Microbiological Parameters

Plants interact with beneficial microbes living in their rhizosphere, promoting their growth and development. In arid ecosystems, specific plant-associated microbes grant plants access to nutrients that would otherwise be inaccessible. Arbuscular mycorrhizal fungi (AMF) are probably one of the better known belowground functional networks with plants. AMF plays a crucial role in plant performance and consequently in ecosystem functioning. AMF activities also determine the bio-availability of nutrients and therefore soil fertility. The main objective of the present study was to evaluate the plant-AMF interactions on soil functions under arid ecosystem in Tunisia. AMF colonization was evaluated by visual observation of AMF in fine roots of Astragalus corrugatus and Lotus creticus on Bou-Hedma National Park in Tunisia. Mycorrhizal colonization varied between plants, and the spore number was significantly different across rhizosphere soils. Statistical analysis showed a clearly positive correlation between the number of spores and plant-mycorrhizal intensity. For microbiological proprieties, our results showed that mycorrhizal plants improved significantly the different microbiological parameters. The results of the present study specified the association plant-AMF and highlight AMF importance as a tailored mechanism of plant adaptation to arid ecosystems.

Agricultural practices are known to affect the diversity and efficiency of arbuscular mycorrhizal fungi (AMF) in improving overall plant performance. In the present study we aimed to compare the abundance, richness, and diversity of AMF communities under organic farming of a desert ecosystem in the Arabian Peninsula with those of an adjacent conventional farming system and native vegetation. In total, 12 sites, including six plant species, were sampled from both farming systems and the native site. Spore morphotyping revealed 24 AMF species, with 21 species in the organic farming system, compared to 14 species in the conventional site and none from rhizosphere soil of a native plant (Tetraena qatarensis). The AMF spore abundance, species richness, and Shannon–Weaver diversity index were high under organic farming. In both systems, the AMF community composition and abundance associated with different crops followed similar trends, with pomegranates having the highest values followed by limes, grapes, mangoes, and lemons. Our results show that organic farming in such a desert ecosystem promotes AMF diversity. These data imply that AMF might play an important role in the sustainable production of food in resource-limited desert habitats.

Arbuscular mycorrhizal fungi (AMF) are naturally scattered and symbiotic with various tree species, AMF is able to improve plant adaptation to extreme soil conditions. About thirty-seven years Unilak, has been built in Riau Province, precisely in Rumbai Pekanbaru City. How is the existence of FMA on the developed campus land? Is the focus of this paper. Soil sampling for AMF observation refers to the modified ICRAF method. The extraction of AMF spores followed the pour and wet filter method followed by centrifugation techniques. Based on the morphological characteristics of the extracted AMF spores, it was identified to the genus level. The research series showed that the presence of AMF on the Unilak campus area contained 13 types of spores from the genus Acaulospora, Gigaspora, Glomus and Sclerocystis.
