“…Variations in the number of AMF spores were also observed in studies with agricultural soils of the caatinga under the influence of factors such as: plant species, seasonality (dry/rainy period), and type of management (conventional or conservationist) (LIMA et al, 2007;SANTOS et al, 2013;SOUSA et al, 2014;CARDOZO JUNIOR et al, 2018). The production of spores can be stimulated by stress situations, such as water deficit, temperature increase, soil disturbance, end of the growth cycle of annual plants or the productive cycle of perennial plants, and the high concentration of chemical substances, such as fertilizers, biocides, and plant metabolism regulators (SMITH & READ, 2008;BRUNDRETT & TEDERSOO, 2018;SALOMON et al, 2022).…”

Arbuscular mycorrhizal fungi (AMF) increase the absorption surface of roots, providing greater absorption of water and nutrients from the soil by plants. Thus, it is important to know how arbuscular mycorrhizae are affected by factors such as phenology, management and varieties in mango (Mangifera indica) orchards in the irrigated semi-arid region. With this objective, soil and root samples were collected during the vegetative, flowering and fruiting stages, and in the water stress period before flowering, always on the same trees. The study was carried out in mango orchards of the Keitt and Palmer varieties, in agricultural farms located in Juazeiro - BA and Petrolina - PE, both under conventional management (with fertilizers and paclobutazol). The soil was used to quantify the number of AMF spores and phosphorus content. Mycorrhizal colonization in roots was evaluated in qualitative terms (presence of hyphae, vesicles and arbuscles) and quantitative terms (% of colonization). Total mycorrhizal colonization was high, with averages above 65%, and higher values in the fruiting period. Colonization by vesicles and arbuscles was on average above 45% and 17%, respectively, with higher means also during fruiting. The number of AMF spores in the soil averaged over 130 spores in 50 g of soil, with higher values in the period of water stress. The phosphorus content in the soil did not influence mycorrhizal colonization and the number of spores in the soil. The association of AMF with mango trees was generally affected by management and phenology, regardless of the cultivated varieties.
