorrhizal fungi and the evaluation of the argan tree’s roots’ mycorrhization level in two stations: one in the region of Béni Snassène (Berkane): Jebel Takermine with 7 prospected sites and the other at Jebel Aklim Alkabir with 2 sites. At the first station (Jebel Takermine), the mycorrhizal frequency of Argania spinosa roots varied between 64% and 100% with the root mycorrhizal intensity in the range of 30.77% and 66%. The arbuscular contents are higher at sites 2 (50.46%), 4 (50.33%), 7 (39.44%) and 1 (30.5%) against 18% and 20% at sites 6, 5 and 3. Argan trees from Jbel Aklim Alkbir, exhibited a high mycorrhization frequency and intensity ranging from 88% to 100% and between 39.4% and 73.4% respectively. Regarding arbuscular and vesicular rates, the highest values were associated to the roots of site 1 with 59.3% and 29.4% respectively compared to the lowest rates of 20% and 14% in those of site 2. Spore densities in the rhizosphere of the studied argan trees in the two stations were in the range of 78 and 697 spores/100 g of soil. The identification of isolated mycorrhizal spores revealed the presence of 28 species encompassing 7 genera: Acaulospora, Dentiscutata Claroideoglomus, Funneliformis, Glomus, Rhizophagus, Pacispora, and 5 Families: Glomeraceae (7 species), Acaulosporaceae (10 species), Pacisporaceae (2 species), Claroideoglomeraceae (2 species), Gigasporaceae (1 species).

“…increased young olive plant growth and nutrient uptake in three olive genotypes. Furthermore, a mycorrhizal consortium of Glomus, Acaulospora, Gigaspora, Entrophospora, and Scutellospora species, increased the Na, Ca, and P concentrations in nutrient contents of 'Haouzia' olive cultivars under sandy loam soil conditions [32] and it was responsible for young olive plant-growth enhancement [12,32,33].…”

The olive tree (Olea europaea L.) is an emblematic, long-living fruit tree species of profound economic and environmental importance. This study is a literature review of articles published during the last 10 years about the role of beneficial microbes [Arbuscular Mycorrhizal Fungi (AMF), Plant Growth Promoting Rhizobacteria (PGPR), Plant Growth Promoting Fungi (PGPF), and Endophytes] on olive tree plant growth and productivity, pathogen control, and alleviation from abiotic stress. The majority of the studies examined the AMF effect using mostly Rhizophagus irregularis and Glomus mosseae species. These AMF species stimulate the root growth improving the resistance of olive plants to environmental and transplantation stresses. Among the PGPR, the nitrogen-fixing bacteria Azospirillum sp. and potassium- and phosphorous-solubilizing Bacillus sp. species were studied extensively. These PGPR species were combined with proper cultural practices and improved considerably olive plant’s growth. The endophytic bacterial species Pseudomonas fluorescens and Bacillus sp., as well as the fungal species Trichoderma sp. were identified as the most effective biocontrol agents against olive tree diseases (e.g., Verticillium wilt, root rot, and anthracnose).

“…All of these types of plants are hosts of AMF. Several other studies related to the application of AMF in the manufacture of cuttings have been carried out on bougainvillea [15], olive [16], and andalas plant species which are endemic to West Sumatra [17]. The results of pre-study observations showed that in the rhizosphere of L. garciae, which grows naturally in the Green Open Space of the Faculty of Forestry Universitas Tanjungpura, an indigenous AMF population was found.…”

Litsea garciae Vidal. (engkala, kalangkala) is a fruit-producing plant useful as a potential medicinal plant and food. The availability of seedlings is a must if their potential is to be developed. The study aimed to evaluate the formation and growth of roots and shoots of L. garciae shoot cuttings in response to growth regulators and arbuscular mycorrhizal fungi (AMF) inoculation. The study used a factorial experiment with a completely randomized design. The treatments tested were growth regulators (without and with rootone-F) and AMF inoculation (without and with AMF). The shoot cuttings were planted in a mixture of cocopeat and husk charcoal (2:1 v/v) and placed in a propagation box in a screen house for 12 weeks. The live percentage, the percentage of callus cuttings, the percentage of rooted cuttings, and the percentage of cuttings sprouting all shoot cuttings planted reached 100%. The interaction between rootone-F and AMF had no significant effect on initiating root and shoot growth. However, cuttings treated without or with rootone-F showed a positive response to AMF inoculation, particularly in primary root formation and secondary root count. The secondary roots’ length and wet and dry weights of the cuttings with rootone-F were significantly lower than those without rootone-F.
