Bioprospection: in vitro antimicrobial potential of the leaf extract of mycorrhizal guava infected by Meloidogyne enterolobii on Klebsiella pneumoniae.

Guava (Psidium guajava L.), is adapted to tropical and subtropical climates, and, in addition to its nutritional value, has great medicinal potential. One of the medicinal effects is antibacterial, and this can be identified from the phytochemicals present in its various parts, especially the leaf, which contains flavonoids, phenols, and tannins, as well as phytocomposites with antibacterial action.

Application of Arbuscular Mycorrhizal Fungi during the Acclimatization of to Induce Tolerance to .

An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite . The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (, , , and a non-inoculated control) in the presence or absence of with five replicates. The following characteristics were evaluated after 270 days of mycorrhization and 170 days of inoculation: height, number of leaves and tillers, fresh mass of aerial and subterranean parts, dry mass of aerial parts, foliar area, nutritional content, mycorrhizal colonization, AMF sporulation, and the number of galls, egg masses, and eggs.
