The objective of this research was to evaluate the bioprotective effect of two arbuscular mycorrhizal fungi, Rhizoglomus dunense and Paraglomus laccatum, on the damage caused by Meloidogyne incognita in coffee seedlings of the Caturra variety. A completely randomized design (CRD) with factorial arrangement was used to evaluate plant vegetative growth and the bioprotective effect of AMF. Rhizoglomus dunense colonized up to 85% of the coffee root system; this species also significantly increased the vegetative development of the plants and influenced the increase in nutritional concentration (318.3 mg/kg nitrogen, 7.9 mg/kg phosphorus and 231.0 mg/kg potassium), presenting a biofertilizing effect. When evaluating the bioprotective effect, Rhizoglomus dunense reduced the degree of severity of Meloidogyne incognita in coffee roots, reducing the degree of severity from 4.4 to 2.6. Similarly, this mycorrhiza had a positive effect of bioprotection of coffee roots against Meloidogyne incognita, reducing the population of nematodes in the roots, decreasing from 193 to 71 nematodes/100 g soil. In the evaluations of enzymatic and non-enzymatic antioxidant activity in coffee seedlings of the caturra variety infested with Meloidogyne incognita, a reduction in the concentration of reduced glutathione was observed in coffee plants inoculated only with Rhizoglomus dunense (2522.34 mol/g to 1957.97 mol/g); for the evaluation of B-glucanase activity, the highest reaction value was obtained in the treatment inoculated with Rhizoglomus dunense and Meloidogyne incognita (95.26 mol/g). In conclusion, Rhizoglomus dunense showed bioprotective potential, reducing the damage caused by Meloidogyne incognita on coffee seedlings.
