Resumen o descripción

Arbuscular mycorrhizal fungi (AMF) promotes plant growth on most cases through the transport of nutrients from the soil to the roots. In recent decades, they have also been used as biological control agents against various plant pathogens and the results show decreased incidence and / or severity of the disease due to the mycorrhizal symbiosis. Therefore, the aim of this study was to evaluate the effect of mycorrhizal plants Agave cupreata in bioprotection against Fusarium oxysporum. A. cupreata plants seven month old, mycorrhizal and non-mycorrhizal under greenhouse conditions were used to evaluate the effect of bioprotection against F. oxysporum. The severity of the disease (SE) based on the observed damage in the leaves (chlorosis and wilting) of plants A. cupreata was evaluated by an ordinal scale, at 20 and 90 days after inoculation of the plant pathogen. The results showed colonization of fungi (AMF) in agave plants, regarding bioprotection, plants of A. cupreata presented initial wilt symptoms and severity of disease averaged 1.3 to 1.82 (first yellow leaf low, plant damage between 8-21%) with no significant differences (Kruskal-Wallis, p≤0.05) between plants with and without AMF at 90 d after inoculation with F. oxysporum strain FPC. This result was probably due to the physiology of the plant, so more time action pathosystem (mycorrhized agave-F. oxysporum) is required to assess the bioprotection of AMF against F. oxysporum.
